  However, for example, when photographing in a supine position, an electronic cassette with the surface to be irradiated facing up is inserted and placed between the patient lying on the bed and the bed, and then radiation is applied from above. On the other hand, in the techniques described in Patent Documents 1 and 2, the display unit is arranged on the back side (the opposite side to the irradiated surface) of the casing of the electronic cassette. When confirming by displaying on the screen, it is necessary to pull out the electronic cassette from between the bed and the patient, and to invert the top and bottom of the electronic cassette so that the display unit faces upward. In addition, when taking an image again, it is necessary to reverse the top and bottom of the electronic cassette so that the irradiated surface side of the housing faces up, and to insert it again between the bed and the patient. It is. In addition, if the display surface of the display unit is increased in size for the purpose of improving the visibility of display information, the size of the electronic cassette case increases accordingly, and the handling property of the electronic cassette is greatly reduced. is there.

  Further, in the configuration shown in FIG. 2 of Patent Document 3, the display unit is arranged on the irradiated surface side in the casing of the electronic cassette. Therefore, when the captured radiation image is displayed on the display unit and confirmed. Although it is not necessary to insert / remove the electronic cassette or to invert the top / bottom, the display surface of the display unit may come into contact with the patient's body depending on the imaging region, making it difficult to confirm the radiation image. In addition, since the display unit needs to be provided outside the radiation detection area within the irradiated surface of the electronic cassette housing, if the display surface of the display unit is to be increased in size, the electronic cassette housing is accordingly accompanied. However, there is a problem that the handling of the electronic cassette is greatly reduced.

  Further, the configuration shown in FIG. 3 of Patent Document 3 is different from the configuration shown in FIG. 2 of Patent Document 3 in that the display unit is detachable from the electronic cassette body, but in the recess of the housing. The position of the display unit in the state of being inserted into the device is the same as the configuration shown in FIG. In addition to being difficult, if the display surface of the display unit is to be increased in size, there is a problem in that the casing of the electronic cassette increases in size and the handling property of the electronic cassette is greatly reduced. .

  Further, in FIG. 4 of Patent Document 3, the display unit is configured as a separate casing independent of the electronic cassette and wirelessly communicates with the electronic cassette. However, the display unit of a separate casing independent of the electronic cassette is displayed. In order to maintain the image or the like in a state where it can be easily visually recognized and located at a position close to the electronic cassette, some kind of support mechanism is required as in the technique described in Patent Document 4 described below. Become. And when a display part is made to support a support mechanism, since the ease of movement falls compared with an electronic cassette main body, there exists a problem that the portability of an electronic cassette is impaired. In addition, since the support mechanism cannot be installed at a position close to the electronic cassette at the destination of the electronic cassette, there is a possibility that the position of the electronic cassette and the position of the display unit are separated. In that case, a display unit is provided. There is also a problem that the advantage is lost.

  In addition, the electronic cassette is excellent in portability, and it has the feature that the same electronic cassette can be used for shooting in a different shooting room as well as shooting in a standing position or standing position. In the technique described in Patent Document 4, the display unit is separate from the electronic cassette, and the display unit is fixed at a position adjacent to the body surface of the subject by the support mechanism. The movement of the part is not easy, and there is a problem that the portability of the electronic cassette is impaired as in the configuration shown in FIG. In addition, since the support mechanism cannot be installed at a position close to the electronic cassette at the destination of the electronic cassette, there is a possibility that the position of the electronic cassette and the position of the display unit are separated. In that case, a display unit is provided. There is also a problem that the advantage is lost.

  Further, in the technique described in Patent Document 5, the display unit is separate from the electronic cassette, and the display unit is connected to the electronic cassette by legs that can change the mounting angle. Although the display unit can be moved freely, there is a problem that the legibility and the display unit move together with the electronic cassette body when the electronic cassette is moved, so that the handleability deteriorates.

  The present invention has been made in consideration of the above facts, and is a portable type capable of realizing an increase in the size of the display surface of a display unit capable of displaying information such as a radiation image without incurring a decrease in handleability and portability. It is an object to obtain a radiation image forming apparatus.

  In order to achieve the above object, a portable radiographic image forming apparatus according to the first aspect of the present invention detects the radiation that has passed through the subject and applied to the irradiated surface of the housing, and represents the distribution of the irradiation dose. Image output means for outputting radiographic image data, storage means for storing radiographic image data output from the image output means, and a display having a larger area than the irradiated surface and capable of being developed outside the housing A display unit that is provided in the casing so as to be capable of being stored in a storage unit that is provided in the casing and has an area that is less than or equal to the irradiated surface, or that can fold the display surface. Display control means for displaying arbitrary information including a radiation image in which data is stored on the display surface of the display means.

  The portable radiographic image forming apparatus according to the first aspect of the present invention detects radiation irradiated to the irradiated surface of the casing through the subject, and outputs radiation image data representing the distribution of the irradiation radiation dose. An image output means is provided, and the radiographic image data output from the image output means is stored in the storage means.

In the state where the housings 70 are arranged, the storage units are arranged through the openings 126 so that the display surfaces face each other and the partial display unit 120A is positioned above the partial display unit 120B in the storage unit 122. Each is inserted in 122. In the first embodiment, since the shape of the display area provided on the display surface is rectangular, an LCD is suitable as the display device. However, a display device other than the LCD may be used. Further, the side surface of the partial display portion 120A that closes the opening 126 in a state where the partial display portions 120A and 120B are respectively stored in the storage portion 122 (the state shown in FIGS. 4A and 5A). A pair of gripping portions 128 are attached.

  In addition, a pair of side surfaces along the insertion direction into the storage unit 122 of the partial display unit 120B are provided with grooves 121 along the longitudinal direction of the side surface, and the storage unit 122 of the partial display unit 120A. Brackets 123 are respectively attached to the pair of side surfaces along the insertion direction into the end portion which becomes the front end side when inserted into the storage portion 122 (which becomes the rear end side when pulled out from the storage portion 122). Yes. The bracket 123 extends downward (partial display portion 120B side) and is omitted from illustration, but its tip is bent into the groove 121 and enters the groove 121.

The display surface can be relatively moved along the direction of insertion / extraction to the storage portion 122 while maintaining a substantially parallel state.

  The display unit 120 is slid in the direction in which the partial display unit 120A is pulled out from the storage unit 122 of the housing 70 (in the direction of arrow D in FIG. 5) by a photographer (radiologist) who holds the pair of grip units 128. When the unfolding operation is performed, first, the tip end portion of the bracket 123 slides in the groove 121 in the pulling direction, so that a partial display is performed as shown in FIGS. 4B and 5B. Only the portion 120 </ b> A slides and is pulled out of the storage portion 122. Further, when the above-described unfolding operation is continued even after the distal end portion of the bracket 123 slides and moves to the end of the groove 121 along the pull-out direction, the pull-out force due to the unfolding operation causes the bracket 123 to move from the partial display portion 120A. By being transmitted to the partial display unit 120B through the partial display unit 120B, the partial display unit 120B is also slid in the direction of being pulled out from the storage unit 122 together with the partial display unit 120A (see also FIG. 4C). Then, by continuing the unfolding operation thereafter, as shown in FIG. 5C, the display surfaces of the partial display portions 120A and 120B are outside the housing 70 (of the side surface to which the handle portion 124 is attached). It is in a state of being expanded in the outer space). Hereinafter, the positions of the partial display units 120A and 120B in this state are referred to as displayable positions.

The display unit 120 has the total area of the display surface developed outside the housing 70 (the partial display units 120A, 120A, 120B deployed outside the housing 70, respectively) in a state where the partial display units 120A, 120B are moved to the displayable position. The size and the like of the partial display portions 120A and 120B are determined in advance so that the total area of the display surface of 120B) is larger than the area of the irradiated surface 72 of the electronic cassette 22. By moving 120B to the displayable position, a display surface having a larger area than the irradiated surface 72 is formed outside the housing 70 by the partial display portions 120A and 120B moved to the displayable position.

Is separated from the casing 70 of the electronic cassette 22).

  In addition, in a state where the partial display units 120A and 120B are located at the displayable positions, the pair of gripping units 128 are gripped by the photographer (radiologist) or the partial display in which the pair of gripping units 128 are attached. When the storage operation for sliding (sliding) the partial display unit 120A in the direction (arrow E direction in FIG. 5) to be inserted into the storage unit 122 is performed by directly pressing the side surface of the unit 120A, As the tip end of the bracket 123 slides in the insertion direction in the groove 121, only the partial display portion 120A is slid in the insertion direction. Further, when the above-described storage operation is continued even after the distal end portion of the bracket 123 slides and moves to the end of the groove 121 along the insertion direction, the pressing force by the storage operation causes the bracket 123 to move from the partial display portion 120A. Is transmitted to the partial display unit 120B through the sliding movement in the direction in which the partial display unit 120B is inserted into the storage unit 122 together with the partial display unit 120A, and the partial display units 120A and 120B are moved to the storage unit 122. Each is housed (in the state shown in FIGS. 4A and 5A). Hereinafter, the positions of the partial display portions 120A and 120B in this state are referred to as storage positions. As a result, the partial display units 120A and 120B that form a display surface having a larger area than the irradiated surface 72 in a state of being moved to the displayable position have an area viewed from the irradiated surface 72 side of the irradiated surface 72 or less. It is stored in the storage unit 122.

  Moreover, as shown in FIG. 4, the lead sheet 130 is affixed on the back surface (surface opposite to the irradiated surface 72 side) of the partial display portion 120B. By providing the lead sheet 78 described above, the backscattering of radiation can be reduced and radiation deterioration of the display unit 120 stored in the storage unit 122 can be suppressed, but the lead sheet 130 is a lead sheet. 78 is provided for the purpose of assisting in reducing absorption of radiation backscattering.

When charges are stored in the storage capacitors 88 of the individual pixel portions 94, the TFTs 90 of the individual pixel portions 94 are sequentially turned on in units of rows by a signal supplied from the gate line driver 100 via the gate wiring 96. The charge stored in the storage capacitor 88 of the pixel section 94 for which is turned on is transmitted as a charge signal through the data wiring 98 and input to the signal processing section 102. Accordingly, the charges accumulated in the storage capacitors 88 of the individual pixel portions 94 are sequentially read out in units of rows.

  Although not shown, the signal processing unit 102 includes an amplifier and a sample-and-hold circuit provided for each data line 98, and the charge signal transmitted through each data line 98 is amplified by the amplifier. It is held in the sample hold circuit. In addition, a multiplexer and an A / D converter are connected in order to the output side of the sample and hold circuit, and the charge signals held in the individual sample and hold circuits are input to the multiplexer in order (serially) for A / D conversion. The digital image data is converted by the device. An image memory 104 is connected to the signal processing unit 102, and image data output from the A / D converter of the signal processing unit 102 is sequentially stored in the image memory 104. The image memory 104 has a storage capacity capable of storing image data for a plurality of frames, and image data obtained by imaging is sequentially stored in the image memory 104 each time a radiographic image is captured. The image memory 104 corresponds to the storage unit according to the present invention.

  A cassette control unit 106 is connected to the image memory 104. The cassette control unit 106 includes a microcomputer and the like, and includes a CPU 106A, a memory 106B including a ROM and a RAM, and a non-volatile storage unit 106C including an HDD, a flash memory, and the like, and an information display for performing an information display process described later. The program is stored in the storage unit 106C. Although not shown, the cassette control unit 106 is connected to the gate line driver 100 and the signal processing unit 102 described above, and charges are read from the individual pixel units 94 by the gate line driver 100 and the signal processing unit 102. To control. Further, the cassette control unit 106 is connected with a display unit 120, an input unit 108, a drawer sensor 110, and a wireless communication unit 112.

  The cassette control unit 106 displays information such as a radiation image represented by the image data stored in the image memory 104 on the display unit 120 by performing an information display process described later. Thus, the cassette control unit 106 corresponds to the display control means according to the present invention. In the present embodiment, the input unit 108 includes a touch panel provided on the display surface of the display unit 120. When the photographer operates the input unit 108 (touch panel), information corresponding to the operation is cassette controlled. Input to the unit 106. The drawer sensor 110 is a sensor that is provided in the storage unit 122 and detects whether or not the display unit 120 has been pulled out from the storage unit 122. The detection result of the drawer sensor 110 is also input to the cassette control unit 106. In addition, a wireless antenna 114 is connected to the wireless communication unit 112, and the wireless communication unit 112 performs wireless communication via the wireless network 114 with other devices constituting the same radiographic imaging system 18 via the wireless network 28. Do. The wireless communication with other devices by the wireless communication unit 112 may be optical wireless communication using infrared rays or the like instead of normal wireless communication using radio waves.

  The electronic cassette 22 includes a battery 116, and the various circuits described above (the gate line driver 100, the signal processing unit 102, the image memory 104, the cassette control unit 106, the display unit 120, the input unit 108, and the wireless communication unit 112). Etc.) is operated by the electric power supplied from the battery 116. In the present embodiment, a secondary battery that is charged by power supplied from the power supply unit 63 of the cradle 24 is used as the battery 116, but the present invention is not limited to this, and a primary battery is used as the battery 116. Alternatively, a power supply unit that is always connected to a commercial power supply and that rectifies and transforms the power supplied from the commercial power supply to supply power to various circuits may be provided instead of the battery 116.

  Next, the operation of the first embodiment will be described. In the first embodiment, the electronic cassette 22 is moved and positioned to the position 58 or the position 60 in the radiation imaging room 42 according to the posture at the time of radiographic image capturing. The electronic cassette 22 according to the first embodiment is Since the display unit 120 can be stored in the storage unit 122 in the housing 70, when the electronic cassette 22 is moved / positioned to the position 58 or 60, or in another imaging room, operating room, or radiographic imaging device When the electronic cassette 22 is taken out from the radiation imaging room 42 for use in radiography in a vehicle equipped with a camera, the above-described storage operation is performed to store the display unit 120 in the storage unit 122 in the housing 70. Thus, it is possible to prevent the display unit 120 from obstructing the movement of the electronic cassette 22.

  Further, the electronic cassette 22 according to the first embodiment performs an unfolding operation of sliding the partial display unit 120A of the display unit 120 in the direction of pulling out from the storage unit 122 in the housing 70, and displays the partial display units 120A and 120B. By moving it to a possible position, the display surface of the display unit 120 can be expanded outside the housing 70, so that the unfolding operation for expanding the display surface outside the housing 70 can be easily performed, and handling is also easy. It is good. When the above-described unfolding operation is performed, the display surface of the display unit 120 is unfolded into a space outside the side surface of the housing 70 where the handle portion 124 is provided. Since the adjustment is performed by gripping the handle portion 124, the space is usually a space where no other object exists, and it is difficult to expand the display surface of the display unit 120 due to interference of the other object. Can be prevented.

  Further, the drawing of the display unit 120 from the storage unit 122 is limited to the displayable position shown in FIG. 5C by the stopper 125, so that the display unit 120 is not separated from the housing 70. After the electronic cassette 22 is moved and positioned to a desired position, the partial display portions 120A and 120B are pulled out from the storage portion 122 to the displayable position by the above-described unfolding operation, and the display surface of the display portion 120 is moved. Even when deployed outside the housing 70, the display unit 120 is supported by the housing 70 and is maintained in the positional relationship shown in FIG. Therefore, a support mechanism or the like for supporting the display unit 120 is unnecessary, and it is possible to avoid the handling property and portability of the electronic cassette 22 from being lowered by providing the display unit 120. Further, when the patient as a subject is located at the position indicated by the broken line in FIG. 4 with respect to the casing 70 of the electronic cassette 22, the display surface of the display unit 120 is expanded outside the casing 70. Thus, the display surface of the display unit 120 can be prevented from being in contact with the patient's body or the display surface of the display unit 120 can be prevented from being hidden by the patient's body. Since the display surface is larger than the irradiated surface 72 of the electronic cassette 22, the photographer can surely view information such as a radiographic image displayed on the display unit 120. Furthermore, since the display surface of the display unit 120 is larger than the irradiated surface 72 of the electronic cassette 22, it is possible to simultaneously display various images on the display surface of the display unit 120, as will be described later. Become.

  Next, radiographic image capturing in the RIS 10 will be described. When a doctor or a radiographer requests imaging of a radiographic image via the terminal device 12, information for identifying a patient to be imaged (for example, a patient ID), information on an imaging region, an imaging posture, etc. 12 is input. In addition, when a patient tag in which a patient ID is recorded is carried (or attached) to an individual patient, input of information for specifying the patient is performed on the patient tag recorded in the patient tag carried by the patient to be photographed. The ID is formed by reading the ID by a reading device connected to the terminal device 12. The radiographic image capturing request made via the terminal device 12 is transmitted to the RIS server 14 together with each piece of information input to the terminal device 12, and is received by the RIS server 14.

  When receiving the radiographic image capturing request from the terminal device 12, the RIS server 14 refers to the radiographic image capturing schedule in each of the already registered radiographic image capturing systems 18, and captures the radiographic image related to the received imaging request. Is selected with which radiographic image capturing system 18 is performed, and the date and time when the selected radiographic image capturing system 18 captures the radiographic image is determined. Then, necessary information such as patient attribute information is read from the RIS database, and the read information and the determined imaging date and time are added to the information received from the terminal device 12 and transmitted to the console 26 of the selected radiographic imaging system 18. .

  Each time the console 26 receives the above information from the RIS server 14, the console 26 stores the received information in the storage unit 66C, and the information stored in the storage unit 66C in accordance with an instruction from the radiographer (radiologist) On the display 67 as the imaging schedule and specific imaging contents of each imaging (for example, the name of the patient who performs imaging, the imaging part, the posture at the time of imaging, the standard driving condition of the radiation tube uniquely determined from the imaging part, etc.) To do. Further, the console 26 transmits to the radiation generator 20 imaging condition information representing imaging conditions in radiography to be performed from now on when imaging radiographic images. Thereby, the radiation source control unit 32 of the radiation generation apparatus 20 controls the radiation source moving unit 38 so that the radiation source 30 is located at a position corresponding to the posture at the time of photographing specified by the received photographing condition information.

  When radiographing is performed, the radiographer (radiologist) checks the radiographing site, radiographing posture, radiation tube driving conditions, and the like on the console 26, and then, in the radiographic room 42, the radiographer responds to the radiographing posture. The electronic cassette 22 is moved / positioned to a position (position 58 or position 60), the name is confirmed with respect to the patient himself / herself to be photographed, and the patient to be photographed is positioned according to the posture at the time of photographing (position 48 or position 50). A series of preparatory work such as fine adjustment of the position of the radiation source 30 is performed as necessary. When the series of preparation work is completed, the exposure switch 34 is turned on.

  Thereby, the radiation source 30 generates and emits a dose of radiation according to the radiation tube driving conditions included in the imaging condition information received by the radiation generator 20 from the console 26, and the radiation emitted from the radiation source 30. Irradiates the irradiated surface 72 of the electronic cassette 22 through the patient. In the electronic cassette 22, after the radiation irradiated to each part in the irradiated surface 72 is converted and accumulated into charges by the radiation detector 76, the charges accumulated by the gate line driver 100 and the signal processing unit 102 are read out. Is converted into radiation image data and stored in the image memory 104.

  The radiographic image data stored in the image memory 104 is transmitted from the electronic cassette 22 to the console 26 via the wireless network 28 and stored in the storage unit 66 </ b> C of the console 26. The radiographic image data stored in the storage unit 66C is displayed on the display 67 for confirmation of the captured radiographic image, and is also transferred to the RIS server 14 and stored in the RIS database. As a result, the captured radiographic image is displayed on the display of the terminal device 12, and the doctor can perform radiogram image interpretation, diagnosis, and the like.

  By the way, if the patient moves during radiographic image capture and the subject is blurred on the radiographic image, it is necessary to perform radiographing again. Therefore, the photographer must check whether the subject is blurred on the radiographic image. It is necessary to confirm. In addition, when taking a radiographic image of the same part of the same patient in the past, the photographer refers to the radiographic image taken in the past to facilitate the interpretation of the radiographic image by the doctor. It is necessary to match the imaging range (positioning) in this imaging as much as possible with the radiographic images captured in the past. Further, for example, the initially designated posture at the time of imaging is standing, but the patient who has arrived at the radiation imaging room 42 is in a state where imaging in the standing position is a burden (for example, an injured leg). For this reason, it may be desirable to change the posture during shooting. Further, it may be necessary to change the driving conditions of the radiation tube.

  Although the confirmation of the captured radiographic image, the reference of the radiographic image captured in the past, the change of the imaging posture and the driving condition of the radiation tube can be performed by operating the console 26, the console 26 Since it is generally installed outside the radiography room 42 (for example, another room adjacent to the radiography room 42), in the above case, the radiographer is in the middle of preparation work or every time imaging is performed. 42 and the installation location of the console 26 need to be reciprocated, and there is a problem that the work efficiency is very complicated and poor. There is also a problem in that the accuracy of adjustment of the imaging range is not sufficient because the imaging range (positioning) cannot be adjusted while referring to radiographic images taken in the past.

  In order to solve these problems, the electronic cassette 22 according to the present embodiment is provided with a display unit 120, which confirms a captured radiographic image, references a radiographic image captured in the past, an imaging posture and radiation. When the tube driving condition is changed or there is a possibility, the photographer holds the grip portion 128, pulls out the display portion 120 from the housing 70 (the storage portion 122) of the electronic cassette 22, and displays the display portion 120. The display surface is expanded outside the housing 70. When this operation is performed, the drawer sensor 110 detects that the display unit 120 has been pulled out, and the cassette controller 106 of the electronic cassette 22 performs information display processing shown in FIG. 6 using this as a trigger.

  In this information display processing, first, in step 300, various types of information to be displayed on the display unit 120 (for example, the patient ID and name of a patient to be imaged, an imaging region, an imaging history of a radiographic image, an attitude at the time of imaging, a tube voltage of the radiation tube) , Tube current, etc. (hereinafter, these pieces of information are collectively referred to as “RIS information”) by requesting the console 26 to transmit RIS information by transmitting information requesting transmission of the RIS information to the console 26 via the wireless communication unit 112. To do. In the next step 302, it is determined whether or not any information has been received from another device. When determination is denied, it transfers to step 304, and it is determined whether some information was input via the input part 108 which consists of a touch panel. When this determination is negative, the process proceeds to step 306, and it is determined whether or not the drawer sensor 110 detects that the display unit 120 is stored in the storage unit 122. If this determination is also negative, the process returns to step 302, and steps 302 to 306 are repeated until any determination is affirmed.

  When the console 26 receives information requesting transmission of RIS information from the electronic cassette 22, it reads information related to imaging to be performed from the storage unit 66 </ b> C, edits the read information as RIS information, and transmits it via the wireless communication unit 59. Transmit to the electronic cassette 22. When the RIS information is received by the wireless communication unit 112 of the electronic cassette 22 and input to the cassette control unit 106, the determination in step 302 is affirmed and the process proceeds to step 308. In step 308, the type of information received is determined. Branch off. When the received information is the RIS information received from the console 26, the process proceeds from step 308 to step 310, and first the RIS information received from the console 26 is stored in the memory 10B.

  In the next step 312, the RIS information received from the console 26 is displayed on the display surface of the display unit 120 as an RIS information display / correction screen. As shown in FIG. 7A, the RIS information display / correction screen displays the contents of the received RIS information (patient ID and name of the patient, radiographic imaging history, imaging location, imaging posture, and tube voltage of the radiation tube. , Tube current, etc.), and some items (eg, posture during radiography, tube voltage of the radiation tube, tube current, etc.) can be entered by the radiographer (radiographer). By displaying this screen on the display surface of the display unit 120, it is possible to grasp the contents of radiographic image capturing to be performed.

  In addition, since the patient ID and name are displayed on the above screen, for example, the name of the patient to be imaged is confirmed by confirming the name with the patient and comparing the confirmed name with the name displayed on the screen. Whether or not there is a difference can be surely confirmed in the radiation imaging room 42. In the above screen, the shooting posture, radiation tube voltage, tube current, etc. are displayed so that the photographer can input correction instructions. The photographer must check the contents of these items and make corrections. If it is determined that the radiographing room 42 and the installation location of the console 26 are reciprocated by inputting a correction instruction via the input unit 108 formed of a touch panel, the posture during imaging and the tube voltage of the radiation tube It becomes possible to change the tube current and the like.

  In the next step 314, information for requesting data of related radiographic images captured in the past is generated, and the patient ID and the imaging region included in the received RIS information are added to the generated information and transmitted to the console 26. By doing this, the console 26 is requested to transfer data of radiographic images that have been imaged in the past and that have the same patient and imaged part as the current image. If the process of step 314 is performed, it will return to step 302 and will repeat step 302-step 306.

  Upon receiving the above information from the electronic cassette 22, the console 26 transfers the received information to the RIS server 14 to request the RIS server 14 for data of related radiographic images taken in the past, and the RIS server 14 The RIS database is searched using the patient ID and the imaging region added to the information received from the console 26 as keys. If the corresponding radiographic image data is stored in the RIS database, the RIS server 14 reads out the corresponding radiographic image data from the RIS database and transmits it to the console 26 of the request source. When the console 26 receives the radiation image data requested from the electronic cassette 22 from the RIS server 14, the console 26 transmits the received radiation image data to the requesting electronic cassette 22.

  When the radiographic image data is received by the electronic cassette 22, the determination in step 302 of the information display process (FIG. 6) is affirmed and the process proceeds to step 308. The received information is the radiographic image received from the console 26. If it is data, the process branches from step 308 to step 316. In step 316, the radiographic image data received from the console 26 is stored in the memory 106B. In step 318, based on the data received from the console 26, the radiographic image represented by the data (the radiographic image captured in the past with the same imaging and the same patient and imaging site) is displayed on the display unit 120.

  In this embodiment, since the display surface of the display unit 120 has a larger area than the irradiated surface 72 of the electronic cassette 22, in step 318, as shown in FIG.・ By additionally displaying the radiation image represented by the received data on the display surface of the display unit 120 on which the correction screen is already displayed, the character information (RIS information display / correction screen) and the image (taken in the past and this time Radiation images related to imaging) are simultaneously displayed on the display surface of the display unit 120. This display corresponds to the invention described in claims 7 and 9. Thereby, the photographer can grasp the photographing range when the same photographing part of the same patient was photographed in the past by referring to the radiographic image displayed on the display unit 120, and the grasped photographing. It is possible to adjust the imaging range in the current imaging so as to match the range as much as possible without reciprocating between the radiation imaging room 42 and the installation location of the console 26. In addition, the radiographic image taken in the past can be adjusted more accurately than in the case where radiographic images taken in the past are displayed on the display 67 of the console 26 installed outside the radiographic room 42. it can.

  In addition, the radiograph taken in the past and related to the current radiograph is displayed on the display surface of the display unit 120 at the same time as the RIS information display / correction screen, so that the radiographer can take an image with reference to the displayed radiographic image. It is also possible to consider modifying the conditions, which improves the convenience of the photographer. In addition, since the radiation image displayed at this time is a radiation image taken in the past and the same imaging as the current imaging and the patient and the imaging site, the patient name, patient ID, and radiation displayed on the RIS information display / correction screen are displayed. The imaging history of the image is also attribute information of the radiographic image displayed simultaneously on the display surface of the display unit 120, and the above display corresponds to the invention according to claim 8, but the attribute information of the radiographic image As an alternative, photographing conditions such as tube voltage and tube current at the time of past photographing may be displayed. In this case, it becomes easy to match the photographing conditions such as the tube voltage and the tube current in the current photographing with those in the past photographing, and the convenience of the photographer is further improved.

  When the process of step 318 is performed as described above, the process returns to step 302, and steps 302 to 306 are repeated again. When there is no radiographic image related to the current radiographing that has been taken in the past, the corresponding radiographic image data is not transmitted from the RIS server 14 to the console 26, and the radiographic image data is also sent from the console 26 to the electronic cassette 22. Is not transmitted, the processing of steps 316 and 318 is not performed, and the radiographic image captured in the past and related to the current imaging is not displayed. In addition, when the RIS server 14 receives an imaging request from the terminal device 12, the RIS server 14 determines whether or not there is a radiographic image captured in the past and related to the current imaging, which corresponds to the result of the determination. The image presence / absence information to be transmitted is added to the information transmitted from the RIS server 14 to the console 26, and the image presence / absence information is also added to the RIS information transmitted from the console 26 to the electronic cassette 22. Based on the image presence / absence information added to the RIS information received from H.26, the radiographic image data is requested only when there is a radiographic image captured in the past and related to the current imaging (in step 314). Process).

  In addition, while the RIS information display / correction screen is displayed on the display unit 120, the input unit 108 including a touch panel is operated by the photographer, and the photographing conditions such as the posture at the time of photographing, the tube voltage of the radiation tube, and the tube current are set. If information for instructing correction is input, the determination in step 304 is affirmed and the process proceeds to step 326, where it is determined whether or not the input information is information for instructing correction of imaging conditions. In this case, the determination is affirmed, the process proceeds to step 328, and the content of the item instructed to be corrected by the input information among the RIS information stored in the memory 106B is corrected according to the instruction. In the next step 330, the corrected RIS information is transmitted to the console 26. In the next step 332, it is determined whether or not enlargement display of the radiation image has been instructed. In this case, this determination is negative and the process proceeds to step 336. In step 336, it is determined whether or not the confirmation of the radiation image has been completed. In this case, this determination is also denied, the process returns to step 302, and steps 302 to 306 are repeated again.

  When the RIS information corrected by the photographer's instruction is received from the electronic cassette 22, the console 26 edits the RIS information received from the electronic cassette 22 into the imaging condition information and transmits the imaging condition information to the radiation generation apparatus 20, and the storage unit 66C. The information corresponding to the received RIS information is corrected based on the received RIS information. Thus, if the item corrected by the photographer's instruction is an item related to the radiation tube driving conditions such as the tube voltage and the tube current, the driving conditions according to the contents after the correction when the radiation from the radiation source 30 is emitted. When the radiation tube is driven and the item corrected by the photographer's instruction is the posture at the time of photographing, the radiation source moving unit 38 causes the radiation source 30 to move to a position corresponding to the posture at the time of photographing after correction. The movement of the radiation source 30 is controlled by the radiation source control unit 32. By the above processing, the photographer can correct the photographing conditions in the current photographing without reciprocating between the radiation photographing room 42 and the installation location of the console 26.

  Further, when the exposure switch 34 is pressed by the photographer, an input of an exposure instruction is notified from the radiation generator 20 to the electronic cassette 22. If the determination in step 302 is affirmed and the process proceeds to step 308, and if the received information is an exposure instruction input notification received from the radiation generation apparatus 20, the process branches from step 308 to step 320. When the exposure switch 34 is pressed, the radiation generator 20 emits radiation from the radiation source 30, and the radiation emitted from the radiation source 30 passes through the patient (subject) and is applied to the electronic cassette 22. In step 320, at the timing when the emission of radiation from the radiation source 30 is completed, the electric charge accumulated in the radiation detector 76 is read out, converted into radiation image data, and stored in the image memory 104. The RIS information received from the console 26 also includes information (for example, the number of simultaneous readout lines) that defines the readout conditions for readout of charges from the radiation detector 76, and the readout of charges from the radiation detector 76 is performed as described above. Is performed in accordance with the reading conditions specified by.

  In the next step 322, based on the fact that the display surface of the display unit 120 has a larger area than the irradiated surface 72 of the electronic cassette 22, as shown in FIG. A radiographic image represented by the image data stored in the memory 104 (a radiographic image obtained by the current imaging) is displayed on the display unit 120 at the same time as the radiographic image captured in the past and related to the current imaging. This display corresponds to the invention described in claims 2, 3, and 5. As a result, the photographer can confirm whether or not the photographing range in the current photographing is appropriate and whether or not the subject is blurred on the radiation image by referring to the radiation image displayed on the display unit 120. it can. In addition, the photographer confirms again whether or not the radiographing range of the two is significantly different by comparing the radiographic image obtained by the current radiographing with the radiographic image captured in the past. can do.

  Note that, in step 322, the radiographic image whose data is stored in the image memory 104 is not limited to being displayed on the display unit 120 as it is. After the noise is removed or various correction processes for correcting the pixel-to-pixel variation of the image data caused by the variation in the characteristics of the pixel portions 94 of the radiation detector 76 are performed, and then displayed on the display unit 120. You may do it. In the next step 324, the image data of the radiographic image obtained by the current imaging is transmitted to the console 26. The image data transmitted to the console 26 is stored in the storage unit 66C of the console 26, displayed on the display 67 for confirmation of the radiographic image, etc., transferred to the RIS server 14, and stored in the RIS database. It is used for radiogram image interpretation and diagnosis through the device 12. When the process of step 324 is completed, the process returns to step 302, and steps 302 to 306 are repeated again.

  Further, as shown in FIG. 7A, when a radiographic image obtained by the current imaging is displayed, a button 350 for instructing an enlarged display of the radiographic image is also displayed on the display surface of the display unit 120. Is displayed. When the radiographer wants to confirm in detail a part of the radiographic image obtained by the current radiographing, he or she selects the button 350 to instruct enlargement display, and then on the display surface of the location where detailed confirmation is desired. An enlarged display operation for pressing the position is performed. When this enlargement display operation is performed, the determination in step 304 is affirmed, the determination in step 326 is denied, and the determination in step 332 is affirmed, and the process proceeds to step 334, and the radiation stored in the image memory 104 After generating an enlarged display image for enlarging and displaying the indicated location at a larger display magnification based on the image data, the generated enlarged display image is already displayed as shown in FIG. 7D as an example. Instead of the past image being displayed, the image is displayed on the display surface of the display unit 120. This display corresponds to the invention described in claims 2 and 6. Thereby, the photographer can confirm the desired part in the radiographic image obtained by this imaging | photography more in detail.

  Note that the interface for displaying the enlarged display image is not limited to the above, and the photographer may be able to specify the display magnification, and the display range may be instructed to be scrolled with respect to the displayed enlarged display image. Also good. When the process of step 334 is performed, the process proceeds to step 336. In this case, this determination is denied, the process returns to step 302, and steps 302 to 306 are repeated again.

  When the confirmation of the radiographic image displayed on the display unit 120 is completed, the radiographer operates the input unit 108 formed of a touch panel and inputs information indicating the end of the radiographic image confirmation. In this case, the determination in step 304 is affirmed, the determinations in steps 326 and 332 are negated, the determination in step 336 is affirmed, and the process proceeds to step 338 to transmit RIS information corresponding to the next imaging to be performed. Request to console 26 and return to step 302. Then, by receiving the RIS information transmitted from the console 26 according to this request, the above-described sequence is repeated again.

  In addition, when the electronic cassette 22 is moved or when all the radiographic images scheduled for the day are completed, the photographer holds the grip portion 128 and presses the display portion 120 to enclose the housing of the electronic cassette 22. 70 (the storage unit 122) is stored. When this operation is performed, it is detected by the drawer sensor 110 that the display unit 120 has been accommodated, and the determination in step 306 is affirmed, whereby the information display process described above is terminated.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and description is abbreviate | omitted.

  FIG. 8 shows (a part of) an electronic cassette 22 according to the second embodiment. As shown in FIGS. 8B and 8C, the electronic cassette 22 according to the second embodiment is provided with a long sheet-like display unit 146 having flexibility. As shown in FIG. 8C, the display surface of the display unit 146 according to the second embodiment has a larger area than the irradiated surface 72 of the electronic cassette 22. Note that the display unit 146 is preferably electronic paper. One end of the display unit 146 in the longitudinal direction is attached to the take-up shaft 148, and the entire amount of the display unit 146 is located on one end of the housing 70 of the electronic cassette 22 where the handle 124 is attached. A storage space (storage unit 150) in which the display unit 146 and the winding shaft 148 can be stored in a state of being wound around the winding shaft 148 is provided. The take-up shaft 148 is disposed in the storage unit 150 and is rotatably supported by the housing 70. Although not shown, the storage unit 150 has a rotation mechanism that rotates the winding shaft 148 in the direction of winding the display unit 146 by the biasing force of the biasing means, and the entire amount of the display unit 146 from the winding shaft 148. When the take-up shaft 148 is pulled out, the rotation of the take-up shaft 148 is prevented. When the take-up shaft 148 is further pulled from this state via the display unit 146, the state of preventing the take-up shaft 148 from rotating is released. A latch mechanism is provided.

  A protective member 152 having a rectangular cross section and a long cross section is attached to the end of the display portion 146 opposite to the side attached to the take-up shaft 148. , Gripping portions 154 are attached to two places on the side surface. The protective member 152 has a tension applied to the gripping part 154 when the gripping part 154 is gripped and the gripping part 154 is pulled in a direction in which the display part 146 is pulled out from the winding shaft 148 against the rotational force of the rotation mechanism. The display unit 146 has a function of preventing damage to the display unit 146 by uniformly transmitting the force to the display unit 146. In addition, an opening 126 is provided on a side surface of the housing 70 of the electronic cassette 22 to which the handle portion 124 is attached, and a portion corresponding to the opening 126 in the storage portion 150 is caused by the rotational force of the rotation mechanism. A stopper (not shown) is provided to prevent the protective member 152 from further entering the storage portion 150 from the position shown in FIG.

  In the display unit 146 according to the second embodiment, the grip unit 154 is gripped, and the display unit 146 is pulled out from the storage unit 150 of the housing 70 against the rotational force of the rotation mechanism (the arrow D in FIG. 8). The display unit 146 is pulled out from the take-up shaft 148, and the rotation of the take-up shaft 148 by the rotation mechanism is blocked by the latch mechanism. The display surface is expanded to the side of the outside where the handle portion is provided, and the display portion 146 is exposed to the outside of the housing 70 (the state shown in FIG. 8C). In addition, when the storing operation for further pulling the winding shaft 148 is performed via the grip portion 154, the protective member 152, and the display unit 146 from this state, the rotation blocking state of the winding shaft 148 by the latch mechanism is released, and the display unit When the take-up shaft 148 is rotated by the rotation mechanism in the direction to take up 146, the display unit 146 is taken up by the take-up shaft 148 and stored in the storage unit 150 (see FIG. 8A).

  The display unit 146 corresponds to display means according to the present invention (more specifically, display means according to claims 12 and 17). Further, in the second embodiment, the lead sheet 130 is omitted, and the function of reducing absorption of radiation backscattering is realized by the lead sheet 78.

  Next, the operation of the second embodiment will be described. Since the electronic cassette 22 according to the second embodiment can store the display unit 146 in the storage unit 150 in the housing 70, when the electronic cassette 22 is moved / positioned to the position 58 or the position 60, other image capturing is performed. When the electronic cassette 22 is taken out of the radiation imaging room 42 for use in radiography in a room, operating room, or vehicle equipped with a radiographic imaging device, the above-described storage operation is performed to display the display unit 146 in the housing 70. The display unit 146 can be prevented from obstructing the movement of the electronic cassette 22 by being stored in the internal storage unit 150.

  Further, the electronic cassette 22 according to the second embodiment expands the display surface of the display unit 146 to the outside of the housing 70 by performing an unfolding operation to pull the display unit 146 in a direction in which the display unit 146 is pulled out from the storage unit 150 in the housing 70. Therefore, the unfolding operation for unfolding the display surface to the outside of the housing 70 can be easily performed, and the handleability is also good. When the above-described unfolding operation is performed, the display surface of the display unit 146 is unfolded into the space outside the side surface of the housing 70 where the handle portion 124 is provided. Since the adjustment is performed by gripping the handle portion 124, the above space is usually a space where no other object exists, and it is difficult to develop the display surface of the display unit 146 due to the interference of the other object. Can be prevented.

When the entire amount of the display unit 146 is pulled out from the winding shaft 148, the rotation of the winding shaft 148 by the rotation mechanism is blocked by the latch mechanism. Thus, after the electronic cassette 22 is moved and positioned to a desired position, the entire amount of the display unit 146 is pulled out from the winding shaft 148 by the above-described unfolding operation, and the display surface of the display unit 146 is unfolded outside the housing 70. In this case, since the display unit 146 is flexible, the display unit 146 is suspended from the housing 70 of the electronic cassette 22, but is still displayed on the display surface of the display unit 146. Information such as images can be confirmed. Therefore, a support mechanism or the like that supports the display unit 146 is not necessary, and the provision of the display unit 146 can prevent the handling property and portability of the electronic cassette 22 from being lowered.

  Further, the display surface of the display unit 146 is expanded outside the housing 70 even when the patient as the subject is located at the position indicated by the broken line in FIG. 4 with respect to the housing 70 of the electronic cassette 22. Thus, it can be prevented that the display surface of the display unit 146 is in contact with the patient's body or the display surface of the display unit 146 is hidden by the patient's body. Coupled with the fact that the display surface has a larger area than the irradiated surface 72 of the electronic cassette 22, the photographer can surely view information such as a radiographic image displayed on the display unit 146. In addition, since the display surface of the display unit 146 has a larger area than the irradiated surface 72 of the electronic cassette 22, as described in the first embodiment, character information (RIS information display / correction screen) and radiation Images can be displayed simultaneously, and a plurality of radiation images can be displayed simultaneously.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment and 2nd Embodiment, and description is abbreviate | omitted.
