Description

  The present invention relates to an X-ray apparatus including an X-ray tube that irradiates X-rays and an X-ray detector that detects irradiated X-rays, a control device and a control method for controlling the X-ray device, and a control program.

  Taking an example of imaging as an inspection in an X-ray apparatus will be described. In an X-ray imaging apparatus having an X-ray tube, a plurality of X-ray detectors, and a console for controlling the X-ray detector, when performing imaging based on imaging order information, Therefore, it is necessary to select and specify the X-ray detector used at the time of imaging. As the imaging order information, for example, the size of the subject, the size of the region of interest to be imaged, the region of the region of interest (imaging region), the method of imaging the imaging region from which direction (for example, the front of the chest or the side of the chest), X-ray detector sensitivity.

  Regarding the designation of the X-ray detector, there is a method (the former method) of explicitly selecting from among the X-ray detectors that can be used by the operator before imaging, or the radiographing order information and the X-ray detector specific A method of specifying an X-ray detector to be used based on a detector ID associated with information (hereinafter referred to as “detector ID”) in advance and associated with imaging order information selected by the console at the time of imaging (the latter) Method).

  In the case of the latter method, for example, a large X-ray detector is associated with an imaging order related to a normal imaging region such as the chest or abdomen, and a small X-ray detector is associated with an imaging order for limbs or children. Thus, it is possible to perform imaging using an X-ray detector having an optimal size corresponding to the imaging region without requiring an operation of manually switching the X-ray detector used before imaging. In recent years, a digital X-ray detector capable of communicating with a console is used as the X-ray detector, and a flat panel X-ray detector (FPD: Flat Panel Detector) is used as the digital X-ray detector. It is done.

  In addition to the former and the latter methods, a flat panel X-ray detector (hereinafter referred to as “FPD”) is attached to a bucky device installed on each stand or table in imaging using a standing imaging stand or a standing imaging table. There is also a method in which the Bucky device detects a detector ID of the FPD and automatically designates it as an X-ray detector that uses the FPD (for example, see Patent Document 1). ).

  In addition, in an X-ray imaging apparatus capable of wireless communication (wireless communication is possible), a corresponding X-ray detector is selected from a plurality of X-ray detectors based on imaging order information (such as spatial resolution and the size of a region of interest). The use is disclosed (for example, see Patent Document 2). In particular, paragraph number “0016” of Patent Document 2: Japanese Patent Application Laid-Open No. 2002-191586 discloses that a thin X-ray detector is separately arranged for photographing the extremities and the like.

JP 2012-105895 A JP 2002-191586 A

However, the conventional example having such a configuration has the following problems.
That is, for example, when the imaging order information and the detector ID are associated in advance as in JP-A-2012-105895, it is assumed that the associated detector ID is used on the X-ray imaging apparatus. Associated X-ray detectors.

  On the other hand, X-ray detectors typified by FPD and the like are portable, and those capable of wireless communication such as Japanese Patent Application Laid-Open No. 2002-191586 have become common, and one X-ray detector is available. It has become possible to use a detector shared by a plurality of X-ray imaging apparatuses. When the above usage is performed, one X-ray detector cannot be used simultaneously by a plurality of X-ray imaging apparatuses, and can only be used by one X-ray imaging apparatus. Therefore, the X-ray detector cannot be used from an X-ray imaging apparatus other than the X-ray imaging apparatus using the X-ray detector. Therefore, in the X-ray imaging apparatus using the X-ray detector as described above, usable X-ray detectors may differ depending on the situation.

  Thus, when an X-ray detector is shared by a plurality of X-ray imaging apparatuses, the associated X-ray detector is used by another X-ray imaging apparatus and used by the associated X-ray imaging apparatus. There may be situations where it is not possible. In such a situation, it is not always possible to use at the timing of actual shooting.

  Further, in the case of an imaging method that does not use a bucky device (imaging by a general imaging technique), and in the case of imaging in an imaging device that does not have a bucky device such as a roundabout device, the X-rays stored in the above-described bucky device The detector cannot be selected automatically. In addition, if the X-ray detector having the largest size among the available X-ray detectors is always automatically selected, the range of the X-ray detector necessary for imaging (the region of the imaging region) Range). However, although X-ray detectors are becoming lighter due to technological advances, there are many X-ray detectors that weigh about several kilograms, and it is as much as possible when small technicians and female engineers take pictures. There is also a need to use a small X-ray detector.

  The present invention has been made in view of such circumstances, and can be used when there is a possibility that the usable X-ray detector may change dynamically at the timing of performing the inspection. An object of the present invention is to provide an X-ray apparatus capable of automatically selecting an X-ray detector suitable for the purpose from among the detectors, a control device and a control method for controlling the X-ray apparatus, and a control program.

In order to achieve such an object, the present invention has the following configuration.
That is, the X-ray apparatus according to the present invention is an X-ray apparatus including an X-ray tube for irradiating X-rays and an X-ray detector for detecting the irradiated X-rays, and usable X-ray detection. X-ray detector detection means for detecting a detector and X-ray detector selection means for selecting an X-ray detector to be selected based on examination order information, and detected by the X-ray detector detection means The X-ray detector selected by the X-ray detector selection means is selected from the X-ray detectors.

  [Operation / Effect] According to the X-ray apparatus of the present invention, the X-ray detector detection means for detecting usable X-ray detectors and the X-ray detector to be selected based on the inspection order information are provided. X-ray detector selection means for selecting. Then, among the X-ray detectors detected by the X-ray detector detection means, an X-ray detector is selected by the X-ray detector selection means based on the examination order information. As described above, since the corresponding X-ray detector is selected based on the inspection order information among the usable X-ray detectors, the usable X-ray detector can be dynamically changed at the timing of performing the inspection. If there is a possibility, an X-ray detector suitable for the purpose (in the inspection order) can be automatically selected from the available X-ray detectors. As a result, the burden on the operator during the inspection operation can be reduced.

  In the X-ray apparatus according to the above-described invention, an example of the inspection order information is an X-ray detector size necessary for inspection (hereinafter also referred to as “recommended detector size”), and the X-ray detector selecting means An X-ray detector is selected based on the X-ray detector size (recommended detector size). When an X-ray detector having the same size that matches the X-ray detector size (recommended detector size) can be used, the X-ray detector having the same size can be selected. In particular, as described later, when there is one X-ray detector of the same size among the usable detectors, the corresponding X-ray detector is selected.

  Further, when there is one usable X-ray detector, the X-ray detector is selected as follows. That is, in the X-ray apparatus according to the above-described invention, when the X-ray detector selected by the X-ray detector selection means among the X-ray detectors detected by the X-ray detector detection means is one X-ray detector of the same size Includes first X-ray detector selection means for selecting the corresponding X-ray detector.

  In addition, when there are a plurality of X-ray detectors of the same size, the operator manually sets the priority order for using the X-ray detector and automatically sets the X-ray detector according to the priority order. You may make it choose. That is, in the X-ray apparatus according to the above-described invention, the priority setting means for setting the priority order for using the X-ray detector and the X-ray detector is selected according to the priority order set by the priority setting means. Second X-ray detector selection means. In this case, it is useful when there are a plurality of X-ray detectors of the same size among the X-ray detectors detected by the X-ray detector detection means, and the second X-ray detector selection means is divided into a plurality of The X-ray detector having the highest priority set by the priority setting means is selected from the corresponding X-ray detectors. For example, when setting the priority order based on the sensitivity of the X-ray detector, the X-ray detector having the highest sensitivity is set to the highest priority order, and the X-ray detector is set to a lower order as the sensitivity becomes lower. Set. As a result, an X-ray detector with high sensitivity can be preferentially used from among usable X-ray detectors, and the higher the sensitivity, the lower the X-ray irradiation dose, and the subject (patient ) Leads to a reduction in exposure.

  When there are a plurality of X-ray detectors having the same size, the X-ray detector having the highest priority is selected from the plurality of X-ray detectors having the same size as described above. When setting the priority order based on the sensitivity of the X-ray detector, “available X-ray detector” → “X-ray detector size (recommended detector size)” → “X-ray detector The X-ray detector is selected in the order of “sensitivity” → “priority”.

  When an example of the inspection order information is an X-ray detector size (recommended detector size) necessary for the inspection, a third X-ray detector selection unit that performs the following selection is provided. That is, when an X-ray detector having the same size as the X-ray detector size (recommended detector size) can be used, the third X-ray detector selecting means selects the X-ray detector having the same size. . On the other hand, an X-ray detector of the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector larger than the X-ray detector size (recommended detector size) is used. If possible, the third X-ray detector selecting means selects the smallest X-ray detector from the corresponding large X-ray detectors. An X-ray detector of the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector larger than the X-ray detector size (recommended detector size) can be used. In some cases, as described in the section “Problems to be solved by the invention”, if an X-ray detector having a size larger than the X-ray detector size (recommended detector size) is selected, The range of the X-ray detector necessary for the inspection (including the imaging) (the range of the region of the inspection site) can be covered. On the other hand, considering the need to use as small an X-ray detector as possible, the smallest X-ray detector is selected from the corresponding large X-ray detectors to meet the above needs. However, it is possible to cover the range of the X-ray detector necessary for the inspection (the region of the region to be inspected).

  Furthermore, an X-ray detector of the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector larger than the X-ray detector size (recommended detector size) can be used. If the X-ray detector having a size smaller than the X-ray detector size (recommended detector size) is usable, the third X-ray detector selecting means detects the X-ray of the corresponding small size. The X-ray detector of the largest size is selected from the instruments. As a result, an X-ray detector having the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector having a size larger than the X-ray detector size (recommended detector size) can be obtained. Even if it is not usable, the X-ray detector having the largest size among the corresponding X-ray detectors (smaller than the X-ray detector size) is selected as the X-ray detector size ( It can be used as an X-ray detector having a size as close as possible to the recommended detector size).

  In addition, although the example performed based on the sensitivity of the X-ray detector when the operator manually sets the priority order has been described, the X-ray detector is automatically selected based on the sensitivity of the X-ray detector. You may do it. That is, the inspection order information is the sensitivity of the X-ray detector in addition to the X-ray detector size (recommended detector size) described above, and is the X-ray detector detected by the X-ray detector detection means. The X-ray detector selection means selects an X-ray detector based on the X-ray detector size (recommended detector size), and selects an X-ray detector based on the usable X-ray detector. The X-ray detector having the highest sensitivity is selected. When an X-ray detector is automatically selected based on the sensitivity of the X-ray detector, “available X-ray detector” → “X-ray detector size (recommended detector size)” → “X-ray detector” The X-ray detector is automatically selected in the order of “sensitivity of detector” → “X-ray detector having the highest sensitivity”. As a result, the X-ray detector having the highest usable sensitivity among the X-ray detectors selected based on the X-ray detector size (recommended detector size) can be used. Can reduce the exposure dose of the subject (patient).

  Even when an X-ray detector is automatically selected based on the sensitivity of the X-ray detector, if there is only one X-ray detector having the highest usable sensitivity, the corresponding X-ray detector is used. First X-ray detector selection means for selecting.

  Even when an X-ray detector is automatically selected based on the sensitivity of the X-ray detector, when there are a plurality of usable X-ray detectors, the priority order of using the X-ray detector is set. The operator may manually set the X-ray detector according to the priority order. That is, similarly, priority order setting means for setting the priority order for using the X-ray detector, and second X-ray detector selection for selecting the X-ray detector according to the priority order set by the priority order setting means. Means. In this case, it is useful when there are a plurality of X-ray detectors with the highest sensitivity that can be used, and the second X-ray detector selection means is a priority setting means among the plurality of X-ray detectors. The X-ray detector with the highest priority set in is selected.

  Even when the X-ray detector is automatically selected based on the sensitivity of the X-ray detector, the third X-ray detector selection means for performing the selection as described above is provided. That is, when an X-ray detector having the same size as the X-ray detector size (recommended detector size) can be used, the third X-ray detector selecting means selects the X-ray detector having the same size. . On the other hand, an X-ray detector of the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector larger than the X-ray detector size (recommended detector size) is used. If possible, the third X-ray detector selecting means selects the smallest X-ray detector from the corresponding large X-ray detectors. Further, the X-ray having the highest sensitivity among the corresponding X-ray detectors based on the usable X-ray detector among the X-ray detectors of the smallest size selected by the third X-ray detector selection means. Select a detector. By selecting the smallest X-ray detector from the corresponding large-sized X-ray detectors, the X-ray detector required for the inspection can be met while meeting the need to use the smallest X-ray detector as much as possible. The range (the range of the region to be examined) can be covered. Furthermore, by selecting the X-ray detector with the highest sensitivity from among the X-ray detectors of the same size corresponding to a plurality, use the X-ray detector with the highest sensitivity that can be used while meeting the above needs. The higher the sensitivity, the smaller the X-ray irradiation dose, and the lower the exposure of the subject (patient).

  Even when the X-ray detector is automatically selected based on the sensitivity of the X-ray detector, the third X-ray detector selection means performs the selection as described above. That is, an X-ray detector having the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector larger than the X-ray detector size (recommended detector size) can be used. If the X-ray detector having a size smaller than the X-ray detector size (recommended detector size) is usable, the third X-ray detector selecting means detects the X-ray of the corresponding small size. The X-ray detector of the largest size is selected from the instruments. Then, based on the usable X-ray detector among the largest X-ray detectors selected by the third X-ray detector selection means, the X-ray having the highest sensitivity among the corresponding X-ray detectors. Select a detector. As a result, an X-ray detector having the same size as the X-ray detector size (recommended detector size) cannot be used, and an X-ray detector having a size larger than the X-ray detector size (recommended detector size) can be obtained. Even if it is not usable, the X-ray detector having the largest size among the corresponding X-ray detectors (smaller than the X-ray detector size) is selected as the X-ray detector size ( It can be used as an X-ray detector having a size as close as possible to the recommended detector size). Furthermore, an X-ray detector having the highest usable sensitivity can be used, and the higher the sensitivity, the lower the X-ray irradiation dose, leading to a reduction in the exposure of the subject (patient).

  In the X-ray apparatus according to these inventions, selection / selection is preferentially performed as described below rather than selection by the above-described X-ray detector selection means or selection of an X-ray detector based on an available X-ray detector. You may do it.

  For example, the X-ray detector is provided with first change setting means for changing and setting the X-ray detector that was in an unusable state to be usable, and the X-ray detection changed and set to be usable by the first change setting means. Select the vessel with the highest priority. For example, when an X-ray detector is shared by a plurality of X-ray devices, the X-ray detector cannot be used in the other X-ray device by using the X-ray detector in one X-ray device. . When it is desired to use the X-ray detector in the other X-ray apparatus, the X-ray detector is given the highest priority in the other X-ray apparatus by changing the setting to the usable state by the first change setting means. Make a selection.

  On the contrary, the X-ray detector selected as the usable X-ray detector is provided with a second change setting means for changing the X-ray detector to an unusable state, and is changed to an unusable state by the second change setting means. When set, the X-ray detector selection unit again selects the usable X-ray detectors detected by the X-ray detector detection unit, and the X-ray detector is selected again.

  Further, for example, one X-ray detector among usable X-ray detectors is selected with the highest priority. For example, if an inspection order that has already been inspected is subjected to a copying operation or an order duplication operation, and a new inspection order is added, the X-ray detector used immediately before re-imaging is performed. If the X-ray detector that is the target of the added inspection order is usable, the X-ray detector may be used by selecting the X-ray detector with the highest priority. .

  Further, the control device for controlling the X-ray apparatus according to these inventions includes an X-ray detector detecting means for detecting an available X-ray detector, and an X-ray detector to be selected based on the examination order information. Selecting an X-ray detector selected by the X-ray detector selecting means from among the X-ray detectors detected by the X-ray detector detecting means. It is a feature.

  Further, the present invention provides a control method for controlling an X-ray apparatus according to these inventions, an X-ray detector detecting step for detecting usable X-ray detectors, and an X-ray to be selected based on examination order information. Selecting an X-ray detector selected in the X-ray detector selection step from among the X-ray detectors detected in the X-ray detector detection step. It is characterized by.

  Also, a control program for causing a computer to execute a series of processes for controlling the X-ray apparatus according to these inventions, an X-ray detector detection process for detecting usable X-ray detectors, and inspection order information An X-ray detector selection process for selecting an X-ray detector to be selected based on the X-ray detector, and the X-ray detector selected among the X-ray detectors detected in the X-ray detector detection process. The selected X-ray detector is selected, and processing in these steps is executed by a computer.

  [Operation / Effect] According to the control device, the control method, and the control program according to the present invention, the usable X (detected by the X-ray detector detection means) can be used in the same manner as the X-ray device according to the above-described invention. Since the corresponding X-ray detector is selected based on the inspection order information among the line detectors, it can be used when there is a possibility that the X-ray detector that can be used changes dynamically at the timing of performing the inspection. X-ray detectors suitable for the purpose (in the inspection order) can be automatically selected from the various X-ray detectors.

  According to the X-ray apparatus, the control apparatus and control method for controlling the X-ray apparatus, and the control program according to the present invention, inspection order information among usable X-ray detectors (detected by the X-ray detector detection means) The appropriate X-ray detector is selected on the basis of the X-ray detector. Therefore, when there is a possibility that the usable X-ray detector may change dynamically at the timing of performing the inspection, the X-ray detector can be selected from among the usable X-ray detectors. An X-ray detector suitable for the purpose (in the inspection order) can be automatically selected.

It is a block diagram of a console concerning a modification. It is a block diagram of the console concerning the further modification.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram of an X-ray imaging apparatus according to the embodiment, and FIG. 2 is a block diagram of a console according to the embodiment. In the present embodiment, imaging will be described as an example of examination in the X-ray apparatus, and a round-trip X-ray imaging apparatus having a movable carriage will be described as an example of the X-ray apparatus.

  As shown in FIG. 1, the X-ray imaging apparatus according to this embodiment includes a mobile carriage 1, an X-ray tube 2 that irradiates X-rays toward a subject M as a patient, and irradiation from the X-ray tube 2. And a flat panel X-ray detector (FPD) 3 for detecting X-rays transmitted through the subject M. In FIG. 1, the movable carriage 1 includes a support column, an extendable arm, etc., one end of the extendable arm holds the X-ray tube 2, and the FPD 3 is held below the top plate on which the subject M is placed. The line tube 2 and the FPD 3 are provided so as to face each other. The movable carriage is not limited to the structure shown in FIG. 1 and includes a C-arm, one end of the C-arm holds an X-ray tube, and the other end of the C-arm holds an FPD. A structure in which the FPDs face each other may be used. In this embodiment, since the X-ray imaging apparatus is for round trips, the top plate on which the subject M is placed is installed independently of the X-ray imaging apparatus. The X-ray tube 2 corresponds to the X-ray tube in the present invention, and the flat panel X-ray detector (FPD) 3 corresponds to the X-ray detector in the present invention.

  In addition, the X-ray imaging apparatus includes an image processing unit 4 that performs image processing based on X-rays detected by the FPD 3, a controller 5 that performs overall control of each component, and an image processing unit 4 via the controller 5. Stores an X-ray image obtained by various image processing, a memory unit 6 for storing imaging order information, which will be described later, an input unit 7 for an operator such as an engineer to input data and commands (commands), The display unit 8 displays an X-ray image by the image processing unit 4 and explicitly displays an automatically selected FPD 3 to be described later. The controller 5 corresponds to the control device in the present invention, and the input unit 7 corresponds to the priority setting means in the present invention.

  The controller 5, the memory unit 6, the input unit 7 and the display unit 8 constitute a console 9. The image processing unit 4 may be included in the console 9. A specific configuration of the console 9 will be described later with reference to FIG.

  The FPD 3 has a detection surface in which a plurality of detection elements sensitive to X-rays are arranged in a two-dimensional matrix. The detection element detects the X-rays by converting the X-rays transmitted through the subject M into electrical signals, temporarily storing them, and reading the stored electrical signals. An electric signal detected by each detection element is converted into a pixel value corresponding to the electric signal, and an X-ray image is output by assigning the pixel value to each pixel corresponding to the position of the detection element. The output X-ray image is sent to the image processing unit 4 or the memory unit 6 via the controller 5. As described above, the FPD 3 includes a plurality of detection elements that detect X-rays arranged in a matrix (two-dimensional matrix), and is used in an X-ray imaging digital apparatus. The X-ray detector is not limited to the FPD, and may be an X-ray detector used in an X-ray imaging analog device such as an image intensifier (II).

  The FPD 3 may be a direct conversion type X-ray detector having a photoelectric conversion layer that converts X-rays directly into an electrical signal, or a scintillator that converts X-rays into light, and converted light. It may be an indirect conversion type X-ray detector that converts an X-ray into an electric signal indirectly by having a photoelectric conversion layer that converts the signal into an electric signal. Note that the output of an electrical signal with respect to the X-ray irradiation dose is proportional to the sensitivity of the FPD 3. Sensitivity changes according to the material which comprises the photoelectric converting layer and scintillator mentioned above. In this embodiment, the sensitivity of each FPD 3 is obtained before shooting, and is written and stored in the memory unit 6 as shooting order information.

  In the present embodiment, FPDs 3 having various sensitivities and FPDs 3 having various recommended detector sizes are prepared, and these FPDs 3 are shared by a plurality of X-ray imaging apparatuses.

  The image processing unit 4 and the controller 5 are configured by a central processing unit (CPU) and the like. The image processing unit 4 may be configured by a GPU (Graphics Processing Unit) or the like.

  The memory unit 6 is composed of a storage medium represented by ROM (Read-only Memory), RAM (Random-Access Memory), and the like. In the present embodiment, the X-ray image after the image processing by the image processing unit 4 obtained by the FPD 3 is written and stored, and the X-ray image is read out from the memory unit 6 as necessary, and the display unit 8 or printer ( (Not shown). Also, in this embodiment, imaging order information such as FPD size (recommended detector size) necessary for inspection and sensitivity of FPD 3 is written and stored, and by an FPD selection unit 52 (see FIG. 2) of the controller 5 described later. At the time of selection, the imaging order information is read from the memory unit 6 and sent to the FPD selection unit 52. Further, usable detector list information, which will be described later, is written and stored, and the detector list information is read out from the memory unit 6 at the time of detection (list-up) by the FPD detection unit 51 of the controller 5, which will be described later, to detect the FPD. Send to part 51.

  Here, in order to list (detect) usable FPDs 3, an operation for setting that the FPDs 3 are usable is performed in advance. A method for setting that the FPD 3 can be used is not particularly limited, but here, description will be given by taking authentication by communication means as an example. Specifically, in order to use the detector a that can be used in the device A in the device B, the communication between the device B and the detector a is performed using the communication means, and the detector a is connected to the device B. Authenticate and place detector a in a state belonging to device B.

  About the authentication by this communication means, it is preferable to authenticate using the communication means different from the communication means between a normal apparatus and a detector. For example, when communicating between devices and detectors using a wireless local area network (LAN), the devices and detectors are electrically connected using a wired cable, and the detectors are connected using a wired cable. Authentication is performed so as to belong to the specified device. On the other hand, when the device and the detector are normally communicated with each other by a wired cable, the device and the detector are authenticated by being communicated with each other by the infrared communication using the wireless LAN. I do. The authenticated detector is written and stored in the memory unit of the corresponding device as detector list information.

  Usually, multiple available detectors are authenticated. When authenticating a plurality of usable detectors, the same number of usable detectors as the communication means may be authenticated at the same time using a plurality of communication means (for example, wired cables), or each detector may be authenticated. You may authenticate sequentially.

  In addition, since it is considered that authentication operations are not performed frequently, when using multiple wired cables and simultaneously authenticating the same number of usable detectors as wired cables, communication between devices and detectors is usually performed. In addition, the cable for charging the detector may also be used as a cable for authentication.

  When authenticating sequentially to each detector, the detector / device to be authenticated is communicated to allow the device to authenticate the detector, and once authentication is completed, the next detector is authenticated. The communication processing between the already-detected detectors and devices is completed, and the operation for setting the next detector as a detector to be authenticated is sequentially performed on each detector. When the communication means is a wired cable, the detector is connected to the detector / device to be authenticated by electrically connecting the wired cable to the detector / device to be authenticated, and the detector is connected to the device. The communication process between the certified detector / device is completed by electrically disconnecting the wired cable from the certified detector / device, and the wired cable is electrically connected to the next detector / device. Thus, the operation of setting the next detector as a detector to be authenticated is sequentially performed on each detector.

  Here, when a plurality of devices share a detector, the detector is simultaneously authenticated to a plurality of devices in order to prevent the device from knowing which device the communication is with. Do not let it. For example, when the detector a is shared by the two devices A and B, when the detector a used in the device A is used in the device B, the detector from the detector list information is detected from the device A. a is deleted, and the apparatus B is made to authenticate the detector a. In this way, the two devices A and B are prevented from authenticating the detector a at the same time.

  Once the above-described authentication is performed, for example, the authentication may be performed for some reason such as causing another device to authenticate as described above, or deleting the detector information from the detector list information as described above. Unless it is canceled, there is no need to re-authenticate. Therefore, it is not necessary to authenticate again even if the apparatus is turned off or on.

  Moreover, you may perform registration operation regarding each detector before the authentication mentioned above. Here, the registration operation means an operation of writing and storing the information of the detector in the memory unit of the corresponding device. Only when the detector registered in the device is authenticated, the device can be used. Conversely, even if an authentication operation is performed on a detector that is not registered in the device, the detector that is not registered in the device cannot be used. In this way, only detectors that have performed both registration and authentication operations on the apparatus may be used. This registration operation can be performed in advance for all devices that may be used.

  In the above description, the authentication by the communication unit has been described as an example. However, in addition to the authentication by the communication unit, it may be set that a detector represented by the FPD 3 or the like can be used as described below. For example, if a wireless detector is moved out of the radio range, it is deleted from the usable detector list information even if it has been authenticated, and conversely, a wireless detector that was out of the radio range is moved out of the radio range. In this case, the detector may be automatically added to the usable detector list information. It can also be removed from the available detector list information by simply turning off the detector, and automatically turning on the detector based on the available detector list information by simply turning on the detector. May be set to be added automatically. That is, it is set so that the detector becomes unusable when communication with the apparatus becomes impossible and becomes usable when the detector becomes able to communicate with the apparatus.

  The input unit 7 includes a pointing device represented by a mouse, a keyboard, a joystick, a trackball, a touch panel, and the like. In the present embodiment, in order for the operator to manually set the priority order for using the FPD 3, the priority order is input based on the imaging order information such as the recommended detector size and the sensitivity of the FPD 3. As will be described later, in this embodiment, the recommended detector size and sensitivity are already used, such as selecting the FPD 3 based on the recommended detector size and selecting the FPD 3 having the highest sensitivity when considering the sensitivity. Therefore, the operator may arbitrarily set the priority order for using the FPD 3 by using imaging order information other than the recommended detector size and sensitivity (for example, the size of the subject / region of interest and the imaging region).

  The display unit 8 includes a touch panel, a monitor, a television, and the like. In the present embodiment, the FPD 3 selected by the first to third FPD selection units 53 to 55 (see FIG. 2) of the controller 5 to be described later is displayed on the display unit 8 in addition to the flowchart of FIG. 4 to be described later. As shown in the flowchart of FIG. 5, when an FPD 3 having a different size from the recommended detector size is selected, a confirmation dialog (dialog) is displayed on the display unit 8 (step S18 in FIG. 4 or step S27 in FIG. 5). See).

  As shown in FIG. 2, the console 9 includes a controller 5, a memory unit 6, an input unit 7, and a display unit 8 (see also FIG. 1). The controller 5 includes an FPD detection unit 51, an FPD selection unit 52, and first to third FPD selection units 53 to 55. The FPD detection unit 51 corresponds to the X-ray detector detection means in the present invention, the FPD selection unit 52 corresponds to the X-ray detector selection means in the present invention, and the first FPD selection unit 53 corresponds to the first XD in the present invention. The second FPD selection unit 54 corresponds to the line detector selection unit, the second X-ray detector selection unit 54 corresponds to the present invention, and the third FPD selection unit 55 corresponds to the third X-ray detector selection unit of the present invention. .

  A program for performing detection by the FPD detection unit 51, selection by the FPD selection unit 52, selection by the first to third FPD selection units 53 to 55, and the like are written in a storage medium (memory unit 6) represented by a ROM or the like. And the CPU 9 (controller 5) of the console 9 reads the program from the storage medium and executes it, so that detection by the FPD detection unit 51 according to the program, selection by the FPD selection unit 52, and the first to third FPDs Selection is performed by the selection units 53 to 55. In FIG. 1, a control program 6 </ b> A is illustrated in the memory unit 6. The control program 6A corresponds to the control program in the present invention.

  The FPD detection unit 51 detects usable FPD3. In the present embodiment, the detector list information stored in the memory unit 6 as the authenticated FPD 3 is read out and referred to by the FPD detection unit 51 to detect usable FPD 3. The detected FPD 3 is sent to the FPD selection unit 52.

  The FPD selection unit 52 selects the FPD 3 to be selected based on the imaging order information stored in the memory unit 6. In the present embodiment, as described above, the imaging order information is the sensitivity of the FPD 3 in addition to the FPD size (recommended detector size) necessary for the inspection. Then, the FPD selection unit 52 selects the FPD 3 based on the recommended detector size. Further, when considering the sensitivity of the FPD 3, the FPD 3 having the highest sensitivity is selected from the corresponding FPD 3. The information of the selected / selected FPD 3 is sent to the first to third FPD selection units 53 to 55. When there is one usable FPD3, the first FPD selection unit 53 is switched to, and when there are a plurality of usable FPD3, the second FPD selection unit 54 is switched to the same size as the recommended detector size. When the FPD 3 is not usable (that is, when a detector having the same size as the recommended detector size is not included in the detector list information), the FPD 3 is switched to the third FPD selection unit 55.

  When there is one usable FPD 3 of the same size that matches the recommended detector size, the first FPD selection unit 53 selects the corresponding FPD 3 as shown in the flowchart of FIG. (See step S6). In addition, when considering sensitivity, if there is one FPD 3 having the highest sensitivity among usable FPDs 3 of the same size that matches the recommended detector size, the first FPD selection unit 53 will be described later. 3, the corresponding FPD 3 is selected (see step S 9 in FIG. 3).

  When an FPD3 having the same size as the recommended detector size is not usable and an FPD3 having a size larger than the recommended detector size is usable, the FPD3 having a size larger than the recommended detector size is the most. When there is one small size FPD 3, the first FPD selection unit 53 selects the corresponding FPD 3 as shown in a flowchart of FIG. 4 to be described later (see step S13 of FIG. 4). Further, when considering sensitivity, if the FPD 3 having the highest sensitivity of the smallest size is one among the FPDs 3 having a size larger than the recommended detector size, the first FPD selection unit 53 will be described later. The corresponding FPD 3 is selected as shown in the flowchart of FIG. 4 (see step S16 of FIG. 4).

  When the FPD3 having the same size as the recommended detector size cannot be used, the FPD3 having a size larger than the recommended detector size cannot be used, and the FPD3 having a size smaller than the recommended detector size can be used. In FIG. 5, when there is one FPD 3 having the largest size among the FPDs 3 having a size smaller than the recommended detector size, the first FPD selecting unit 53 selects the corresponding FPD 3 as shown in a flowchart of FIG. Is selected (see step S22 in FIG. 5). Further, when considering sensitivity, when the FPD 3 having the highest sensitivity of the largest size is one among the FPDs 3 having a size smaller than the recommended detector size, the first FPD selection unit 53 will be described later. The corresponding FPD 3 is selected as shown in the flowchart of FIG. 5 (see step S25 of FIG. 5).

  When there are a plurality of usable FPDs 3 of the same size that match the recommended detector size, the second FPD selection unit 54 selects the input unit 7 from among the FPDs 3 corresponding to the plurality as shown in the flowchart of FIG. The FPD 3 having the highest priority set in (1) is selected (see step S7 and step S10 in FIG. 3).

  When an FPD3 having the same size as the recommended detector size is not usable and an FPD3 having a size larger than the recommended detector size is usable, the FPD3 having a size larger than the recommended detector size is the most. When there are a plurality of small-sized FPDs 3, the second FPD selection unit 54 selects the FPD 3 having the highest priority set by the input unit 7 from the FPDs 3 as shown in the flowchart of FIG. (See step S14 and step S17 in FIG. 4).

  When the FPD3 having the same size as the recommended detector size cannot be used, the FPD3 having a size larger than the recommended detector size cannot be used, and the FPD3 having a size smaller than the recommended detector size can be used. 2, when there are a plurality of FPDs 3 having the largest size among the FPDs 3 having a size smaller than the recommended detector size, the second FPD selection unit 54 inputs from the FPD 3 as shown in the flowchart of FIG. 5 to be described later. The FPD 3 having the highest priority set in the unit 7 is selected (see step S23 and step S26 in FIG. 5).

  When the FPD3 having the same size as the recommended detector size is not usable, the third FPD selection unit 55 selects the FPD3 as follows. When the FPD 3 having a size larger than the recommended detector size can be used, the third FPD selecting unit 55 selects the smallest FPD 3 from the corresponding large FPDs 3 as shown in a flowchart of FIG. Is selected (see step S11 in FIG. 4). When the FPD 3 having a size larger than the recommended detector size cannot be used and the FPD 3 having a size smaller than the recommended detector size can be used, the third FPD selection unit 55 displays the flowchart shown in FIG. As shown, the largest FPD 3 is selected from the corresponding small FPDs 3 (see step S21 in FIG. 5). When the FPD 3 selected by the third FPD selection unit 55 is further selected based on the imaging order information, it is sent to the FPD selection unit 52.

  The FPD 3 selected by the first to third FPD selection units 53 to 55 is sent to the display unit 8 in order to be explicitly displayed.

  Next, each flowchart of the control related to selection will be described with reference to FIGS. FIG. 3 is a flowchart according to an embodiment when a flat panel X-ray detector (FPD) having the same size as the recommended detector can be used, and FIG. 4 is a flat having the same size as the recommended detector size. FIG. 5 is a flowchart according to an embodiment when a panel type X-ray detector (FPD) is not usable and a flat panel type X-ray detector (FPD) having a size larger than the recommended detector size is usable; In FIG. 5, a flat panel X-ray detector (FPD) having the same size as the recommended detector size cannot be used, and a flat panel X-ray detector (FPD) larger than the recommended detector size can be used. 6 is a flowchart according to an embodiment when a flat panel X-ray detector (FPD) having a size smaller than the recommended detector size is usable.

  3 to 5, the FPD 3 that can be used (see FIGS. 1 and 2) when the imaging order in step S <b> 1 in FIG. 3 is selected (that is, imaging is started based on certain imaging order information). The number of times (see) increases or decreases, or a failure or re-shooting is performed. First, the flowchart of FIG. 3 will be described.

(Step S1) Shooting Order Selection The operator selects from the shooting order information stored in the memory unit 6 (see FIGS. 1 and 2). The selected imaging order is read from the memory unit 6 and sent to the FPD selection unit 52 (see FIG. 2).

(Step S2) Checking usable FPD The detector list information stored in the memory unit 6 is read and the FPD detecting unit 51 (see FIG. 2) refers to it to detect the usable FPD 3. This detection is also called “list-up”, and the usable FPD3 is checked by detecting the usable FPD3. The check result is sent to the FPD selection unit 52. This step S2 corresponds to the X-ray detector detection step in the present invention.

(Step S3) Check Recommended Detector Size The recommended detector size associated with the imaging order information selected in step S1 is checked. Since the imaging order information is the recommended detector size, the FPD selection unit 52 selects the FPD 3 that matches the recommended detector size. At this time, it is preferable to select a usable FPD 3 that does not match the recommended detector size. This step S3 corresponds to the X-ray detector selection step in the present invention.

(Step S4) Can an FPD of the same size as the recommended detector size be used?
It is determined whether or not an FPD 3 having the same size as the recommended detector size can be used. When the FPD 3 having the same size as the recommended detector size is not usable (see “No” in FIG. 3), the FPD 3 is switched to the third FPD selection unit 55 (see FIG. 2) based on the result in step S3. Proceed to step S11 in FIG. When the FPD 3 having the same size as the recommended detector size can be used (see “Yes” in FIG. 3), the process proceeds to step S5.

(Step S5) Are multiple FPDs applicable?
When the FPD 3 having the same size as the recommended detector size is usable, it is determined whether or not there are a plurality of usable FPDs 3. When the number of usable FPDs 3 is one (see “No” in FIG. 3), the FPD 3 is switched to the first FPD selection unit 53 (see FIG. 2), and the process proceeds to step S6. If there are a plurality of usable FPDs 3 (see “Yes” in FIG. 3), the process proceeds to step S7 or step S8.

  When the sensitivity of the FPD 3 is not considered, the second FPD selection unit 54 (see FIG. 2) is switched to and the process proceeds to step S7. When considering the sensitivity of the FPD 3, the process proceeds to step S8. As a setting of the apparatus, a setting as to whether or not sensitivity is taken into consideration is performed in advance, and automatically proceeds to the branch destination based on the set value. Of course, on the display unit 8 (see FIGS. 1 and 2), for example, “Do you consider sensitivity?” And “Do you consider sensitivity?” Buttons or “Do you consider sensitivity?” On the other hand, “Yes” and “No” buttons are displayed, and by clicking any of these buttons with the pointing device of the input unit 7, it is possible to select whether to consider sensitivity or not. Good.

(Step S6) Selecting the Applicable FPD When there is one usable FPD 3, the first FPD selecting unit 53 selects the corresponding FPD 3. In order to explicitly display the FPD 3 selected by the first FPD selection unit 53, the FPD 3 is sent to the display unit 8 to complete a series of detector selections.

(Step S7) Select FPD with Highest Priority Order When the sensitivity of FPD3 is not taken into account and there are a plurality of usable FPD3, the second FPD selection unit 54 selects an input unit from among the FPD3 corresponding to the plurality The FPD 3 with the highest priority set in 7 is selected. In order to explicitly display the FPD 3 selected by the second FPD selection unit 54, the FPD 3 is sent to the display unit 8 and a series of detector selections is completed.

(Step S8) Are there multiple FPDs with the highest sensitivity?
When considering the sensitivity of the FPD 3 and there are a plurality of usable FPDs 3, it is determined whether or not there are a plurality of FPDs 3 having the highest sensitivity among the FPDs 3 corresponding to the plurality. When there is one FPD 3 with the highest sensitivity that can be used (see “No” in FIG. 3), the first FPD selection unit 53 is switched to, and the process proceeds to step S9. When there are a plurality of FPDs 3 having the highest usable sensitivity (see “Yes” in FIG. 3), the process switches to the second FPD selection unit 54 and proceeds to step S10.

(Step S9) Selecting the Applicable FPD When considering the sensitivity of the FPD 3 and when there is one FPD 3 having the highest usable sensitivity, the first FPD selecting unit 53 selects the corresponding FPD 3. In order to explicitly display the FPD 3 selected by the first FPD selection unit 53, the FPD 3 is sent to the display unit 8 to complete a series of detector selections.

(Step S10) Select FPD with the highest priority When considering the sensitivity of FPD3 and when there are a plurality of FPD3 with the highest available sensitivity, the second FPD selection unit 54 selects the FPD3 corresponding to the plurality of FPD3. The FPD 3 having the highest priority set by the input unit 7 is selected from the inside. In order to explicitly display the FPD 3 selected by the second FPD selection unit 54, the FPD 3 is sent to the display unit 8 and a series of detector selections is completed.

  Next, the flowchart of FIG. 4 will be described. If the FPD 3 having the same size as the recommended detector size is not usable in step S4 in FIG. 3 (in the case of “No”), the process proceeds to step S11 in FIG.

(Step S11) Is an FPD larger than the recommended detector size usable?
It is determined whether an FPD 3 having a size larger than the recommended detector size can be used. When the FPD 3 having a size larger than the recommended detector size is not usable (see “No” in FIG. 4), the process proceeds to step S21 in FIG. When the FPD 3 having a size larger than the recommended detector size is usable (see “Yes” in FIG. 4), the process proceeds to step S12.

(Step S12) Are there multiple FPDs with the smallest size?
If an FPD 3 having a size larger than the recommended detector size is usable, it is determined whether or not there are a plurality of FPDs 3 having the smallest size among the corresponding FPDs 3. If there is one smallest FPD 3 (see “No” in FIG. 4), the process proceeds to step S13. When there are a plurality of smallest FPDs 3 (see “Yes” in FIG. 4), the process proceeds to step S14 or step S15.

  If the sensitivity of the FPD 3 is not considered, the process proceeds to step S14. When considering the sensitivity of the FPD 3, the process proceeds to step S15.

(Step S13) Selecting the Applicable FPD When the smallest FPD3 is one, the first FPD selecting unit 53 selects the corresponding FPD3. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S18 in order to display a confirmation dialog.

(Step S14) Select FPD with Highest Priority Order When the sensitivity of FPD3 is not taken into consideration and there are a plurality of smallest FPD3, the second FPD selection unit 54 selects the input unit 7 from among the FPD3 corresponding to the plurality. The FPD 3 having the highest priority set in step 1 is selected. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S18 in order to display a confirmation dialog.

(Step S15) Are there multiple FPDs with the highest sensitivity?
When considering the sensitivity of the FPD 3 and when there are a plurality of smallest FPDs 3, it is determined whether or not there are a plurality of FPDs 3 having the highest sensitivity among the FPDs 3 corresponding to the plurality. If there is one FPD 3 with the highest sensitivity (see “No” in FIG. 4), the process proceeds to step S16. If there are a plurality of FPDs 3 having the highest sensitivity (see “Yes” in FIG. 4), the process proceeds to step S17.

(Step S <b> 16) Selecting the Applicable FPD When considering the sensitivity of the FPD 3 and when there is one FPD 3 having the highest sensitivity, the first FPD selection unit 53 selects the corresponding FPD 3. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S18 in order to display a confirmation dialog.

(Step S17) Select FPD with Highest Priority Order When considering the sensitivity of FPD3 and when there are a plurality of FPD3 with the highest sensitivity, the second FPD selection unit 54 inputs from among FPD3 corresponding to the plurality of FPD3 The FPD 3 having the highest priority set in the section 7 is selected. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S18 in order to display a confirmation dialog.

(Step S18) Displaying Confirmation Dialog Since FPD3 selected in Step S13, Step S14, Step S16 or Step S17 is FPD3 of a size different from the recommended detector size, a confirmation dialog is displayed on display unit 8. . The display mode of the confirmation dialog is not particularly limited. For example, a confirmation dialog such as “An FPD of a recommended detector size cannot be used, so another size FPD was selected. Check the currently selected FPD”. Is displayed. After the confirmation dialog is displayed, the series of detector selection is finished. This confirmation dialog is not necessarily displayed but may be displayed or may not be displayed.

  Next, the flowchart of FIG. 5 will be described. If the FPD 3 having a size larger than the recommended detector size is not usable at step S11 in FIG. 4 (“No”), the process proceeds to step S21 in FIG.

(Step S21) Are there multiple FPDs having the largest size?
If an FPD 3 having a size smaller than the recommended detector size is usable, it is determined whether or not there are a plurality of FPDs 3 having the largest size among the corresponding FPDs 3. If there is one largest FPD3 (see “No” in FIG. 5), the process proceeds to step S22. When there are a plurality of the largest FPDs 3 (see “Yes” in FIG. 5), the process proceeds to step S23 or step S24.

  If the sensitivity of the FPD 3 is not considered, the process proceeds to step S23. When considering the sensitivity of the FPD 3, the process proceeds to step S24.

(Step S22) Selecting the Applicable FPD When there is one largest FPD3, the first FPD selecting unit 53 selects the corresponding FPD3. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S27 in order to display a confirmation dialog.

(Step S23) Select FPD with Highest Priority Order When the sensitivity of FPD3 is not taken into account and there are a plurality of largest FPD3, the second FPD selection unit 54 selects the input unit 7 from among the FPD3 corresponding to the plurality. The FPD 3 having the highest priority set in step 1 is selected. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S27 in order to display a confirmation dialog.

(Step S24) Are there multiple FPDs with the highest sensitivity?
When considering the sensitivity of the FPD 3 and when there are a plurality of the largest FPDs 3, it is determined whether or not there are a plurality of FPDs 3 having the highest sensitivity among the FPDs 3 corresponding to the plurality. If there is one FPD 3 with the highest sensitivity (see “No” in FIG. 5), the process proceeds to step S25. If there are a plurality of FPDs 3 having the highest sensitivity (see “Yes” in FIG. 5), the process proceeds to step S26.

(Step S25) Selecting the Applicable FPD When considering the sensitivity of the FPD 3 and when there is one FPD 3 having the highest sensitivity, the first FPD selecting unit 53 selects the corresponding FPD 3. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S27 in order to display a confirmation dialog.

(Step S26) Select FPD with Highest Priority Order When considering the sensitivity of FPD3 and when there are a plurality of FPD3 with the highest sensitivity, the second FPD selection unit 54 inputs from among FPD3 corresponding to the plurality of FPD3 The FPD 3 having the highest priority set in the section 7 is selected. Here, since the FPD 3 having a size different from the recommended detector size is selected, the process proceeds to step S27 in order to display a confirmation dialog.

(Step S27) Display Confirmation Dialog The FPD3 selected in Step S22, Step S23, Step S25 or Step S26 is an FPD3 of a size different from the recommended detector size, and therefore a confirmation dialog is displayed on the display unit 8. . As described in step S18 in FIG. 4, the display mode of the confirmation dialog is not particularly limited. After the confirmation dialog is displayed, the series of detector selection is finished. As described in step S18 of FIG. 4, the confirmation dialog is not necessarily displayed, and may be displayed or may not be displayed.

  According to the X-ray imaging apparatus according to the present embodiment, X-ray detector detection means (FPD detection unit 51 in the present embodiment) for detecting usable X-ray detectors (FPD 3 in the present embodiment), and inspection order. X-ray detector selection means (FPD selection unit 52 in this embodiment) for selecting an X-ray detector (FPD3) to be selected based on information (imaging order information in this embodiment) is provided. And X-ray detector selection means (FPD selection section) based on examination order information (imaging order information) among X-ray detectors (FPD3) detected by the X-ray detector detection means (FPD detection section 51). 52), the X-ray detector (FPD3) is selected. In this way, since the corresponding X-ray detector (FPD3) is selected based on the inspection order information (imaging order information) among the usable X-ray detectors (FPD3), the inspection (imaging in this embodiment) is performed. The usable X-ray detector (FPD3) dynamically changes at the timing of execution (in this embodiment, the X-ray imaging device for round trips is moved by the mobile carriage 1 and the peripheral X-ray sharing the FPD3. When there is a possibility that the imaging apparatus changes dynamically, an X-ray detector FPD3 suitable for the purpose (of the imaging order) is automatically selected from the available X-ray detectors (FPD3). Can do. As a result, it is possible to reduce the burden on the operator during the inspection operation (in the present embodiment, during the photographing operation).

  Here, as a case where the X-ray imaging apparatus for round trips is moved by the mobile carriage 1 and the peripheral X-ray imaging apparatuses sharing the X-ray detector (FPD 3) dynamically change, for example, as follows: There are cases. As described above, when there is an X-ray detector (FPD3) that is shared and used by a plurality of devices such as the devices A and B, the X-ray detector (FPD3) is “used by the device A”. When the state is changed from “Available state” to “A state that can be used by the device B”, it dynamically changes as follows. That is, by deleting the corresponding X-ray detector (FPD3) from the detector list information from the device A, the number of usable X-ray detectors (FPD3) is reduced. By authenticating the line detector (FPD3), the number of usable X-ray detectors (FPD3) increases.

  In this embodiment, the inspection order information (imaging order information) is an X-ray detector size (recommended detector size) necessary for inspection, and the X-ray detector selection means (FPD selection unit 52) performs the recommended detection. X-ray detector (FPD3) is selected based on the size of the instrument. When an X-ray detector (FPD3) of the same size that matches the recommended detector size can be used, the X-ray detector (FPD3) of the same size can be selected. In particular, as described in step S5 of FIG. 3, when there is one X-ray detector (FPD3) of the same size, the corresponding X-ray detector (FPD3) is selected as in step S6. To do.

  Moreover, usable X-rays among the X-ray detector (FPD3) selected by the X-ray detector selection means (FPD selection unit 52) including the recommended detector size and other sizes other than the recommended detector size. When there is one detector (FPD3), the corresponding X-ray detection is performed as shown in steps S6 and S9 in FIG. 3, steps S13 and S16 in FIG. 4, and steps S22 and S25 in FIG. First X-ray detector selection means (first FPD selection unit 53 in this embodiment) for selecting the detector (FPD3).

  In this embodiment, when there are a plurality of usable X-ray detectors (FPD3) including the recommended detector size and other sizes other than the recommended detector size, the X-ray detector (FPD3) An operator manually sets the priority order to use the X-ray detector (FPD3) according to the priority order. That is, according to the priority order setting means (input unit 7 in this embodiment) for setting the priority order for using the X-ray detector (FPD3) and the priority order set by the priority order setting means (input section 7). Second X-ray detector selection means (second FPD selection unit 54 in this embodiment) for selecting the X-ray detector (FPD3). In this case, there are a plurality of X-ray detectors (FPD3) including the same size or different sizes among the X-ray detectors (FPD3) detected by the X-ray detector detection means (FPD detection unit 51). The second X-ray detector selection means (second FPD selection section 54) is set by the priority setting means (input section 7) from among a plurality of X-ray detectors (FPD3). The X-ray detector (FPD3) having the highest priority is selected as in step S7 or step S10 in FIG. 3, step S14 or step S17 in FIG. 4, or step S23 or step S26 in FIG.

  In the case where the inspection order information (imaging order information) is the recommended detector size as in this embodiment, an X-ray detector (FPD3) of the same size that matches the recommended detector size can be used, and FIG. As described in step S5, when there are a plurality of the same size X-ray detectors (FPD3), the plurality of the same size X-ray detectors (FPD3) corresponding to the plurality are used as in steps S7 and S10. The X-ray detector (FPD3) having the highest priority is selected from the above.

  In the case where the inspection order information (imaging order information) is the recommended detector size as in the present embodiment, the third X-ray detector selection means (the third FPD selection section 55 in the present embodiment) that performs the selection as described above is provided. I have. That is, when an X-ray detector (FPD3) having the same size as the recommended detector can be used (“Yes” in step S4 in FIG. 3), the third X-ray detector selection means (third FPD selection) The unit 55) selects the same size X-ray detector (FPD3). On the other hand, an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used (see “No” in step S4 in FIG. 3), and an X-ray detection size larger than the recommended detector size is detected. When the detector (FPD3) is usable (in the case of “Yes” in step S11 of FIG. 4), the third X-ray detector selection means (third FPD selection unit 55) detects the corresponding large-sized X-ray. The smallest X-ray detector (FPD3) is selected from the detector (FPD3). If an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used and an X-ray detector (FPD3) having a size larger than the recommended detector size can be used, As described in the section “Problems to be solved” and “Means for solving the problems”, if an X-ray detector (FPD3) having a size larger than the recommended detector size is selected, inspection (this embodiment) Then, it is possible to cover the range of the X-ray detector (FPD3) necessary for imaging). On the other hand, considering the need to use as small an X-ray detector as possible, the smallest X-ray detector (FPD3) should be selected from the corresponding large X-ray detectors (FPD3). Thus, it is possible to cover the range of the X-ray detector necessary for the inspection (imaging) (range of the region of the imaging region) while meeting the above needs.

  Furthermore, an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used (see “No” in step S4 in FIG. 3), and an X-ray detector having a size larger than the recommended detector size. If (FPD3) is not usable (see “No” in step S11 of FIG. 4) and an X-ray detector (FPD3) having a size smaller than the recommended detector size is usable, The 3 X-ray detector selection means (third FPD selection unit 55) selects the X-ray detector (FPD3) having the largest size from the corresponding X-ray detectors (FPD3) having a small size. As a result, an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used, and an X-ray detector (FPD3) having a size larger than the recommended detector size cannot be used. The X-ray detector (FPD3) having the largest size among the corresponding X-ray detectors (FPD3) having a smaller size than the recommended detector size is selected as the X-ray detector size (recommended detector) required for the inspection. It can be used as an X-ray detector (FPD3) having a size as close as possible to (size).

  Further, in this embodiment, the inspection order information (imaging order information) is the sensitivity of the X-ray detector (FPD3) in addition to the recommended detector size described above, and is an X-ray detector detection means (FPD detection unit). 51) Among the X-ray detectors (FPD3) detected in 51), the X-ray detector selection means (FPD selection unit 52) selects an X-ray detector (FPD3) that can be used based on the recommended detector size. Based on the line detector (FPD3), the X-ray detector (FPD3) having the highest sensitivity is selected from the corresponding X-ray detectors (FPD3). When the X-ray detector (FPD3) is automatically selected based on the sensitivity of the X-ray detector (FPD3) as in this embodiment, “available FPD3” → “recommended detector size” → “ The X-ray detector (FPD3) is automatically selected in the order of “sensitivity of FPD3” → “FPD3 having the highest sensitivity”. As a result, the X-ray detector (FPD3) having the highest usable sensitivity among the X-ray detectors (FPD3) selected based on the recommended detector size can be used. The irradiation dose can be reduced, leading to a reduction in exposure of the subject (patient).

  Even when the X-ray detector (FPD3) is automatically selected based on the sensitivity of the X-ray detector (FPD3), the recommended detector size and other sizes other than the recommended detector size can be used. When there is one X-ray detector (FPD3) having the highest sensitivity, the first X-ray detector selection means (first FPD selection unit 53) performs step S9 in FIG. 3, step S16 in FIG. The corresponding X-ray detector (FPD3) is selected as in step S25 of FIG.

  In addition, when the X-ray detector (FPD3) is automatically selected based on the sensitivity of the X-ray detector (FPD3), the recommended detector size and other sizes other than the recommended detector size are used. When there are a plurality of X-ray detectors (FPD3) having the highest possible sensitivity, the priority order for using the X-ray detector (FPD3) is manually set by the operator as described above, and the priority order is set. The X-ray detector (FPD3) is automatically selected according to the above. That is, similarly, the priority order setting means (input unit 7) sets the priority order for using the X-ray detector (FPD3), and the second X-ray detector selection means (second FPD selection unit 54) The X-ray detector (FPD3) is selected according to the priority set by the rank setting means (input unit 7). In this case, it is useful when there are a plurality of X-ray detectors (FPD3) having the highest usable sensitivity, such as step S8 in FIG. 3, step S15 in FIG. 4, and step S24 in FIG. The second X-ray detector selecting means (second FPD selecting section 54) has the highest priority set by the priority setting means (input section 7) among a plurality of X-ray detectors (FPD3). The detector (FPD3) is selected as shown in step S10 in FIG. 3, step S17 in FIG. 4, and step S26 in FIG.

  Even when the X-ray detector (FPD3) is automatically selected based on the sensitivity of the X-ray detector (FPD3), the third X-ray detector selection means (third FPD selection unit 55) performs the selection as described above. Do. That is, when an X-ray detector (FPD3) having the same size as the recommended detector can be used (“Yes” in step S4 in FIG. 3), the third X-ray detector selection means (third FPD selection) The unit 55) selects the same size X-ray detector (FPD3). On the other hand, an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used (see “No” in step S4 in FIG. 3), and an X-ray detection size larger than the recommended detector size is detected. When the detector (FPD3) is usable (in the case of “Yes” in step S11 of FIG. 4), the third X-ray detector selection means (third FPD selection unit 55) detects the corresponding large-sized X-ray. The smallest X-ray detector (FPD3) is selected from the detector (FPD3). Furthermore, it corresponds based on the X-ray detector (FPD3) which can be used among the X-ray detectors (FPD3) of the smallest size selected by the said 3rd X-ray detector selection means (3rd FPD selection part 55). The X-ray detector (FPD3) having the highest sensitivity is selected from the X-ray detectors (FPD3). By selecting the smallest X-ray detector (FPD3) from the corresponding large X-ray detector (FPD3), inspection (imaging) while responding to the need to use the smallest X-ray detector as much as possible. The range of the X-ray detector (range of the region to be imaged) necessary for (1) can be covered. Furthermore, by selecting the X-ray detector (FPD3) having the highest sensitivity from among a plurality of X-ray detectors (FPD3) having the same size, the X-ray having the highest sensitivity that can be used while meeting the above needs. The detector (FPD3) can be used, and the higher the sensitivity, the lower the X-ray irradiation dose, leading to a reduction in the exposure of the subject (patient).

  Even when the X-ray detector (FPD3) is automatically selected based on the sensitivity of the X-ray detector (FPD3), the third X-ray detector selection means (third FPD selection unit 55) performs the selection as described above. Do. That is, an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used (see “No” in step S4 in FIG. 3), and an X-ray detector having a size larger than the recommended detector size. If (FPD3) is not usable (see “No” in step S11 of FIG. 4) and an X-ray detector (FPD3) having a size smaller than the recommended detector size is usable, The 3 X-ray detector selection means (third FPD selection unit 55) selects the X-ray detector (FPD3) having the largest size from the corresponding X-ray detectors (FPD3) having a small size. And it corresponds based on the X-ray detector (FPD3) which can be used among the X-ray detectors (FPD3) of the largest size selected by the said 3rd X-ray detector selection means (3rd FPD selection part 55). The X-ray detector (FPD3) having the highest sensitivity is selected from the X-ray detectors (FPD3). As a result, an X-ray detector (FPD3) having the same size as the recommended detector size cannot be used, and an X-ray detector (FPD3) having a size larger than the recommended detector size cannot be used. The X-ray detector (FPD3) having the largest size among the corresponding X-ray detectors (FPD3) having a smaller size than the recommended detector size is selected as the X-ray detector size (recommended detector) required for the inspection. It can be used as an X-ray detector (FPD3) having a size as close as possible to (size). Furthermore, the X-ray detector (FPD3) having the highest usable sensitivity can be used, and the higher the sensitivity, the lower the X-ray irradiation dose, leading to a reduction in the exposure of the subject (patient).

  In this embodiment, the present invention is applied to an X-ray imaging apparatus for round visits having a mobile carriage, so that the X-ray imaging apparatus for round trips is moved by the mobile carriage 1 and the X-ray imaging around FPD 3 is shared. Even when the apparatus dynamically changes, an X-ray detector (FPD3) suitable for the purpose (of the imaging order) can be automatically selected from the available X-ray detectors (FPD3).

  Further, in the X-ray imaging apparatus for round trips, there is no imaging in a state where the X-ray detector (FPD3) is incorporated in the Bucky apparatus unlike the general imaging apparatus. If radiography is performed in a state where it is incorporated in the Bucky device, the X-ray detector (FPD3) in the Bucky device may be automatically selected as the X-ray detector (FPD3) used for radiography. If this is not the case (when imaging is performed using an X-ray imaging apparatus for round visits as in this embodiment), it is necessary to designate the X-ray detector (FPD3) used for imaging by some method. For this reason, in many cases, an X-ray detector (FPD3) used for radiographing must be selected in an X-ray radiographing device for round visits compared to radiographing with a general radiographing device. Even if the X-ray detector (FPD3) in the Bucky device is selected without permission in the case of imaging (Bucky imaging) in a state incorporated in the Bucky device, it is unlikely that this is an inappropriate selection result. When there is no definitive information for selecting a detector such as a bucky device, it is necessary to select the X-ray detector (FPD3) with other information. In addition, in the present embodiment, since the target X-ray detector (FPD3) is not always the same as the target X-ray detector (FPD3), the X-ray detector (FPD3) is used in some way. Even if it is selected, there is a high possibility that it is an inappropriate selection result. In summary, in the case of imaging in a state where it is incorporated in the Bucky device, the X-ray detector (FPD3) is inappropriately selected due to the limitation of the X-ray detector (FPD3) used for imaging. Less likely. On the other hand, in the case of imaging that is not incorporated in a Bucky device, such as a round-trip X-ray imaging apparatus, there is no restriction on the X-ray detector (FPD3) used for imaging, and therefore the X-ray detector (FPD3). ) Is likely to be selected inappropriately.

  Therefore, in this embodiment, the present invention is applied to an X-ray imaging apparatus for round trips having a mobile carriage, so that even in a situation where there is no such restriction, from among usable X-ray detectors (FPD3) ( An X-ray detector (FPD3) suitable for the purpose (of the imaging order) can be automatically selected. Thus, the present invention is useful for an X-ray imaging apparatus for round visits as in this embodiment.

  In the present embodiment, the case where the same X-ray detector (FPD3) is shared by a plurality of round-trip X-ray imaging apparatuses has been described. However, the X-ray detector (FPD3) is incorporated in the Bucky device. It should be noted that there may be a case where the surrounding X-ray imaging apparatus sharing the X-ray detector (FPD3) dynamically changes. For example, a case in which the same X-ray detector (FPD3) is shared by a roundabout X-ray imaging apparatus and a stationary X-ray imaging apparatus, or the same X-ray detector is shared by a plurality of stationary X-ray imaging apparatuses Even in the case of sharing (FPD3), there may be a case where the surrounding X-ray imaging apparatuses sharing the X-ray detector (FPD3) change dynamically. However, in the X-ray imaging apparatus for round trips as in the present embodiment, the peripheral X-ray imaging apparatus sharing the X-ray detector (FPD3) changes dynamically as the apparatus itself moves. Can occur. For example, the communication setting of the device / X-ray detector (FPD3) remains “communication setting”, but the distance between the device and the X-ray detector (FPD3) is increased as a result of the movement of the device. There may be a case where radio waves cannot be detected, and as a result, they are not considered as usable X-ray detectors (FPD3). Even if such a case occurs, the X-ray detector (FPD3) suitable for the purpose (of the radiographing order) can be selected from the available X-ray detectors (FPD3) without depending on the reception status of radio waves. Can be selected automatically.

  In this embodiment, as a method of disabling the usable X-ray detector (FPD3), a method in which the operator explicitly changes the setting to an unusable setting (in this embodiment, an authentication operation). However, the method is not limited to this. As described in the authentication operation in the present embodiment, when the X-ray detector is of a wireless type, for example, by moving the usable X-ray detector (FPD3) out of the radio wave range, “cannot communicate. The X-ray detector (FPD3) that can be used as a trigger may be treated as an unusable X-ray detector (FPD3). When such an operation is performed, on the contrary, the X-ray detector (FPD3) which cannot be used as a trigger when the distance between the apparatus and the X-ray detector (FPD3) is close and the radio wave can be detected. ) May be handled as a usable X-ray detector (FPD3).

  However, considering the case where it is unclear to which device the X-ray detector (FPD3) is associated as long as it operates wirelessly, “the device and the X-ray detector are at a distance where radio waves can be detected. It is preferable not to set that the X-ray detector (FPD3) can be used only under the condition that “is located”. That is, on the premise that an X-ray detector (FPD3) is associated with a certain device, the X-ray detector as viewed from the device using the distance between the above-described device and the X-ray detector (FPD3) as a trigger. (FPD3) is set to be usable or not usable. For example, when the device A is associated with the detector a and the device B that is not associated with the device A exists in the vicinity of the detector a and the device A is moved away from the detector a, the device A May consider detector a unusable. However, the detector a does not connect with the device B, and the detector a continues to try to connect with the device A. That is, the detector a remains in an unusable state when viewed from the device B that is not associated. Thereafter, when the device A is moved closer to the detector a, the device A considers that the detector a can be used. As described above, when the distance between the apparatus and the X-ray detector (FPD3) is used as a trigger, it may be set that the X-ray detector (FPD3) cannot be used when the distance increases. When approaching, it is set that the X-ray detector (FPD 3) can be used only for the associated apparatus.

  In the control method according to the present embodiment, an X-ray detector detection step (step S2) for detecting an available X-ray detector (FPD3) and a selection target based on examination order information (imaging order information). Of the X-ray detector (FPD3) detected in the X-ray detector detection step (step S2). The X-ray detector (FPD3) selected in the X-ray detector selection step (step S3) is selected.

  Further, in the control program 6A shown in FIG. 1, an X-ray detector detection step (step S2) for detecting an available X-ray detector (FPD3) and an object to be selected based on examination order information (imaging order information) Of the X-ray detector (FPD3) detected in the X-ray detector detection step (step S2). The X-ray detector (FPD3) selected in the X-ray detector selection step (step S3) is selected, and the processing in these steps is executed by a computer (CPU of the controller 5 in this embodiment).

  Further, according to the controller 5, the control method, and the control program 6A according to the present embodiment, usable X-ray detection (detected by the FPD detection unit 51) can be performed as in the X-ray imaging apparatus according to the present embodiment. Since the corresponding X-ray detector (FPD3) is selected on the basis of the inspection order information (imaging order information) among the detectors (FPD3), the X-ray detector (FPD3) usable at the timing of performing the inspection (imaging) Automatically select an X-ray detector (FPD3) suitable for the purpose (of the imaging order) from among the available X-ray detectors (FPD3). it can.

  The present invention is not limited to the above-described embodiment, and can be modified as follows.

  (1) In the above-described embodiments, imaging has been described as an example of inspection in an X-ray apparatus. However, the present invention is applied to fluoroscopy in which an X-ray image is displayed in real time while irradiating a weaker dose of X-rays than imaging. Also good. Further, the present invention may be applied to tomography such as tomosynthesis and X-ray CT (Computed Tomography), and to long imaging in which X-ray images are connected in the longitudinal direction of a subject to obtain a long image. .

  (2) In the above-described embodiments, the X-ray imaging apparatus for round trips having a mobile carriage as the X-ray apparatus has been described as an example. However, a stationary X-ray apparatus may be used. As a stationary X-ray apparatus, for example, an X-ray apparatus that is fixedly installed on a floor surface or a ceiling surface and inspected in a lying position, or an X-ray apparatus that is fixedly installed on a wall surface and inspected in a standing position is used. is there.

  (3) A combination of X-ray apparatuses sharing an X-ray detector is not particularly limited. A combination of round X-ray apparatuses as in the above-described embodiments, a combination of a round X-ray apparatus and a stationary X-ray apparatus, or a stationary X-ray apparatus may be used. A combination of line devices may be used.

  (4) In the above-described embodiment, a flat panel X-ray detector (FPD) that is a digital X-ray detector capable of communication with the console is used as the X-ray detector. Is not particularly limited. An analog X-ray detector may be used as exemplified by an image intensifier (II) or an X-ray film.

  (5) In the embodiment described above, the inspection order information (imaging order information in the embodiment) is the recommended detector size and the sensitivity of the X-ray detector (FPD3 in the embodiment), and the X-ray detector selection means ( In the embodiment, the FPD selection unit 52) selects the X-ray detector (FPD3) based on the recommended detector size, but the inspection order information (imaging order information) is the recommended detector size or the X-ray detector (FPD3). It is not limited to the sensitivity. For example, the examination order information (imaging order information) may be the size of the subject / region of interest or the imaging region. If the imaging region is rich in variety, such as the limbs and chest, prepare an X-ray detector for limb imaging associated with the limb and an X-ray detector for chest imaging associated with the chest. The X-ray detector may be selected based on the selected imaging region. Also, as in Patent Document 2: Japanese Patent Laid-Open No. 2002-191586, when the inspection order information (imaging order information) is spatial resolution, an X-ray detector associated with each spatial resolution is prepared, In the case of fluoroscopy that does not require high spatial resolution, an X-ray detector having low spatial resolution is selected, and in the case of radiography that requires high spatial resolution, an X-ray detector having high spatial resolution is selected. Select.

  (6) In the above-described embodiment, the priority order is set based on imaging order information other than the recommended detector size and sensitivity (for example, the size of the subject / region of interest and the imaging region). The priority order may be set based on the recommended detector size, or the priority order may be set based on the sensitivity. When setting the priority order based on the sensitivity, the X-ray detector having the highest sensitivity is set to the highest priority order, and the X-ray detector is set to the lower order as the sensitivity becomes lower. As a result, an X-ray detector with high sensitivity can be preferentially used from among usable X-ray detectors, and the higher the sensitivity, the lower the X-ray irradiation dose, and the subject (patient ) Leads to a reduction in exposure. In particular, when there are a plurality of X-ray detectors of the same size that can be used, it is useful for selecting the X-ray detector having the highest priority from among the X-ray detectors of the same size corresponding to the plurality of X-ray detectors. When setting the priority order based on the sensitivity, “available X-ray detector” → “X-ray detector size (recommended detector size)” → “X-ray detector sensitivity” → “priority order” X-ray detectors are selected in the order of "."

  (7) In the above-described embodiment, an X-ray detector (in the embodiment, FPD3 in the embodiment) or an X-ray detector (in the embodiment, FPD3 in the embodiment) that can be selected by the X-ray detector selection means (in the embodiment, FPD selection section 52) or usable. The selection of FPD 3) is performed with priority. However, selection and selection may be performed with priority as in the following modifications (6) to (8) over the selection and the selection.

  (8) For example, a first change setting means for changing and setting the X-ray detector that was in an unusable state to a usable state is provided. The first change setting means (the first change setting unit 56 in FIG. 6) is composed of the communication port and the CPU of the communication means for performing the authentication operation described in the above-described embodiment. As described in the authentication operation in the above-described embodiment, the X-ray detector that is changed and set in a usable state by the first change setting means (first change setting unit 56) is selected with the highest priority. For example, when an X-ray detector is shared by a plurality of X-ray apparatuses, the X-ray detector is used in one X-ray apparatus (apparatus A), and the other X-ray apparatus (apparatus B) uses the X-ray detector. The line detector becomes unusable. When it is desired to use the X-ray detector in the other X-ray apparatus (apparatus B), the other X-ray detector can be changed and set to a usable state by the first change setting means (first change setting unit 56). In the line device (device B), the X-ray detector is selected with the highest priority. Accordingly, in FIG. 6, the first change setting unit 56 is connected to the first to third FPD selection units 53 to 55, and is changed and set to a state usable by the first change setting means (first change setting unit 56). In this case, the X-ray detector is not selected by the first to third FPD selection units 53 to 55, and is changed and set to a usable state by the first change setting means (first change setting unit 56). The X-ray detector is automatically selected with the highest priority. The timing of the authentication operation may not be before the inspection as in the above-described embodiment. For example, it is possible to perform an authentication operation during the inspection. In other words, authenticating an X-ray detector that is not available to the device at the time of the inspection is an interpretation that the device intends to use the X-ray detector now, It is also possible to automatically select the selected X-ray detector with the highest priority.

  (9) Conversely, a second change setting means for changing and setting the X-ray detector that has been selected as the usable X-ray detector to an unusable state may be provided. The second change setting means is constituted by an input unit 7 as shown in FIG. When the second change setting means (input unit 7) changes the setting to an unusable state, the X-ray detector selection means (FPD selection unit 52 in FIG. 7) performs selection again to select the X-ray detector. To do it again. Therefore, in FIG. 7, the input unit 7 is connected to the FPD selection unit 52 and the first to third FPD selection units 53 to 55, and is changed and set to an unusable state by the second change setting means (input unit 7). Then, the selection is performed again by selecting the FPD selecting unit 52 or selecting the X-ray detectors by the first to third FPD selecting units 53 to 55 again. The second change setting unit may not be the input unit 7. For example, as described in the authentication operation in the above-described embodiment, when the X-ray detector is a wireless type, if the usable X-ray detector is moved out of the radio wave range, it is used even if it has been authenticated. By deleting from the available detector list information, the X-ray detector selected as an available X-ray detector may be automatically changed and set to an unusable state. In this case, the wireless LAN communication port and the CPU constitute the second change setting means.

  (10) For example, one X-ray detector among the usable X-ray detectors is selected with the highest priority. For example, if an inspection order that has already been inspected is subjected to a copying operation or an order duplication operation, and a new inspection order is added, the X-ray detector used immediately before re-imaging is performed. If the X-ray detector that is the target of the added inspection order is usable, the X-ray detector may be used by selecting the X-ray detector with the highest priority. . The X-ray detector selected with the highest priority is not limited to the above example as long as it is usable, and one X-ray detector among usable X-ray detectors is selected. The operator can arbitrarily select the highest priority.

  (11) In the embodiment described above, usable X-ray detector (FPD3) among the X-ray detector (FPD3 in the embodiment) selected by the X-ray detector selecting means (FPD selection unit 52 in the embodiment). 1 is provided with first X-ray detector selection means (first FPD selection unit 53 in the embodiment) for selecting the corresponding X-ray detector, but usable X-ray detector (FPD3). ) Always exist, a second X-ray detector selection means (second FPD selection section 54 in the embodiment) may be provided without providing the first X-ray detector selection means (first FPD selection section 53). .

  (12) In the embodiment described above, usable X-ray detector (FPD3) among the X-ray detector (FPD3 in the embodiment) selected by the X-ray detector selecting means (FPD selecting unit 52 in the embodiment). In the case where there are a plurality of devices, priority order setting means (input unit 7 in the embodiment) for setting the priority order for using the X-ray detector is provided, but the priority order need not necessarily be set.

  (13) In the above-described embodiment, when the examination order information (imaging order information) has the recommended detector size, the third X-ray detector selection unit (the third FPD selection unit 55 in the embodiment) is provided. When an X-ray detector (FPD 3 in the embodiment) having a uniform detector size and a variety of sensitivities and spatial resolutions is used, the third X-ray detector selection means (third FPD selection unit 55) is not necessarily used. ) Is not necessary. That is, when the recommended detector size is uniform, the flowcharts of FIGS. 4 and 5 are not necessarily performed.

  (14) In the above-described embodiment, the X-ray detector having the highest sensitivity (FPD3 in the embodiment) is selected when the sensitivity is taken into consideration. When the FPD 3) is used, it is not always necessary to select the X-ray detector (FPD 3) having the highest sensitivity.
