Description

  The present invention relates to a radiographic image capturing apparatus, a radiographic image capturing system, a radiographic image capturing program, and a radiographic image capturing method for capturing a radiographic image indicated by irradiated radiation.

  Conventionally, a radiographic imaging system that performs radiography for the purpose of medical diagnosis is known. The radiographic imaging system includes a radiation generating apparatus that generates radiation, a radiographic imaging apparatus that detects radiation transmitted through the subject and captures a radiographic image, a radiation detector such as a cassette, and the radiation generation There is a radiographic imaging system including a device and a control device that controls the radiation detector.

  In a radiation detector, there is a technique for performing settings related to radiographic image capture without receiving an instruction from an external device such as a control device.

  For example, Patent Document 1 describes a technique for detecting whether the casing of an electronic cassette has been touched by a user and changing the state of power supply from a battery. Further, for example, Patent Document 2 describes a technique for extracting an irradiation region and a region of interest for gradation conversion in accordance with a recognition result of a two-dimensional contact sensor provided on the imaging surface of a cassette.

  By the way, it is preferable to set the radiation detector itself without receiving an instruction from an external device such as a control device. There are settings related to wireless communication for communicating image data and the like.

  In recent years, a wireless radiation detector connected to a control device by wireless communication such as a wireless LAN (Local Area Network) is known. In such a wireless radiation detector, various setting instructions are given from a control device connected by wireless communication. However, as an exception, an ID (for example, wireless) for determining the association between the control device and the radiation detector. In the case of a LAN, settings may not be made for a so-called ESSID (Extended Service Set Identifier), which is a network identifier (ID) in a wireless LAN, and the same IDs are linked and connected. If the setting is changed, the control device associated with the radiation detector may be switched, so that the setting may not be performed.If the switched control device does not exist, the radiation detector will be referred to hereinafter. The linked control device does not exist, and no linking action can be performed. There is a case where the setting cannot be changed, and as a result, there is a problem that the radiation detector becomes unusable.For example, a certain radiation detector is connected to the control device A in the room A in the room A ( Such a failure may occur when the radiation detector is brought into the room B and used to connect to the control device B in the room B after use.

  In order to suppress the occurrence of such a failure, it is possible to change settings related to wireless communication via a wired network. Further, for example, the technique described in Patent Document 1 can be used. Patent Document 1 discloses an access point (terminal device) connected to a radiographic image detection device in order to easily associate radiographic image data acquired by radiography with a console (control terminal) even when moving between radiographing rooms. ) Is described. Further, there is described a technique for connecting to an access point having the highest radio wave intensity when there are a plurality of access points connected to one radiation image detection apparatus.

  However, when a setting related to wireless communication is changed via a wired network, a workflow for switching from wireless communication to wired communication occurs, which reduces user convenience. Moreover, it is necessary to provide a function for performing wired communication, and the cost may increase due to wired connection.

  On the other hand, the technique described in Patent Document 1 has the following problems, and the control device and the radiation detector cannot be properly linked, and the above-described failure may occur. .

  For example, the access point connected to the radiation image detection device or the access point with the strongest radio wave intensity is not necessarily in the room where the radiation image detection device is brought in, and is linked to an access point different from the access point to be connected. You might get lost. For example, it may be connected to an access point in a room in an adjacent room or an access point in a far room has a higher radio wave intensity. Further, for example, there may be a case where no access point is connected.

  In view of such a problem of the conventional technique, the present invention appropriately sets setting information related to radiographic image capturing according to the user's intention in a radiographic image capturing apparatus that captures a radiographic image as compared with the conventional technique. It is an object of the present invention to provide a radiographic image capturing apparatus, a radiographic image capturing system, a radiographic image capturing program, and a radiographic image capturing method that can be set as follows.

  In order to achieve the above object, the radiographic image capturing apparatus according to claim 1 provides a correspondence relationship between a motion pattern of an indicator and setting information of a function related to radiographic image capturing indicated by the motion pattern.

And a setting means for setting a.

  The storage unit stores in advance a correspondence relationship between the movement pattern of the pointing object and the setting information for setting the setting information of the function related to the radiographic image shooting indicated by the movement pattern. The detecting means detects a change in light caused by the movement of the indicator or a change in contact state caused by the movement of the indicator.

Further, by detecting a change in infrared light, setting information can be set without the user touching the radiation image capturing apparatus.

  In the radiographic imaging apparatus according to the third aspect of the present invention, the function related to radiographic image capturing may be a function for performing wireless communication related to radiographic image capturing with an external apparatus.

  It may be preferable to perform settings related to wireless communication in a state in which the setting is not connected to an external device, such as setting an identifier (ID). Since the present invention can be set in a state in which it is not connected to an external device or the like, a higher effect can be obtained when applied to such a case.

  Further, according to the present invention, a movement pattern based on a change in light detected by the detection unit or a movement pattern based on a change in contact state is predetermined as in the radiographic image capturing apparatus according to claim 4. In the case of a movement pattern, control means may be provided for controlling the judgment means to make a judgment.

  Hereinafter, an example of the radiographic imaging system of the present exemplary embodiment will be described with reference to the drawings. In FIG. 1, an example of schematic structure of the radiographic imaging system which concerns on this Embodiment is shown. FIG. 1 shows a case where a similar radiographic imaging system 10 (10A, 10B, 10C) is installed for each of the rooms A, B, and C. Hereinafter, in order to distinguish the radiographic imaging systems 10A, 10B, 10C, etc. provided for the rooms A, B, C and the rooms A, B, C, the explanation will be given with reference numerals A, B, C. When referring generically without distinction, the description of the symbols A, B and C is omitted.

  The radiographic imaging system 10 of the present exemplary embodiment includes a control device 12, a radiation generation device 14, and a radiation detector 16.

  The control device 12 is wirelessly connected to the radiation detector 16 and has a function of executing various controls on the radiation detector 16 by wireless command / data transmission via the communication I / F 26. The control device 12 is connected to the radiation generation device 14 and has a function of controlling the timing of generating radiation (for example, X-ray (X-ray) or the like). The control device 12 includes a CPU (Central Processing Unit) 20, a memory 22, a processing unit 24, and a communication I / F 26. The CPU 20, the memory 22, the processing unit 24, and the communication I / F 26 are configured with a CPU. Signals are mutually connected by a bus 28 such as a bus. The CPU 20 has a function of controlling the overall operation of the control device 12 by executing various programs stored in the memory 22 in advance. The processing unit 24 has a function of acquiring image data from the radiation detector 16 and performing various processes.

  The radiation generation device 14 irradiates the subject 18 with radiation from the radiation tube 15 at a timing based on the control of the control device 12. The radiation irradiated from the radiation generation device 14 passes through the subject 18 so as to carry image information and is irradiated to the radiation detector 16.

  In FIG. 2, the functional block diagram of an example of the schematic structure of the radiation detector 16 of this Embodiment is shown. The radiation detector 16 of the present embodiment is an FPD (Flat Panel Detector), such as a so-called cassette.

  The radiation detector 16 includes a TFT (Thin Film Transistor) unit 30, a charge amplifier / MUX (multiplexer) 32, an A / D converter 34, a control unit 36, a gate drive unit 38, a wireless communication unit 40, a storage unit 42, A detection unit 44, a detection unit 45, a display unit 46, and a power supply unit 48 are provided. The TFT unit 30, the charge amplifier / MUX 32, the control unit 36, the gate drive unit 38, the wireless communication unit 40, the storage unit 42, and the power supply unit 48 are housed in a housing 49 (see FIG. 5), and a detection unit 44, the detection unit 45, and the display unit 46 are provided in the housing 49.

  The TFT unit 30 has a function of detecting the irradiated radiation. FIG. 3 is a cross-sectional view schematically showing an example of the configuration of the TFT unit 30. As shown in FIG. 3, the radiation detector 16 includes a TFT substrate 54 in which a switch element 52 such as a TFT is formed on an insulating substrate 50.

The switch element 52 is connected to a gate line 68 for turning each switch element 52 on and off. A scintillator layer 56 that converts incident radiation into light is formed on the TFT substrate 54. As the scintillator layer 56, for example, CSI: Tl, Gos (Gd ₂ O ₂ S: Tb) phosphor or the like can be used. The scintillator layer 56 is not limited to these materials.

  As the insulating substrate 50, for example, a glass substrate, various ceramic substrates, a resin substrate, or the like can be used, but is not limited to these materials.

  Between the scintillator layer 56 and the TFT substrate 54, a photoconductive layer 58 that generates charges when light converted by the scintillator layer 56 is incident is disposed. A bias electrode 60 for applying a bias voltage to the photoconductive layer 58 is provided on the surface of the photoconductive layer 58 on the scintillator layer 56 side.

  The TFT substrate 54 is provided with a charge collection electrode 62 for collecting charges generated in the photoconductive layer 58. On the TFT substrate 54, the charges collected by the charge collection electrodes 62 are read out by the switch element 52.

  The charge collection electrodes 62 are arranged in a matrix (two-dimensional shape) on the TFT substrate 54, and the switch element TFTs are arranged in a matrix on the insulating substrate 50 correspondingly. A flattening layer 64 for flattening the TFT substrate 54 is formed on the TFT substrate 54. An adhesive layer 66 for bonding the scintillator layer 56 to the TFT substrate 54 is formed between the TFT substrate 54 and the scintillator layer 56 and on the planarizing layer 64.

  The radiation detector 16 may be irradiated with radiation from the front side to which the scintillator layer 56 is bonded, or may be irradiated with radiation from the TFT substrate 54 side (back side). The radiation detector 16 emits light more strongly on the upper surface side (opposite side of the TFT substrate 54) of the scintillator layer 56 when irradiated with radiation from the front side, and transmitted through the TFT substrate 54 when irradiated with radiation from the back side. Radiation enters the scintillator layer 56, and the TFT substrate 54 side of the scintillator layer 56 emits light more intensely. Electric charges are generated in each photoconductive layer 58 by the light generated in the scintillator layer 56. For this reason, the radiation detector 16 can be designed with higher sensitivity to radiation because radiation does not pass through the TFT substrate 54 when radiation is irradiated from the front side than when radiation is irradiated from the back side. Moreover, since the light emission position of the scintillator layer 56 with respect to each photoconductive layer 58 is closer when the radiation is irradiated from the back side than when the radiation is irradiated from the front side, the radiation image obtained by imaging High resolution.

  The structure of the TFT unit 30 is not limited to this, and is not limited as long as it has a function of accumulating and outputting charges according to the radiation applied to the radiation detector 16. May be. An example of another structure of the TFT section 30 is shown in FIG. FIG. 4 is a cross-sectional view schematically showing another example of the configuration of the TFT section 30. The TFT unit 30 shown in FIG. 4 shows a direct conversion type structure in which radiation is directly converted into electric charges by a sensor unit using amorphous selenium or the like.

In the TFT section 30 shown in FIG. 4, a photoconductive layer 59 that converts incident radiation into electric charges is formed on the TFT substrate 54 as an example of a radiation conversion layer that converts incident radiation. As the photoconductive layer 59, amorphous selenium (a-Se), Bi ₁₂ MO ₂₀ (M: Ti, Si, Ge), Bi ₄ M ₃ O ₁₂ (M: Ti, Si, Ge), Bi ₂ O ₃ , BiMO ₄ (M: Nb, Ta, V), Bi ₂ WO ₆ , Bi ₂₄ B ₂ O ₃₉ , ZnO, ZnS, ZnSe, ZnTe, MNbO ₃ (M: Li, Na, K), PbO, HgI ₂ , PbI ₂ , compounds such as CdS, CdSe, CdTe, BiI ₃ , GaAs, etc. are used, but they have high dark resistance, show good photoconductivity against radiation, and are vacuum-deposited. An amorphous material capable of forming a large area film at a low temperature by the method is preferable.

  On the photoconductive layer 59, a bias electrode 61 that is formed on the surface side of the photoconductive layer 59 and for applying a bias voltage to the photoconductive layer 59 is formed.

  In the direct conversion type TFT unit 30, as in the indirect conversion type TFT unit 30 (see FIG. 3 described above), a charge collection electrode 62 that collects charges generated in the photoconductive layer 59 is formed on the TFT substrate 54. ing.

  In addition, the TFT substrate 54 in the direct conversion type TFT unit 30 includes a charge storage capacitor 63 that stores charges collected by the charge collection electrodes 62. The charge accumulated in each charge storage capacitor 63 is read by the switch element 52.

  The electric charges read out in the TFT section 30 are output to the charge amplifier / MUX 32 as an electric signal. The charge amplifier 32 has a function of amplifying an electrical signal and converting it into an analog voltage as electrical information. As a specific example, the charge amplifier 32 includes an amplifier circuit and a sample hold circuit using an operational amplifier and a capacitor. Yes. The electric signal held in the sample-and-hold circuit is configured to perform parallel-serial conversion by the MUX 32 and output to the A / D converter 34.

  The A / D converter 34 has a function of converting a serially input analog voltage into a digital signal that is easier to handle. The two-dimensional image data of the radiation image converted into a digital signal by the A / D converter 34 is output to the control unit 36. In the present embodiment, the A / D converter 34 is connected to an image memory (not shown), and the transmitted image data is stored in the image memory in order. In this embodiment, the image memory has a storage capacity capable of storing a predetermined number of image data, and each time a radiographic image is captured, the image data obtained by the imaging is sequentially stored in the image memory. It is configured to be.

  The control unit 36 is configured by a microcomputer, and includes a CPU 36A, a memory 36B including a ROM and a RAM, a non-volatile storage unit 36C including a flash memory, and the like. Various programs stored in the memory 36B are stored in the CPU 36A. It has a function which controls operation | movement of the radiation detector 16 whole by performing by. In the present embodiment, the control unit 36 determines whether a movement pattern that matches the user's gesture detected by the detection unit 44 and the detection unit 45 is stored in the storage unit 42. The wireless communication unit 40 has a function of setting the wireless communication unit 40 based on the wireless communication setting associated with the stored motion pattern (details will be described later).

  The image data is further transmitted to the wireless communication unit 40. The wireless communication unit 40 has a function of wirelessly transmitting image data for each line. As described above, the wireless communication unit 40 according to the present embodiment has a function of performing wireless communication with an external device (in this case, the control device 12). IEEE (Institut of Electrical and Electronics Engineers) 802.11a / b / It corresponds to the wireless LAN standard represented by g and the like, and controls transmission of various types of information to and from external devices by wireless communication. The wireless communication unit 40 performs wireless communication with the associated network with reference to the set ESSID.

  Further, through the wireless communication unit 40, the control unit 36 can wirelessly communicate with an external device that controls the entire radiographic imaging such as the control device 12, and various information can be communicated with the control device 12. Transmission and reception are possible. When capturing a radiographic image of the subject 18, the control unit 36 stores various information such as imaging conditions and subject 18 information received from the control device 12 via the wireless communication unit 40, and is based on the imaging conditions. The charge is read out.

  As shown in FIG. 5, the detection unit 44 and the detection unit 45 are provided in a housing 49 of the radiation detector 16. FIG. 5 is a plan view of the radiation detector 16 as viewed from the imaging surface side. In the present embodiment, the detection unit 44 and the detection unit 45 are provided on the side surface side of the casing 49, and the user is in the vicinity of the radiation detector 16 (within a range that can be detected by the detection unit 44 and the detection unit 45). It has a function of detecting a performed gesture. In the present embodiment, the detection unit 44 and the detection unit 45 use infrared sensors. However, the detection unit 44 and the detection unit 45 are not limited to infrared sensors, and are not particularly limited as long as they detect a gesture performed by a user based on a change in light. Not. It is preferable to use a detector that detects light based on a change in light in this manner, so that wireless communication can be set in a non-contact manner (without the user touching the radiation detector 16). Any contact type detector such as a touch sensor may be used. In the present embodiment, the detection unit 44 and the detection unit 45 are the same type of infrared sensor, but they may be different types of sensors.

  The display unit 46 has a function of notifying that the radiation detector 16 has shifted to a mode for setting wireless communication (network setting mode, details will be described later). As shown in FIG. It is provided on the side surface different from the side surface on which the detection unit 44 and the detection unit 45 of the casing 49 of the container 16 are provided. The position where the display unit 46 is provided is preferably a position where the user can easily see the display. In the present embodiment, as a specific example, display unit 46 is configured by an LED.

  The storage unit 42 has a function of storing a movement pattern (a gesture performed by a user) and wireless communication setting information in association with each other. Note that the storage unit 42 may be configured by a non-volatile memory so that stored setting information is retained even when the radiation detector 16 is powered off. In the present embodiment, the setting information represents a setting value (parameter). However, the present invention is not limited to this, and may be information regarding the setting value.

  Further, the radiation detector 16 of the present embodiment is provided with a power supply unit 48, and each of the above-described units and the like is operated by electric power supplied from the power supply unit 48. The power supply unit 48 incorporates a battery (a rechargeable secondary battery) so as not to impair the portability of the radiation detector 16, and supplies power from the charged battery to each unit. In FIG. 2, in order to prevent the drawing from becoming complicated, the wiring connecting the power supply unit 48 and each unit is omitted.

  Thus, in the radiation detector 16 of this Embodiment, the radiographic image according to the irradiated radiation is image | photographed. The radiographic image capturing operation by the radiation detector 16 of the present embodiment is executed without synchronizing with the radiation irradiation by the radiation generator 14. As a method of capturing a radiographic image without synchronizing with the irradiation operation, a condition for starting charge accumulation in the TFT unit 30 is determined in advance, and the imaging timing is determined by using that condition as a trigger. A method of performing photographing (charge accumulation), or reading out charges accumulated in a predetermined pixel or a dedicated pixel, and determining that it is a photographing timing when the value of the read charge exceeds a predetermined threshold. Although the method of performing is mentioned, it does not specifically limit. In any of the methods, it is preferable to perform a reset operation for resetting the charge accumulated so far just before the start of charge accumulation for radiographic imaging.

  Next, a processing operation (hereinafter referred to as a wireless communication setting process) for setting wireless communication in the radiation detector 16 of the present embodiment will be described in detail with reference to the drawings. FIG. 6 is a flowchart illustrating an exemplary flow of a wireless communication setting process operation. When performing the wireless communication setting process, the program stored in advance in a predetermined area of the memory 36B in the control unit 36 is executed by the CPU 36A. 5 is performed when the power is turned on by the power supply unit 48, when the power is first turned on from the power supply unit 48 after the battery is replaced, However, it is not particularly limited. The timing may be set as desired by the user.

  In step 100, the user's gesture (change in infrared light) detected by the detection unit 44 and the detection unit 45 is input. In the next step 102, it is determined whether or not the detected user gesture is an operation for instructing a mode (network setting mode) for switching wireless communication settings. In the present embodiment, when the user wants to switch the network setting, such as when changing the control device 12 connected to the radiation detector 16 or when a new setting is desired, the user first takes a radiographic image. The radiation detector 16 is instructed to switch from the normal mode to the network setting mode for setting wireless communication. The user gives the instruction by a gesture. As a specific example, in the present embodiment, the mode switching operation is an operation in which the user shakes his / her hand from side to side (see FIG. 5). It should be noted that the gesture performed by the user when switching the mode in this way may be determined in advance as a specific mode switching operation, but the operation according to the currently set setting information (setting the setting information) The gesture performed by the user when doing so may be the mode switching operation.

  In step 102, if the detected user gesture is not a mode switching operation, the determination is negative and the process returns to step 100. On the other hand, if it is a mode switching operation, the determination is affirmative and the routine proceeds to step 104, where the mode is switched to the network setting mode.

  In the next step 106, the display unit 46 is turned on with the lighting pattern A in order to notify the user that the mode has been switched to the network setting mode. As a specific example, in the present embodiment, the display unit 46 is changed from a non-lighting state to a lighting state.

  Since the display unit 46 is turned on in this manner, the user recognizes that the radiation detector 16 has been switched to the network setting mode, and performs a gesture according to a desired setting in order to set wireless communication. In the present embodiment, the wireless communication setting B (setting for connecting to the control device 12B) corresponds to the pattern of movement of moving the hand back and forth (see FIG. 5), and the setting C (control device). The setting for connecting to 12C corresponds to a movement pattern of moving the hand to the left and right, and the correspondence is stored in the storage unit 42 in advance. Therefore, the user performs a gesture to move the hand back and forth (see FIG. 5) in order to set wireless communication to setting B, and in order to set to C, the user performs a gesture to move the hand to the left and right.

  Therefore, in step 108, it is determined whether or not the detection unit 44 and the detection unit 45 have detected such a user gesture. If it is not detected, it is denied and enters a standby state. On the other hand, if it is detected, it is affirmed and the process proceeds to step 110 to determine which movement pattern the detected gesture is. In the next step 112, Wireless communication setting information corresponding to the determined movement pattern is acquired from the storage unit 42. In the next step 114, the acquired wireless communication setting information is set in the wireless communication unit 40.

  In the next step 116, the display unit 46 is turned on with the display pattern B in order to notify the user that the setting of the wireless communication unit 40 has been completed. As a specific example, in the present embodiment, the display unit 46 is blinked a predetermined number of times and then turned off. In addition, how to turn on the display unit 46, such as the number of blinks, is not particularly limited as long as it can notify the user that the setting has been completed. For example, when the wireless communication unit 40 is set to the setting B, the setting is completed by blinking twice according to the setting information, such as blinking twice when setting the setting C, and blinking three times when setting the setting C. Along with this, the user may be notified of the setting information set.

  In the next step 118, the network setting mode is terminated, and in the next step 120, it is determined whether or not the present process is to be terminated. If not finished, the determination is negative and the process returns to step 100, and the detection unit 44 and the detection unit 45 enter a standby state until it is detected that the mode switching operation has been performed, and this processing is repeated. On the other hand, if the result is affirmative, this process is terminated.

  As described above, the radiation detector 16 of the radiographic imaging system 10 according to the present exemplary embodiment previously stores a movement pattern (a gesture performed by the user) and wireless communication setting information in the storage unit 42. In the network setting mode, the control unit 36 determines which movement pattern the user gesture detected by the detection unit 44 and the detection unit 45 corresponds to, and corresponds to the corresponding movement pattern. The wireless communication setting information to be acquired is acquired and set in the wireless communication unit 40.

  Thus, since the setting of the wireless communication unit 40 is performed according to the user's gesture, the setting according to the user's intention can be appropriately performed. In addition, since the settings can be made without being connected to the control device 12 or the like without going through a wired network, convenience for the user is improved. Further, as shown in FIG. 1, the radiation detector 16 can be used only in wireless communication in a plurality of rooms (radiation image capturing rooms).

  Moreover, in the radiation detector 16 of this Embodiment, the gesture which the user performed near the housing | casing 49 of the radiation detector 16 is detected by the detection part 44 and the detection part 45, and setting of wireless communication is performed. Therefore, the setting can be performed without the user touching the radiation detector 16.

  In the above embodiment, the case of setting by storing the wireless communication setting information (ESSID) in the storage unit 42 has been described in detail, but the present invention is not limited to this. For example, the wireless communication setting information is not limited to the ESSID, but may be other identifiers such as an SSID depending on the frequency band and the situation of the radiographic imaging system 10. In addition, other setting information related to radiographic image capturing may be set, and the setting information generally set from the control device 12 such as the charge accumulation time of the TFT unit 30 is the same as the wireless communication setting process described above. It may be set for the radiation detector 16 by the above process.

  In addition, the user's gesture (movement pattern) shown as a specific example in the present embodiment is also an example, and other gestures may be used. However, in order to prevent false detection, the user's gesture cannot be performed. It is preferable to use a gesture that does not happen by the user.

  Moreover, in this Embodiment, although the detection part 44 and the detection part 45 are provided as a detection means which detects a user's gesture, the number of the detection parts provided in the radiation detector 16 is restricted to two in this way. It may be one or three or more. In order to prevent erroneous detection, it is preferable to provide a plurality. Further, the positions where the detection unit 44 and the detection unit 45 are provided are not limited to the positions shown in FIG.

  In the present embodiment, the detection unit 44 and the detection unit 45 have been described with respect to the case where the user detects a gesture of moving the hand. However, the present invention is not limited thereto, and the movement of a body part other than the hand may be detected. The movement of an object may be detected instead of the body part. Moreover, you may make it detect using a barcode reader etc.

  In addition, the configuration of the radiographic imaging system 10, the control device 12, the radiation generation device 14, the radiation detector 16 and the like described in the present embodiment is an example, and the situation is within the scope not departing from the gist of the present invention. Needless to say, it can be changed accordingly.

  An example of the flow of wireless communication setting processing (FIG. 6) described in this embodiment is also an example, and it goes without saying that it can be changed depending on the situation without departing from the gist of the present invention.

  In this embodiment, the case where X-rays are applied as the radiation of the present invention has been described. However, the present invention is not limited to this, and γ-rays or the like may be applied.
