Description

  The present invention relates to an automatic contrast medium injection device and a program.

  Conventionally, radiographic images typified by X-ray images have been widely used for disease diagnosis and the like, and as an apparatus for capturing radiographic images, a device that uses a radiation film as a means for detecting radiation transmitted through a subject, In addition, there is known one using a stimulable phosphor sheet that obtains a visible image using a stimulable phosphor (stimulable phosphor) that accumulates irradiated radiation energy. Furthermore, in recent years, a flat detector called an FPD (Flat Panel Detector) for outputting radiographic image data indicating a detected radiographic image by a plurality of solid-state photodetecting elements arranged in a two-dimensional form. A radiographic imaging apparatus having a kind of the above is sold. In radiography, radiography using a contrast agent has been performed in order to highlight a tissue having a small difference in radiation absorption rate from surrounding tissues. In radiography using such a contrast agent, in addition to X-ray digestive tract imaging, in which a barium contrast agent is swallowed or enema and the digestive organs such as the stomach and intestine are imaged, a contrast agent is injected into the lymphatic vessel. X-ray lymphography, X-ray imaging in which a contrast medium is injected into the urinary tract, uterine fallopian tubes, joints, etc., X-ray angiography in which a contrast medium is injected into a blood vessel There is.

  In X-ray imaging in which a contrast medium is injected into a blood vessel, the contrast medium is mainly injected from a vein and CT imaging is performed, or the excretory organ is imaged when the contrast medium injected from the vein is excreted. There are venous pyelography, and the tip of a catheter is inserted by puncturing an appropriate site, the tip is advanced to the vicinity of the target tissue, a contrast medium is injected in the vicinity of the target tissue, and the target tissue is imaged.

Further, in Patent Document 1, in an X-ray tomography apparatus, an X-ray tube and an X-ray detection unit are incorporated to capture a tomographic image of a subject, and a contrast medium injection device may be incorporated. It is described that a flat detector may be used as the radiation detection means. Since such an apparatus for taking a tomographic image requires expensive driving means for accurately moving the X-ray tube and the X-ray detection means relative to each other, a contrast agent injection device having high durability and durability is also built in. Of course, it is an integral device. Patent Document 2 describes that the CT scanner and the chemical solution injector are separate and interlocked. However, the CT scanner and the chemical solution injector are always interlocked, and there is no description of detecting whether or not they can be interlocked.
Japanese Patent Laid-Open No. 10-295680 JP 2004-298610 A

Therefore, as a result of diligent examination, this is not an expensive integrated device as disclosed in JP-A-10-295680, but a radiation irradiation device such as an X-ray tube, a flat detector, and a contrast medium injection device. It has been found that each is preferably a separate unit.
That is, an integrated apparatus in which such a contrast medium injecting apparatus is built in a radiographic imaging apparatus tends to be expensive, and it is difficult for a small-scale medical institution to introduce such an apparatus. Further, if it is not possible to perform radiographic imaging using a contrast agent without introducing such an expensive device, the cost for performing radiographic imaging using a contrast agent increases, and the medical cost increases. There is also a problem that the burden on the patient increases.

  In view of this, it is possible to configure the radiation irradiation device, the flat detector, and the contrast medium injection device as individual single devices, and perform radiographic imaging using the contrast agent by combining them. By combining a single device in this way, when a contrast agent is not used for imaging, it is possible to use only a combination of a radiation irradiation device and a flat detector, or by combining each device with another device. It can be used for any purpose, or individual devices can be used freely. For this reason, the usable range of the device is widened compared to a single integrated device including a radiation irradiation device, a flat detector, and a contrast medium injection device, and the frequency of use of each device is increased and the device is operated efficiently. Can be made. This makes it possible to reduce the unit price per image.

  This is because, in this way, each device can be used in combination with other devices for other purposes, compared to the case where it is a dedicated integrated device. This is because the possible range is widened, the device is less likely to play, the operation rate of the device is increased, and as a result, the unit price per image can be reduced.

  In addition, these radiation irradiation devices, flat detectors, and contrast medium injection devices have different application ranges and use frequencies for each facility / hospital. In some facilities / hospitals, two radiation irradiation devices and three flat detectors are used. Depending on the facility / hospital, a combination of two contrast medium injection devices, or a combination of a radiation irradiation device, a flat detector, and a contrast medium injection device may be used.

  When there are a plurality of one type of devices in a facility / hospital, it is preferable that contrast agent imaging can be performed with any combination of devices.

  That is, in a medical facility such as a hospital, the use and usage frequency of the radiation irradiation device, the flat detector, and the contrast medium injection device are different for each facility. For this reason, each facility has a plurality of devices with high usage frequency and only one device with low usage frequency, so that the equipment is replenished and expanded while taking into consideration the usage status and budget of the device, etc. There is an advantage that the degree of freedom of equipment installation is improved.

  However, for example, when imaging is performed by injecting a contrast medium into a blood vessel, it may be preferable to link the contrast medium injection device, the radiation irradiation device, and the flat panel detector. In other words, it turned out that there was a problem of how to make those linkages reliable.

  Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a radiation irradiation device and a plane that are separate devices that can be used in combination with other devices for other purposes. In combination with a detector, imaging of contrast agents linked to each other can be realized reliably and inexpensively, and even when radiography in linked mode is not possible, it can be used in control modes other than linked mode, and as a total An object is to provide a contrast medium automatic injection device with high utilization efficiency and a program for operating the same.

  According to the first aspect of the present invention, when the determination means determines that the control means can be controlled in the interlock mode, it communicates with the radiation irradiating apparatus and the flat panel detector, and the contrast agent injection means injects the contrast agent. Since the control means can be controlled in an interlocking mode that interlocks the timing of obtaining a radiation image from the flat panel detector and the timing of radiation irradiation by the radiation irradiation device, the contrast agent imaging in the interlocking mode in which each other is interlocked can be trusted. The contrast agent automatic injection device and the radiation irradiation device or the flat detector are separate devices and can be used in combination with other devices for other purposes. The radiation irradiation device and the flat detector are the contrast agent injection device. In contrast, imaging of contrast medium can be realized at low cost without using an expensive apparatus integrated with the above. In addition, even when radiation imaging in the interlock mode is not possible, it can be used in a control mode other than the interlock mode, and the use efficiency of the contrast agent automatic injection device as a whole increases.

  The invention of claim 2 can select a control mode other than the interlock mode even when the determination means does not determine that the control means can control in the interlock mode. The apparatus can be used by moving or by itself.

  In the invention of claim 3, since the determination means determines whether or not it is possible to control in the interlock mode using the detection result of whether or not it is possible to communicate with the radiation irradiation apparatus, the contrast mode imaging in which the two are interlocked with each other. You can make agent photography more reliable.

  In the invention according to claim 4, since the determination means determines whether or not it is possible to control in the interlock mode using the detection result of whether or not the radiation irradiation apparatus can irradiate the flat detector. This makes it possible to make the contrast medium imaging in the interlocking mode more reliable.

  In the fifth aspect of the invention, since the determination means determines whether or not it is possible to control in the interlock mode using the detection result of whether or not communication with the flat detector is possible, the contrast mode contrast in which each other is interlocked. You can make agent photography more reliable.

  Since the invention of claim 6 can communicate with the flat detector by wireless communication, it is not necessary to attach a cable or the like, there is a degree of freedom in arranging the flat detector, and the handling is simplified, Because the determination means determines whether it is possible to control in the interlocking mode using the detection result of the wireless communication state of the wireless communication, the adverse effect due to the uncertainty of the wireless communication is suppressed, and the contrast agent imaging in the interlocking mode in which each other interlocks Can make you more trustworthy.

  According to the seventh aspect of the present invention, the determination means determines whether or not the contrast medium injection means can be controlled in the interlock mode using the detection result of the state whether or not the contrast medium can be automatically injected. This makes it possible to make the contrast medium imaging in the interlocking mode more reliable.

  In the invention of claim 8, when the interlock mode is selected, the image processing apparatus communication means communicates to the image processing apparatus so that the image processing condition is a condition corresponding to the interlock mode. By performing image processing under image processing conditions set according to the interlocking mode, it is possible to obtain an image with higher diagnosis.

Therefore, it is possible to obtain a radiographic image at a more appropriate timing, thereby obtaining a more appropriate radiographic image.

  For example, a means for transmitting a readout signal at a timing to read out a radiation image after radiation irradiation cannot read out the radiation image at an appropriate timing if communication fails at the timing to read out the radiation image. On the other hand, in the invention of claim 14, since the flat detector communication means transmits information on the timing for reading out the radiographic image to the flat detector before radiography, even if transmission fails, it is transmitted again. Thus, the radiation image can be read out at an appropriate timing, and a more appropriate image can be obtained.

  In the fifteenth aspect of the invention, the operator can identify whether or not the interlock mode can be selected by displaying the operation screen, and can select an appropriate control mode according to the mode.

Can be selected.

  According to the seventeenth aspect of the present invention, only when the control means determines that the control can be performed in the interlocking mode, the timing of injecting the contrast medium by the contrast medium injecting means and the plane detection are communicated with the radiation irradiation apparatus and the flat detector. The control means can control the interlocking mode in which the timing of obtaining the radiation image from the vessel and the timing of irradiation of the radiation by the radiation irradiating apparatus. The automatic injection device, the radiation irradiation device, and the flat detector are separate devices, and can be used in combination with other devices for other purposes. The radiation irradiation device and the flat detector are integrated with the contrast agent injection device. Contrast agent imaging can be realized at low cost without using an expensive apparatus. In addition, even when radiation imaging in the interlock mode is not possible, it can be used in a control mode other than the interlock mode, and the use efficiency of the contrast agent automatic injection device as a whole increases.

  This column is a column for specifying and explaining the embodiment considered to be the best of the present invention, and the description of this column does not specify or limit the meaning of the term of the present invention or the scope of the present invention.

  Hereinafter, an embodiment of an automatic contrast medium injection device according to the present invention will be described with reference to FIGS. 1 to 6.

  In the present embodiment, as shown in FIG. 1, the contrast medium automatic injection device 1 is irradiated with X-rays which are a kind of radiation irradiation device for irradiating a subject M (see FIG. 2) as a patient, for example. An X-ray irradiation apparatus 2 that performs X-ray images generated by X-rays emitted from an X-ray irradiation apparatus 2 that is a kind of flat panel detector that obtains a radiation image of radiation emitted from the radiation irradiation apparatus, and an FPD 3 An image processing apparatus 4 that performs various types of image processing such as gradation processing on the obtained X-ray image can be connected via the network 5. Here, the network 5 may be a dedicated communication line for the system, but is an existing line such as Ethernet (registered trademark) for the reason that the degree of freedom of the system configuration becomes low. Is preferred. In addition, the network 5 may be connected to a server that manages information related to radiographic imaging such as information on the subject M and imaging conditions. Note that the contrast medium automatic injection device 1, the X-ray irradiation device 2, the FPD 3 and the image processing device 4 can be used as separate bodies, and can be connected to the network 5 or disconnected from the network as necessary. You can.

  First, the X-ray irradiation apparatus 2 includes an X-ray tube 23 that emits X-rays that are radiation, and a high-voltage power supply 6 that supplies a high voltage to the X-ray tube 23. X-rays are generated by supplying a high voltage to the subject M and irradiated onto the subject M. Further, the X-ray irradiation apparatus 2 is provided with a diaphragm device (not shown) for narrowing the X-rays irradiated from the X-ray tube 23 to a desired range, and irradiation is performed according to the type of imaging or the imaging target. Narrow the X-rays to be performed.

  The X-ray irradiation device 2 is provided with an irradiation device communication unit 7 for communicating with an external device such as the contrast medium automatic injection device 1. The X-ray irradiation apparatus 2 receives information on irradiation conditions such as an X-ray dose and an X-ray aperture range input from an external device via the irradiation apparatus communication unit 7. According to these externally input irradiation conditions, a predetermined tube voltage is applied to the X-ray tube 23 and a tube current is applied, and the X-ray is narrowed down to a predetermined range by the aperture device, and an X-ray with a dose suitable for imaging is obtained. M is irradiated.

  Further, the X-ray irradiation apparatus 2 is provided with an X-ray irradiation detection sensor 24 which is a detection means for detecting whether or not the FPD 3 can be normally irradiated with X-rays. The result detected by the sensor 24 (see FIG. 2) is sent as a signal from the irradiation device communication unit 7 to the contrast medium automatic injection device 1. It should be noted that the detection of whether or not X-rays can be normally irradiated does not necessarily have to be highly accurate, and may be performed so long as the state of the X-ray irradiation apparatus 2 can be roughly grasped.

  As a state in which the X-ray irradiation apparatus 2 cannot irradiate the FPD 3 with X-rays, for example, the high-voltage power supply 6 or the X-ray tube 23 of the X-ray irradiation apparatus 2 is broken or deteriorated, or the high-voltage power supply 6 Is in a ready state and cannot immediately supply high-voltage power. Even if there is no problem with the high-voltage power supply 6 or the X-ray tube 23 itself, the X-ray irradiation apparatus 2 is not associated with the FPD 3 used for imaging, or the X-ray irradiation of the X-ray irradiation apparatus 2 is performed. When the direction is not directed to the FPD 3, the FPD 3 cannot be irradiated with X-rays.

Thus, examples of the detection means for detecting whether or not the FPD 3 can be normally irradiated with X-rays include, but are not limited to, the following. For example, the X-ray irradiation apparatus 2 may be provided with an X-ray dose sensor that measures the X-ray dose emitted from the X-ray tube 23, and may be a sensor that detects whether or not a predetermined amount of X-rays has been irradiated under a predetermined condition. . Moreover, the sensor which detects that predetermined adjustment was completed by providing the operation part which adjusts the X-ray irradiation direction of the X-ray irradiation apparatus 2, and operating this operation part may be sufficient. The sensor which detects the X-ray irradiation direction of the X-ray irradiation apparatus 2 may be sufficient. Alternatively, a sensor that pre-irradiates predetermined X-rays from the X-ray irradiation apparatus 2 and detects whether or not the FPD 3 can detect the predetermined X-rays may be used.
Further, for example, as shown in FIG. 2, when the contrast medium automatic injection device 1 is provided with a C-type arm 26 that fixedly provides the X-ray irradiation device 2 at a predetermined position and irradiates X-rays in a predetermined direction. As an X-ray irradiation detection sensor 24 which is a detecting means for detecting whether or not the FPD 3 can be normally irradiated with X-rays, a C-shaped arm 26 in the X-ray irradiation field of the X-ray irradiation apparatus 2 is used. A sensor for detecting whether or not the FPD 3 is loaded at a predetermined position may be provided. In this case, the FPD 5 is portable, detachable from the loading slot 25, and can be carried freely. The signal line 17 of the contrast medium automatic injection device 1 is provided along the C-arm, the tip of the signal line 17 is provided in the loading slot 25, and wireless communication with the FPD communication unit 8 of the FPD 5 is possible. This is preferable because the reliability of communication is increased. Further, when the FPD 5 is loaded in the loading slot 25, a wired connection may be used. Note that the C-type arm 26 can be rotated in the YJ direction in FIG. 2 by the arm driving unit 27 by the control unit 20 of the X-ray irradiation apparatus 2, and the subject M on the bed 29 can be X-rayed from any direction. Is.

Next, the FPD 3 is, for example, a cassette-type FPD 3, and detects X-rays emitted from the X-ray irradiation apparatus 2 and transmitted through the subject M within the X-ray irradiation field. It is placed at a position where it can. By using such a cassette type FPD 3, it is possible to easily exchange the FPD 3. The FPD 3 is not limited to the cassette type.
In the case of a cassette type FPD, a portable cableless cassette FPD that can communicate directly or indirectly with the contrast medium automatic injection device 1 via wireless communication and has an internal power supply for supplying power for driving the FPD. Preferably there is. This eliminates the need to carefully handle the cassette so that the cable does not get tangled with the subject during X-ray photography, allowing the operator to concentrate on X-ray photography, reducing mistakes, and extra exposure to the subject. The total shooting efficiency is improved while suppressing the occurrence of exposure.

  Further, the FPD 3 is provided with an FPD communication unit 8 for communicating with an external device such as the contrast medium automatic injection device 1 by radio signals, and image information is transmitted from the external device to the FPD 3 via the FPD communication unit 8. Reading conditions such as the timing of reading and other information are sent. The FPD 3 reads an X-ray image according to the input reading conditions. Note that communication with the FPD communication unit 8 is not limited to wireless communication. Information such as the reading timing of the X-ray image information is sent from the contrast medium automatic injection device 1 to the FPD 3 in advance before imaging, and the FPD 3 reads the X-ray image information based on such information. Do.

  Further, the FPD 3 is provided with an FPD function detection sensor 32 that is a detection means for detecting whether or not the FPD 3 is normally in a state of obtaining an X-ray image, and a result detected by the FPD function detection sensor 32. Is sent from the FPD communication unit 8 to the contrast medium automatic injection device 1 as a signal.

  Further, the image processing device 4 connected to the contrast medium automatic injection device 1 performs various image processing on the image information of the X-ray image acquired by the FPD 3. Image processing performed by the image processing device 4 includes gradation processing for adjusting image contrast, contrast correction processing for detecting abnormal shadow candidates, frequency enhancement processing for adjusting image sharpness, and images with a wide dynamic range. Dynamic range compression processing and the like are included so as to be within an easy-to-see density range without lowering the contrast of details. Note that the image processing performed by the image processing device 4 is not limited to this, and other various gradation processing, correction processing, and the like may be performed.

  The image processing device 4 is provided with a processing device communication unit 9 for communicating with an external device such as the contrast medium automatic injection device 1. X-ray image information input from an external device via the processing device communication unit 9 and image processing conditions for the image information are sent to the image processing device 4 as electrical signals. The image processing is performed in accordance with the image processing conditions input from.

  Next, as shown in FIG. 3, the automatic contrast medium injection device 1 in the present embodiment includes a holding unit 35 that holds a syringe 36 that stores a contrast medium as a contrast medium injection unit, and a plunger 37 of the syringe 36. An injection driving unit 10 is provided that is held by the tip chuck 38 and feeds the contrast medium in the syringe 36 into the body of the subject M through the catheter 39. The catheter 39 connected to the syringe 36 is inserted into the body of the subject M.

  Further, the contrast medium automatic injection device 1 is provided with a detection mechanism 11 as an injection availability state detection means for detecting whether or not the contrast medium injection means can normally inject the contrast medium. It should be noted that the detection as to whether or not the contrast medium can be automatically injected does not necessarily have to be highly accurate, and may be performed so long as the state of the contrast medium injection means or the like can be roughly grasped.

  As a state in which the contrast medium injecting unit cannot normally inject the contrast medium, for example, when the injection driving unit 10 is out of order or when the syringe 36 is not loaded at a predetermined position, the injection operation is performed in the syringe 36. For example, there may be a case where there is no remaining contrast agent. Also, the contrast medium injection tip such as the catheter 39 or the contrast medium injection needle is not normally inserted into the body of the subject M, such as being out of the contrast medium flow path, or there is no contrast medium in the middle of the contrast medium flow path. Even when a leak occurs or the contrast medium flow path is clogged, the contrast medium cannot be injected normally.

  Therefore, as the detection mechanism 11 of the contrast medium automatic injection device 1, for example, a detection sensor that detects whether or not the syringe 36 is normally loaded, a sensor that detects the remaining amount of the contrast medium in the syringe 36, The detection sensor that detects whether or not the injection is performed at a predetermined pressure by a pressure sensor that measures the pressure provided in the middle of the catheter 39, and the driving force of the injection drive unit 10 when the contrast medium is injected is within a predetermined range. Examples include a detection sensor that detects whether or not there is. When detecting the driving force of the injection driving unit 10 when injecting the contrast agent, for example, when the contrast agent injection tip is not normally inserted into the body of the subject M or the contrast agent flow path is clogged. In such a case, the driving force exceeds the predetermined range, and in the case where the contrast medium leaks in the middle of the contrast agent flow path, the driving force falls below the predetermined range. It is possible to determine whether or not the contrast medium injection means is in a state where the contrast medium can be injected normally. In addition, a detection sensor that detects whether or not an operation input indicating that the contrast medium injecting unit has confirmed that the contrast medium can be automatically injected has been made to the operation input section is provided.

  Further, the contrast medium automatic injection device 1 communicates with the irradiation device communication unit 7 on the X-ray irradiation device 2 side when connected to the X-ray irradiation device 2, the FPD 3 and the image processing device 4 via the network 5. Is a radiation detector communication means that performs communication with the FPD communication unit 8 on the FPD 3 side, and communicates with the processing device communication unit 9 on the image processing apparatus 4 side. A communication unit 12 serving as an image processing apparatus communication unit is provided. The X-ray irradiation device 2, the flat panel detector 3, and the image processing device 4 can transmit and receive various types of information to and from the contrast medium automatic injection device 1 via the communication unit 12.

  Further, the contrast agent automatic injection device 1 is operated as an operation input means for inputting a part to be imaged and an imaging mode, information on the subject M, conditions on imaging, instructions on reading image information and transmitting / receiving image information, and the like. A portion 13 is provided. For example, as illustrated in FIG. 4, the operation input unit 13 includes an operation panel 131 serving as an operation screen display unit, and various information can be input by the user operating the operation panel 131. In particular, in the present embodiment, as shown in FIG. 4, selection for selecting whether to shoot a moving image or a still image, a region to be photographed, a photographing type, and photographing using a contrast agent, or the like. A screen is displayed, and the user can easily set imaging conditions and the like by selecting a desired imaging region and the like from those displayed on the selection screen.

  The operation input unit 13 is not limited to the one configured with the operation panel 131, and may have other configurations as long as various processing contents can be set. For example, the operation input unit 13 may be configured by a mouse, a keyboard, or the like, and various information may be input by operating the mouse or pressing a key on the keyboard. Further, the instructions and information that can be input from the operation input unit 13 are not limited to those exemplified here.

  The contrast agent automatic injection device 1 is provided with a display unit 14. The display unit 14 includes, for example, a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), and the like, and displays information input from the operation input unit 13 and image information sent from the FPD 3. .

    Furthermore, the contrast medium automatic injection device 1 includes a control unit 15 as a control unit that controls each unit. The control unit 15 includes, for example, a CPU (Central Processing Unit) (not shown) and the like, and executes various processes according to a predetermined program stored in a storage unit (not shown). In particular, in this embodiment, using the FPD communication unit 8 and the irradiation device communication unit 7, the timing for injecting the contrast agent by the contrast agent automatic injection device 1, the timing for obtaining the X-ray image from the FPD 3, and the X-ray irradiation device Only when it is determined whether or not it is possible to control in the interlocking mode that interlocks with the timing of irradiating X-rays, and it is determined that control in the interlocking mode is possible, a plurality of including the interlocking mode The control mode can be selected according to the input from the operation input unit 13 from the control mode, otherwise the control mode is selected according to the input from the operation input unit 13 from the control mode that does not include the interlock mode, and is selected A program for executing processing for controlling the injection of contrast medium by the contrast medium automatic injection device 1 is stored in the storage unit in the control mode. Reading a program developed in a given work area, and controls the respective units to perform the necessary processing in accordance with this program.

  Information input from the operation input unit 13, a signal received by the communication unit 12, and a detection result detected by the detection mechanism 11 are sent to the control unit 15. Whether or not imaging in the interlock mode in which imaging is performed by interlocking the contrast medium injecting means, the X-ray irradiation apparatus 2 and the FPD 3 with each other based on a signal sent from the unit 12 or the detection mechanism 11 It functions as a determination means for determining whether or not.

That is, for example, the control unit 15 causes the communication unit 12 to transmit a predetermined signal to the X-ray irradiation device 2 and the FPD 3, and from the X-ray irradiation device 2 and the FPD 3 to the signal transmitted from the communication unit 12. For example, it is determined whether or not each device is properly connected and can communicate normally depending on whether a predetermined signal such as a readable signal or an irradiable signal is returned.
In addition, when the FPD 3 communicates with the control unit 15 via wireless communication, the contrast medium automatic injection device 1 includes a wireless communication state detection unit (not shown) that detects the state of wireless communication, and the control unit 15 acquires the detection result of the wireless communication state detection means. Then, the control unit 15 determines whether or not it is possible to perform shooting in the interlock mode based on the acquired detection result.
In particular, wireless communication is highly convenient, but has a problem that wireless communication may become impossible or defective. Although there are various types of wireless communication, as means for communicating high-capacity data such as X-ray image data at high speed, for example, optical communication (that is, terawave, infrared wave, visible light, or ultraviolet light) ) And high frequency radio waves such as microwaves.
However, in optical communication, if there is an obstacle on the communication path, communication becomes impossible, and high-frequency radio waves such as microwaves have strong straightness and directivity, and if there are obstacles on the communication path, Problems such as `` Shadowing '' where the signal is blocked by an obstacle and difficult to reach behind the obstacle, and `` Multi Pass Fading '' where the signal is weakened by combining various reflections There is. In particular, in X-ray imaging using an FPD, since the FPD and subject arrangement are finely adjusted for imaging, the subject becomes an obstacle due to the relationship between the FPD and the subject arrangement, and communication failure occurs. Depending on the arrangement of other objects such as a table, another object such as a photographing table may become an obstacle or reflector, resulting in communication failure, or communication failure due to the directivity of the FPD communication unit. In particular, if a metal X-ray shielding member that prevents the influence of X-ray scattering on a photographed image is provided inside the FPD, or if a conductive member such as aluminum is provided as a housing, radio wave absorption or Reflection may occur. In addition, when a wireless communication antenna is provided in the cassette, the metal X-ray shielding member or the conductive housing and the wireless communication antenna are used so that the antenna does not hit the subject or the antenna is broken by the subject. If they are arranged close to each other, strong directivity occurs in the wireless communication on the cassette side. Then, coupled with the subject becoming an obstacle, communication failure and communication failure are likely to occur. Therefore, it is important to detect the state of wireless communication.

  Furthermore, the control unit 15 acquires the results detected by the detection mechanism 11 of the contrast medium injection means and the X-ray irradiation detection sensor 24 of the X-ray irradiation apparatus 2, and based on the detection result, the control medium injection means and the X It is determined whether or not the beam irradiation device 2 can operate normally. Then, based on these determination results, the control unit 15 is in a state where it is possible to perform imaging in an interlocking mode in which the contrast medium injecting means, the X-ray irradiation apparatus 2 and the FPD 3 operate in conjunction with each other. Determine whether.

  In addition, it is possible to determine whether all of the contrast medium injection means, the X-ray irradiation apparatus 2, and the FPD 3 are capable of normal communication operation, and to control in the interlocking mode because each apparatus is operating normally. The determination as to whether or not the device is in a proper state does not necessarily have to be highly accurate, as long as it is possible to roughly grasp the state of whether or not each device can be linked. Moreover, in this embodiment, it is judged whether the contrast agent automatic injection device 1 is in a state where it can communicate with the X-ray irradiation device 2 and the FPD 3, and the contrast agent injection means, the X-ray irradiation device 2, and the FPD 3 The control unit 15 of the contrast medium automatic injection device 1 determines whether or not both are in a normal operating state, but a method for determining whether communication is possible between the devices is shown here. The determination is not limited to this, and these determinations may be performed on the X-ray irradiation apparatus 2 or FPD 3 side, and the determination results may be sent to the control unit 15 of the contrast medium automatic injection apparatus 1. Moreover, in this embodiment, the communication part 12 of the contrast agent automatic injection apparatus 1 can communicate with both the X-ray irradiation apparatus 2 and the FPD 3, and the X-ray irradiation apparatus 2 can irradiate X-rays. Control in the interlock mode only when the FPD 3 can normally detect X-rays and the contrast agent injection means is in a state where the contrast agent can be injected. However, for example, it is possible to exclude those that have a very low probability of being impossible from the judgment conditions, or substitute one of them for other judgment conditions. .

  Further, when the control unit 15 determines that it is possible to take an image in the interlock mode, a screen on which the interlock mode as shown in FIG. 4 can be selected on the selection screen of the operation panel 131 of the operation input unit 13 Is displayed. On the other hand, when determining that it is impossible to capture an image in the interlock mode, the control unit 15 displays, for example, a cardiovascular angiography or blood vessel shown in FIG. 4 on the selection screen of the operation panel 131 of the operation input unit 13. Only modes other than those in which imaging is performed in a linked mode such as contrast are displayed. In this way, by displaying the screen that can select the interlocking mode only when the interlocking mode can be set, the interlocking mode is not erroneously set when the interlocking mode cannot be selected. Further, the control unit 15 may cause the display unit 14 to display the selected type of imaging, imaging region, subject information, and the like.

  Furthermore, when it is set to perform imaging in the interlocking mode, the control unit 15 controls the X-ray irradiation apparatus 2 via the communication unit so that X-rays are irradiated under irradiation conditions according to the interlocking mode. . Here, the irradiation conditions for controlling the X-ray irradiation apparatus 2 refer to conditions for controlling the quality or quantity of X-rays irradiated from the X-ray irradiation apparatus 2. The control unit 15 stores, for example, a plurality of irradiation conditions corresponding to the interlocking mode and a control pattern corresponding thereto in advance in the storage unit, and the control unit 15 controls the X-ray irradiation apparatus 2 according to the control pattern. I do.

Examples of the control under the irradiation condition according to the interlocking mode include performing control using a predetermined data value corresponding to the elapsed time from the injection time of the contrast agent or the elapsed time. For example, since it takes some time from the start of injection of the contrast agent to reach the imaging target site, this time is set in advance, and the injection of the contrast medium into the body starts before reaching the imaging target site. The irradiation timing for irradiating X-rays is determined so that X-ray irradiation is performed after a predetermined time until the operation.
Immediately after the start of the injection of the contrast agent, the contrast agent is unevenly distributed in the blood vessel and strongly absorbs X-rays only in the blood vessel. For this reason, in order to perform imaging so that the blood vessel image becomes clear immediately after injection of the contrast agent, control for increasing the X-ray dose is performed. That is, for example, in the case of the X-ray tube 23, the tube voltage or tube current supplied from the high voltage power source 6 is increased or the irradiation time is increased. As the time elapses, the contrast medium infiltrates into the tissue and X-rays are weakly absorbed. Therefore, the tissue image becomes clear after a predetermined time has elapsed from the start of the injection of the contrast medium. In order to perform such imaging, control for reducing the X-ray dose is performed. On the other hand, when an imaging mode other than the interlocking mode is set, control is performed under these intermediate irradiation conditions regardless of the elapsed time from the injection of the contrast agent.

  In addition, when moving image shooting is performed in the interlock mode, the control unit 15 performs control so that X-ray irradiation is performed under an irradiation condition in which a change in display density is small in accordance with an elapsed time from the time of contrast agent injection. To do. For example, the contrast medium concentration in the blood vessel is very high for a while after the start of the injection of the contrast medium, but the contrast medium concentration decreases with time. For this reason, regardless of the elapsed time, if X-rays are irradiated under the same irradiation conditions, the X-ray exposure is insufficient immediately after the start of the injection of the contrast agent, and conversely, the X-ray exposure tends to be excessive after a predetermined time has elapsed. Therefore, when the interlocking mode is selected, the X-ray dose to be irradiated is controlled in accordance with the elapsed time from the injection of the contrast agent, so that the fluctuation of the blood vessel image is reduced. On the other hand, when an imaging mode other than the interlocking mode is set, control is performed under these intermediate irradiation conditions regardless of the elapsed time from the injection of the contrast agent.

  When the interlock mode is set, the control unit 15 controls the X-ray irradiation apparatus 2 to irradiate X-rays according to irradiation conditions according to the contrast agent injection amount, injection speed, injection pattern, and the like. You may do it. For example, X-rays are absorbed more strongly as the injection amount of the contrast agent is larger and the injection speed is faster. Therefore, the X-ray irradiation amount is increased, the smaller the injection amount of the contrast agent and the slower the injection rate, The irradiation conditions are set so as to reduce the irradiation amount, and the control unit 15 performs control according to this.

  Further, when it is set to perform shooting in the interlocking mode, the control unit 15 controls the image processing apparatus 4 to perform image processing under image processing conditions corresponding to the interlocking mode. That is, for example, the control unit 15 stores in advance a plurality of image processing conditions corresponding to the interlock mode and a control pattern corresponding to the image processing apparatus 4 according to the control pattern. Control.

  Examples of the control under the image processing condition according to the interlocking mode include, for example, when the interlocking mode is set, performing control using the elapsed time from the injection of the contrast agent or a data value corresponding to the elapsed time. . For example, immediately after the start of the injection of the contrast agent, the contrast agent is unevenly distributed in the blood vessel, and X-rays are strongly absorbed only in the blood vessel. Therefore, immediately after the start of the injection of the contrast agent, control is performed so as to perform image processing so as to give a contrast in a low density region in order to clarify a blood vessel image. As the time passes, the contrast medium penetrates into the tissue and X-rays are weakly absorbed. After a predetermined time has passed, the contrast of the medium density region should be set to clarify the tissue image. Control to perform image processing. On the other hand, when an imaging mode other than the interlock mode is set, intermediate image processing is performed regardless of the passage of time from the start of contrast medium injection.

  In addition, when moving image shooting is performed in the interlocking mode, control is performed so that image processing is performed so that a change in display density becomes small according to the elapsed time. For example, the contrast agent concentration in the blood vessel is very high immediately after the start of the injection of the contrast agent, but the contrast agent concentration decreases with time. For this reason, since it is difficult to recognize the image when displayed without any adjustment, the control unit 15 controls the image processing apparatus 4 to adjust the contrast of the image according to the elapsed time from the start of the injection of the contrast agent. I do. On the other hand, when an imaging mode other than the interlocking mode is set, intermediate image processing is performed regardless of the elapsed time from the start of contrast agent injection.

  When the interlocking mode is set, the control unit 15 controls the image processing apparatus 4 to perform image processing according to image processing conditions according to the contrast agent injection amount, injection speed, injection pattern, and the like. It may be. For example, the higher the injection amount of the contrast agent, the higher the injection speed, the stronger the X-ray absorption, so the concentration is increased, and the lower the injection amount of contrast agent, the lower the injection rate, the lower the concentration. The image processing conditions are set in the control unit 15, and the control unit 15 performs control according to the image processing conditions.

  The control unit 15, the operation input unit 13, the display unit 14, the communication unit 12, the injection drive unit 10, the detection mechanism 11, and the like are connected by a bus 16.

Next, the operation of the contrast medium automatic injection device 1 according to this embodiment will be described with reference to FIGS. 5 and 6.
In the present embodiment, the control unit 15 reads out the program related to the contrast medium injection from the storage unit, develops it in a predetermined work area, and executes the following series of processes by controlling each part of the apparatus according to the program. It is like that.

  First, when an X-ray image is taken, a predetermined signal is transmitted from the communication unit 12 of the contrast agent automatic injection device 1 to the X-ray irradiation device 2, and the contrast agent automatic injection device 1 and the X-ray irradiation are transmitted. It is determined whether or not the device 2 can communicate with each other (step S1). When a predetermined signal is returned from the X-ray irradiation device 2 to the signal transmitted from the communication unit 12, the control unit 15 is in a state in which the contrast medium automatic injection device 1 and the X-ray irradiation device 2 can communicate with each other. Judge that there is. When there is no reply from the X-ray irradiation device 2, it is determined that communication is impossible, and it is determined that it is impossible to operate in the interlock mode (step S2). Further, when the control unit 15 determines that the contrast agent automatic injection device 1 and the X-ray irradiation device 2 are in a state where they can communicate with each other, the communication unit 12 of the contrast agent automatic injection device 1 sends an FPD 3 to the FPD 3. A predetermined signal is transmitted, and it is determined whether or not the communication unit 12 of the contrast medium automatic injection device 1 and the FPD 3 are in a state where they can communicate with each other (step S3). When a predetermined signal is returned from the FPD 3 in response to the signal transmitted from the communication unit 12, the control unit 15 determines that the communication unit 12 and the FPD 3 are in a state where they can communicate with each other. When there is no reply from the FPD 3, it is determined that communication is not possible, and it is determined that it is impossible to operate in the interlock mode (step S2).

  When it is determined that both the FPD 3 and the X-ray irradiation apparatus 2 can communicate with the communication unit 12, the detection mechanism 11 detects whether or not the contrast medium injection unit can normally automatically inject the contrast medium. Then, the detection result is sent to the control unit 15. The control unit 15 determines whether or not the contrast medium injecting means can normally inject the contrast medium from the acquired detection result (step S4). Is determined to be impossible (step S2). On the other hand, when the control unit 15 determines that automatic injection is possible, the control unit 15 causes the X-ray irradiation apparatus 2 to normally emit X-rays toward the FPD 3 from the detection means installed in the X-ray irradiation apparatus 2. A detection result obtained by detecting whether or not irradiation is possible is acquired via the communication unit 12. The control unit 15 determines whether or not the X-ray irradiation apparatus 2 can normally irradiate X-rays from the acquired detection result (step S5). It is determined that this is impossible (step S2). On the other hand, when the control unit 15 determines that X-ray irradiation is possible, the control unit 15 further causes the FPD 3 to normally emit X-rays in conjunction with the contrast medium automatic injection device 1 and the X-ray irradiation device 2. It is determined whether or not the reading operation can be performed (step S6). If it is determined that the reading operation is impossible, it is determined that the operation in the interlock mode is impossible (step S2). On the other hand, if the control unit 15 determines that it is possible to perform a linked reading operation, it is determined that the FPD 3, the contrast medium automatic injection device 1, and the X-ray irradiation device 2 can be linked ( Step S7), the control in the interlock mode is performed for each part.

  That is, as shown in FIG. 6, the control unit 15 determines whether it is possible to select an interlocking mode in which the contrast medium automatic injection device 1, the X-ray irradiation device 2, and the FPD 3 are interlocked as the imaging mode. (Step S8). When the control unit 15 determines that the interlock mode can be selected, a selection screen including the interlock mode is displayed on the operation panel 131 of the operation input unit 13 (step S9). When the shooting mode is selected by the user and input from the operation input unit 13 (step S10), the control unit 15 further determines whether or not the shooting mode selected by the user is the interlocking mode (step S11). . When the selected imaging mode is the interlocking mode, the X-ray dose irradiated from the X-ray irradiation device 2 in accordance with the elapsed time from the time when the contrast agent injection is started from the contrast agent automatic injection device 1 For example, the X-ray irradiation apparatus 2 and the image processing apparatus 4 are controlled so as to adjust the image processing and the image processing in the image processing apparatus 4. (Step S12). On the other hand, when the selected imaging mode is an imaging mode other than the interlocking mode, constant control is performed on each unit regardless of the elapsed time from the time when the injection of the contrast medium is started (step S13). ).

  On the other hand, when the control unit 15 determines that the interlock mode cannot be selected, a selection screen not including the interlock mode is displayed on the operation panel 131 of the operation input unit 13 (step S14). When the imaging mode is selected by the user and input from the operation input unit 13 (step S15), each unit is set according to the input imaging mode regardless of the elapsed time from the time when the injection of the contrast medium is started. A certain control is performed for.

  As described above, according to the present embodiment, the contrast medium automatic injection device 1, the FPD 3, and the X-ray irradiation device 2 that can be used alone are connected through the network 5 as necessary, and the devices communicate with each other. It is determined whether or not an operation suitable for interlocking can be performed, and control in the interlocking mode can be performed only when it is determined that interlocking is possible. For this reason, since each device can be linked with high accuracy, even when each single device is used in combination, the contrast agent can be safely applied without overloading the subject as in the case of an integrated device. The X-ray image used can be taken.

  In the present embodiment, the screen for selecting the interlock mode is displayed on the selection screen of the operation input unit 13 only when the control unit 15 determines that the interlock mode can be selected. The display screen displays a screen on which all modes including the interlock mode can be selected regardless of whether or not the interlock mode can be selected. When the interlock mode cannot be selected, the operation input unit 13 tries to select the interlock mode. When this is done, a message indicating that the interlock mode cannot be selected is displayed.

Further, the flow of processing for determining whether or not the interlocking mode can be selected is not limited to that shown in FIG. 3, and the determination may be made in a different order.
Moreover, it is preferable that the control part 15 displays the determination result in each step on the operation panel 131. As a result, the operator can grasp the cause of determining that the interlock is impossible, and can take a countermeasure corresponding to the cause.
