As a radiation conversion panel used in this radiographic imaging apparatus, a conventional radiation film in which a radiographic image is exposed and recorded, or radiation energy as a radiographic image is accumulated in a phosphor and irradiated with excitation light to generate a radiographic image. A stimulable phosphor panel that can be extracted as stimulated emission light is known. These radiation conversion panels supply a radiation film on which a radiation image is recorded to a developing device to perform development processing, or supply a stimulable phosphor panel to a reading device to perform reading processing so that a visible image can be obtained. A radiographic image is obtained.

  However, although not explicitly disclosed in Patent Document 1, whether or not the combination of patient information and image data is correct is determined by the photographer (radiologist) in the technique described in Patent Document 1. Has been made. For this reason, an error may occur in the combination of patient information and image information. That is, the photographer needs to select a film according to the inspection order, but there is a possibility that the wrong film is used due to the photographer's error. The photographer confirms the correct combination of the patient information and the image data by confirming the name of the photographed subject (patient) with the photographed subject, but the photographed person responds by mistake. Therefore, the possibility that the photographer mistakes the photographed person cannot be denied.

  In the imaging permission / inhibition determination step, it is preferable that the irradiation of the radiation is permitted when the actual specification of the conversion panel is equal to or more than the required specification. Thereby, even when the actual specification is not the same as the required specification and exceeds the required specification, irradiation of radiation is permitted. Therefore, even when the number of actual cassettes is small, it is possible to flexibly shoot while satisfying the required specifications.

The patient identification information reading means for reading, the designated patient identification information which is the patient identification information of the patient scheduled to take the radiographic image, and the patient identification information storage means of the patient who is actually to be imaged Second patient imaging which collates with the actual patient identification information which is the patient identification information read by the patient identification information reading unit by the identifying unit, and determines whether the radiographic image is captured by the identifying unit according to the collation result It is preferable to have a permission / rejection determination step. Thereby, since designated patient identification information and real patient identification information are collated by an identification means, a patient's mistake can be prevented more reliably.

  In the radiographic imaging method, a plurality of imaging requests are input to the radiographic imaging system, and in the second imaging permission determination step corresponding to the earliest imaging request, the designated patient identification information and When the real patient identification information does not match, it is preferable to execute the second imaging permission / rejection determination step for the remaining imaging requests. As a result, even if the order of photographing is wrong, photographing can be advanced promptly by not photographing in order.

  Further, the patient identification information reading unit and the conversion panel identification information reading unit are provided near an exit of a place where the radiographic image is taken, and the radiography of the radiographic image is finished in the patient identification information reading unit. An imaging end patient identification information reading / notifying step of reading patient identification information of a patient and notifying the identification means, and conversion panel identification information of a conversion panel that has completed imaging of the radiation image in the conversion panel identification information reading means. An imaging end conversion panel identification information reading / notification step for reading and notifying the identification means; and in the identification means, the patient identification information of the patient who has completed imaging of the radiation image and the conversion panel having completed imaging of the radiographic image. Until the conversion panel identification information is received, the next radiographic image is temporarily prohibited. A step, it is preferable to have a.

  As a result, the next imaging cannot be performed until the patient who has completed imaging is withdrawn from the place where the radiographic image is being taken and the conversion panel that has been taken is taken out of the place. Therefore, it is possible to prevent the patient and the conversion panel from taking different images before and after.

2. Operation of the present embodiment The RIS 10 of the present embodiment is basically configured as described above. Next, the operation will be described.

  In order to facilitate understanding of the present invention, the operation of the RIS 10 is as follows. The radiographic imaging system 20 is not in the operating room 31 as shown in FIG. 2 but in the radiographic room installed exclusively for radiographic imaging. An example in which is installed will be described.

  In step S <b> 1 of FIG. 6, the imaging request input terminal 12 receives an imaging request from a doctor 75 or a radiologist. In this imaging request, the date and time of imaging and imaging conditions {imaging site, angle and number, tube voltage for irradiating radiation X, tube current, irradiation time, and size and sensitivity of cassette 24 (radiation detector 40) (cassette 24 required specifications) etc.} is designated. However, in the cassette DB 17 of the RIS server 14, if input items such as the imaging part and the specification of the cassette 24 are stored in association with each other, it is sufficient to specify fewer items. The imaging request is associated with the patient ID of the patient 71 who performs imaging. When a doctor 75 or a radiographer inputs an imaging request, the reservation status of the radiographic imaging system 20 is confirmed in advance using the schedule DB 18 of the RIS server 14.

  In step S <b> 2, the imaging request input terminal 12 notifies the RIS server 14 of the contents of the received imaging request (including the required specifications of the cassette 24) and the patient ID.

  In step S <b> 3, the RIS server 14 records the details of the imaging request (date and time of imaging, imaging conditions) notified from the imaging request input terminal 12 and the patient ID in the schedule DB 18. As described above, in the cassette DB 17, when input items are associated and stored, the associated items are also recorded in the schedule DB 18.

  The contents recorded in the schedule DB 18 can be confirmed at any time from the console 30 of each radiographic image capturing system 20. In other words, if the console 30 of the imaging system 20 is accessing the schedule DB 18 of the RIS server 14 when the processing of step S3 is performed, the content of the imaging request (the cassette 24) is sent from the RIS server 14 to the console 30. The combination of patient specifications and patient ID is notified (downloaded) (step S4). When urgent shooting is required, the RIS server 14 can actively notify the console 30 of the contents of the shooting request.

  The radiologist takes a radiographic image based on the schedule notified from the RIS server 14. This schedule is displayed on the monitor of the console 30. Before the first radiographic image capture is started, the radiologist selects the cassette 24 to be used for the first radiographing based on the display on the console 30, that is, the required specifications of the cassette 24. Each cassette 24 is arranged outside the radiographing mode in a power saving mode (a mode in which the cassette control unit 46 can receive a specific external signal, but no power is supplied to the radiation detection unit 40 and radiation detection is not possible). When the radiographer brings the selected cassette 24 into the imaging room, the cassette ID of the cassette 24 is read by the cassette ID reader 27 (step S5). In order for the cassette ID reader 27 to read the cassette ID from the cassette 24, for example, until there is a response from the cassette 24, a predetermined radio wave intensity from the cassette ID reader 27 (for example, only within a radius of 1 m from the cassette ID reader 27). It is possible to continue transmitting the cassette ID request signal at a radio wave intensity capable of establishing communication). Upon receipt of the cassette ID request signal from the cassette ID reader 27, the cassette 24 (cassette control unit 46) is triggered by this to supply power from the power saving mode to the normal mode (radiation detection unit 40 is supplied with power). Mode).

  In step S <b> 6, the cassette ID reader 27 notifies the console 30 of the read cassette ID, and the console 30 notifies the RIS server 14 of the received cassette ID.

  Next, in step S <b> 7, the RIS server 14 reads the specification (actual specification) of the cassette 24 associated with the cassette ID notified from the console 30 from the cassette DB 17. In step S8, the RIS server 14 notifies the console 30 of this actual specification.

  Next, in step S9, the imaging condition management unit 98 of the console 30 sets the specification (required specification) of the cassette 24 notified from the RIS server 14 as the cassette 24 scheduled to be used for radiographic imaging, and the actual imaging room. Is compared with the actual specification of the cassette 24 corresponding to the cassette ID read by the cassette ID reader 27 from the cassette 24 arranged in the step S10. In step S10, whether the actual specification is appropriate, that is, the actual specification is required. It is determined whether or not the specification is exceeded.

  When the actual specification of the cassette 24 is less than the required specification, the console 30 does not permit the irradiation of the radiation X by the imaging device 22 in step S11. That is, a signal for prohibiting radiation X irradiation from the radiation source 74 is transmitted from the imaging condition management unit 98 of the console 30 to the radiation source control unit 78 of the imaging apparatus 22. In this case, the fact is displayed on the monitor of the console 30, and the process returns to step S5. If the actual specification is greater than or equal to the required specification, the process proceeds to step S12.

  Next, based on the display on the console 30, the radiologist specifies the patient who is the subject of the first imaging, and calls the patient who is the imaging subject into the imaging room. When the patient to be imaged enters the imaging room, the patient ID reader 28 installed near the entrance of the imaging room reads the patient ID of the patient from the patient tag 19 of the patient to be imaged, and reads the read patient ID. The console 30 is notified (step S12).

  Next, in step S13, the patient information management unit 102 of the console control unit 97 of the console 30 and the patient ID (designated patient ID) notified from the RIS server 14 as the patient ID of the patient to be radiographed, and actually The patient ID (actual patient ID) read by the patient ID reader 28 from the patient tag 19 of the patient who has entered the imaging room is collated.

  If the designated patient ID and the actual patient ID do not match, the console 30 does not allow the radiation X to be emitted by the imaging device 22 in step S14. That is, the patient information management unit 102 of the console 30 transmits a signal prohibiting irradiation of the radiation X by the radiation source 74 to the radiation source control unit 78 of the imaging apparatus 22. In this case, the fact is displayed on the console 30, and the process returns to step S12. When the designated patient ID and the real patient ID match, the console 30 permits irradiation of the radiation X by the imaging device 22.

  Note that the order of steps S5 to S11 and steps S12 to S14 may be reversed, or may be performed in parallel.

  Even when the designated patient ID and the actual patient ID do not match, if the combination of the actual patient ID and the actual cassette ID is correct, that is, the imaging order is wrong, the content of the imaging request itself is satisfied. In this case, a configuration in which the console 30 permits irradiation of the radiation X by the imaging device 22 is also possible.

  In step S15, when the radiographic image capturing is completed, in step S16, the radiographic image information acquired by the cassette 24 is transmitted to the console 30, and the console 30 sends the received radiographic image information and the corresponding patient ID to the RIS server. 14 to send. Next, in step S17, the RIS server 14 stores the received radiation image information in the patient DB 16 in association with the patient ID. The radiation image information stored in the patient DB can be viewed from the imaging request input terminal 12.

  In step S15, when the radiographic image capturing is completed, in step S18, the console 30 monitors whether the patient who has completed the imaging has left the imaging room. If the patient who has finished imaging has not left the imaging room, the console 30 does not permit the next imaging in step S19. For example, a signal for prohibiting irradiation of the radiation X from the radiation source 74 is transmitted from the console 30 to the imaging apparatus 22. Alternatively, a warning message is displayed on the monitor of the console 30 or the display device 26 to promptly leave the patient. If the console 30 determines in step S18 that the patient who has finished imaging has left the imaging room, the process proceeds to step S20.

  For example, when the patient ID reader 28 reads a specific patient ID for the first time, it is determined that the patient is entering the room, and when the same patient ID is read twice, it is determined that the patient is leaving the room. be able to. Alternatively, it is also possible to provide two reading sensors in the patient ID reader 28 and determine the patient's entrance / exit based on the order in which the two reading sensors read the patient ID. In this case, for example, when the reading sensor on the outer side reads the patient ID earlier than the reading sensor on the inner side, it is determined that the patient enters the room, and the reading sensor on the inner side reads the patient ID earlier than the reading sensor on the outer side. If it is, leave the room.

  In subsequent step S20, the console 30 monitors whether or not the cassette 24 that has finished photographing has been taken out of the photographing room. If the cassette 24 that has finished photographing has not yet been taken out of the photographing room, in step S21, the console 30 does not permit the next photographing by the same method as in step S19. In step S20, when the console 30 determines that the cassette 24 that has finished shooting has been taken out of the shooting room, the process proceeds to step S22, and the console 30 permits the next shooting. The method by which the console 30 determines whether or not the cassette 24 has been taken out of the imaging room is the same as the method in step S18.

3. Effects of the Present Embodiment As described above, in the present embodiment, the required specifications of the cassette 24 and the actual specifications are compared, and based on the comparison result, whether or not radiographic imaging is permitted is determined. For this reason, the difference of the cassette 24 can be prevented more reliably.

  On the other hand, when the console 30 determines that the radiographic image capturing is not permitted based on the comparison result of the specifications of the cassette 24 and the collation result of the patient ID, the console 30 prohibits the radiation source 74 from irradiating the radiation. As a result, when the console 30 determines not to allow radiographic imaging, the irradiation with the radiation X can be automatically prohibited, so that safety can be improved.

  When the actual specification of the cassette 24 is equal to or greater than the required specification, the console 30 permits irradiation of the radiation X. Thereby, irradiation of the radiation X is permitted even when the actual specification is not the same as the required specification and exceeds the required specification. Therefore, even when there are few types of actual cassettes 24, it is possible to perform flexible shooting while satisfying the required specifications.

  The cassette 24 shifts from the power saving mode to the normal mode when receiving the cassette ID request signal from the cassette ID reader 27. Thereby, it is possible to save power consumption when shooting is not performed.

  The designated patient ID input to the console 30 as the patient ID of the patient 71 scheduled to capture a radiographic image and the actual patient ID notified to the console 30 as the patient ID of the patient 71 that is actually the imaging target are the console. 30 is collated. For this reason, it is possible to prevent the patient 71 from being mixed more reliably.

  A plurality of imaging requests are notified to the radiographic imaging system 20, and a patient ID (designated patient ID) downloaded from the RIS server 14 to the console 30 in response to the earliest imaging request, and a patient ID reader When the patient ID (real patient ID) notified from the console 28 to the console 30 does not match, the remaining imaging request is notified from the RIS server 14 to the console 30 and the patient ID reader 28. When the two patient IDs match with respect to the remaining imaging requests, the console 30 determines the specification of the cassette 24 and determines whether the imaging is permitted or not in response to the remaining imaging requests. . As a result, even if the order of photographing is wrong, photographing can be advanced promptly by not photographing in order.

  Further, the console 30 is instructed until the patient ID reader 28 and the cassette ID reader 27 provided in the vicinity of the entrance / exit of the radiographing room notify the exit of the patient 71 who has completed radiographing and the removal of the cassette 24 from which radiography has been completed. The next radiation image is temporarily prohibited. As a result, it is possible to prevent the patient 71 and the cassette 24 from taking and returning before and after photographing.

4). Modifications It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted based on the contents described in this specification. For example, the following configurations (1) to (8) can be adopted.

(1) Radiation imaging system 20
In the said embodiment, although the imaging | photography system 20 was arrange | positioned in the operating room 31 or the imaging | photography room | chamber interior, it is not restricted to this. For example, the imaging system 20 can be made movable rather than mounted, and used when visiting each hospital room.

  In the above embodiment, the imaging system 20 is included in the RIS 10, but the imaging system 20 may be used alone. In this case, the specification of the cassette 24 and the patient ID can be directly input to the console 30 itself.

  Moreover, in the said embodiment, although both the specification of the cassette 24 and patient ID were used, the structure which uses only one is also possible.

(2) Radiation conversion panel (radiation detector 40)
In the above embodiment, the radiation detector 40 accommodated in the radiation detection cassette 24 converts the dose of the incident radiation X directly into an electrical signal by the photoelectric conversion layer 51. A radiation detector configured to once convert the radiation X into visible light with a scintillator and then convert the visible light into an electrical signal using a solid-state detection element such as amorphous silicon (a-Si) may be used ( (See Japanese Patent No. 3494683).

  Also, radiation image information can be obtained using a light conversion type radiation detector. In this light conversion type radiation detector, when radiation is incident on each solid detection element arranged in a matrix, an electrostatic latent image corresponding to the dose is accumulated and recorded in the solid detection element. When reading the electrostatic latent image, the radiation detector is irradiated with reading light, and the value of the generated current is acquired as radiation image information. The radiation detector can erase and reuse the radiation image information that is the remaining electrostatic latent image by irradiating the radiation detector with erasing light (see Japanese Patent Application Laid-Open No. 2000-105297). .

(3) Conversion Panel Specifications In the above embodiment, the sensitivity and size are used as the specifications of the cassette 24 (radiation detector 40), but are not limited thereto. For example, a resolution, the number of images that can be captured, and a radiation detection method may be used.

(4) Conversion panel database (cassette DB17)
In the above embodiment, the cassette DB 17 records the cassette ID of the cassette 24, the specification, and the contents of the imaging request that can be dealt with. A database in which the contents of the imaging request and the specifications of the cassette 24 are recorded in association with each other can be provided separately.

(5) Conversion Panel Identification Information Reading Unit In the above embodiment, the cassette ID reader 27 is provided in the vicinity of the entrance / exit of the photographing room. However, the present invention is not limited to this as long as the cassette ID can be read. For example, it can also be provided near the operating table. It can also be built in the console 30 or the photographing device 22. Further, the reading of the cassette ID by the cassette ID reader 27 is not necessarily limited to the non-contact method, and may be a contact method.

(6) Patient identification information (patient ID)
In the above embodiment, when the patient ID (designated patient ID) notified from the RIS server 14 to the radiographic imaging system 20 matches the patient ID (real patient ID) read from the patient ID reader 28, the radiation The photographing of the image is permitted, but it is not always necessary to match the two patient IDs if they are associated with each other. For example, for security reasons, a configuration in which a number included in one patient ID and a number included in the other patient ID are intentionally different according to a predetermined rule is also possible.

(7) Patient identification information storage means (patient tag 19) and patient identification information reading means (patient ID reader 28)
In the said embodiment, although the patient tag 19 was used as what memorize | stores patient ID, if it can memorize | store patient ID, it will not be restricted to this. For example, a bar code printed band that can be wrapped around the patient's wrist may be used. In this case, the patient ID reader 28 can use a bar code reader.

  In the above-described embodiment, the patient ID reader 28 is disposed near the entrance / exit of the operating room 31 or the imaging room, but the present invention is not limited to this. For example, it may be provided inside the operating table 73 or the cassette 24.

(8) Others In the above embodiment (FIG. 6), the required specification of the cassette 24 is input at the imaging request input terminal 12, but it can also be performed at the RIS server 14 as shown in FIG. That is, in the cassette database of the RIS server 14, the contents of the imaging request (imaging site, etc.) and the specifications (size, sensitivity, etc.) of the cassette 24 are recorded in advance and the requested specifications of the cassette 24 are recorded in the imaging request input terminal 12. The RIS server 14 can also determine the required specifications of the cassette 24 according to the contents of the imaging request (step S24 in FIG. 8).

  In the above embodiment (FIG. 6), the process of comparing the specifications of the cassette 24 and determining the suitability (steps S9 and S10) is performed by the radiographic imaging system 20, but as shown in FIG. It is also possible to do this. That is, after the RIS server 14 notifies the imaging system 20 of the contents of the imaging request in step S25 in FIG. 8, the cassette ID reader 27 reads the cassette ID (step S26), and the read cassette ID is read from the imaging system 20 to the RIS. The server 14 is notified (step S27).

  Then, the RIS server 14 reads the specification of the cassette 24 associated with the cassette ID notified from the imaging system 20 as the actual specification from the cassette DB 17 (step S28). Next, the required specification of the cassette 24 confirmed in step S24 is compared with the actual specification confirmed in step S28, and the suitability of the actual specification is determined (step S29). Next, the RIS server 14 notifies the imaging system 20 of this determination result (step S30).

  The imaging system 20 that has received the determination result notification from the RIS server 14 confirms the content of the determination result (appropriateness of the actual specification) (step S31). If the actual specification does not satisfy the required specification, the imaging system 20 does not permit imaging of a radiographic image in the same manner as described above (step S32). If the actual specification is greater than or equal to the required specification, the imaging system 20 proceeds to step S33.

  Since the process of step S33-S38 is the same as that of step S12-S17 of FIG. 7, detailed description is abbreviate | omitted. In FIG. 9, steps corresponding to steps S18 to S22 of FIG. 7 are not described, but steps corresponding to these steps may be added.

  Alternatively, by making the cassette DB 17 of the RIS server 14 directly accessible from the imaging system 20 or by providing the imaging system 20 with a database similar to the cassette DB 17, the actual specifications of the cassette 24 are confirmed by the imaging system 20. A configuration in which the real cassette ID is not notified to the RIS server 14 (a configuration in which step S6 in FIG. 6 is omitted and steps S7 and S8 are performed in the imaging system 20) is also possible.

  In the above embodiment (FIGS. 6 and 7), the process (steps S12 to S14) related to the verification of the patient ID is performed after the process related to the determination of the specification of the cassette 24 (steps S5 to S11). As shown in FIG. 11, the process (steps S <b> 45 to S <b> 47) related to patient ID collation can be performed prior to the process related to determination of the specification of the cassette 24 (steps S <b> 48 to S <b> 54). Alternatively, both processes can be performed in parallel.

  In the above embodiment, the console 30 is arranged in the operating room 31 or in the imaging room. However, the imaging apparatus 22, the radiation detection cassette 24, the display apparatus 26, the cassette ID reader 27, and the patient ID reader 28 are wirelessly communicated. As long as signals can be transmitted and received, the console 30 may be installed outside the operating room 31 or the imaging room.

  As shown in FIG. 12, it is more preferable to configure a radiation detection cassette 500 (hereinafter referred to as “cassette 500”).

  That is, the guide line 504 serving as a reference for the imaging region and the imaging position is formed on the cassette 500 on the radiation irradiation surface side of the casing 502. By using this guide line 504 to position the subject (patient 71) with respect to the cassette 500 and setting the radiation X irradiation range, radiographic image information can be recorded in an appropriate imaging region.

  A display unit 506 that displays various types of information related to the cassette 500 is disposed outside the imaging region of the cassette 500. In the display unit 506, the ID information of the patient 71 recorded in the cassette 500, the number of uses of the cassette 500, the cumulative exposure dose, the state of charge (remaining capacity) of the battery 44 built in the cassette 500, radiation image information Imaging conditions, a positioning image of the patient 71 with respect to the cassette 500, and the like are displayed. In this case, for example, the engineer confirms the patient 71 according to the ID information displayed on the display unit 506, confirms in advance that the cassette 500 is in a usable state, and based on the displayed positioning image. A desired imaging region of the patient 71 can be positioned on the cassette 500, and optimal radiographic image information can be imaged.

  Further, by forming the handle portion 508 in the cassette 500, it becomes easy to handle and carry the cassette 500.

  An AC adapter input terminal 510, a USB (Universal Serial Bus) terminal 512, and a card slot 516 for loading a memory card 514 are preferably provided on the side of the cassette 500.

  The input terminal 510 is connected to an AC adapter when the charging function of the battery 44 built in the cassette 500 is deteriorated or when sufficient time for charging the battery 44 cannot be secured. By supplying this, the cassette 500 can be immediately used.

  The USB terminal 512 or the card slot 516 can be used when the cassette 500 cannot exchange information with an external device such as the console 30 by wireless communication. In other words, by connecting a cable to the USB terminal 512, information can be transmitted / received to / from an external device by wired communication. In addition, information can be transmitted and received by loading a memory card 514 into the card slot 516, recording necessary information on the memory card 514, and then removing the memory card 514 and loading it into an external device.

  As shown in FIG. 13, it is preferable to place a cradle 518 that is loaded with a cassette 24 and charges a built-in battery 44 at a required location in the operating room 31 or hospital. In this case, the cradle 518 uses the wireless communication function or the wired communication function of the cradle 518 as well as the charging of the battery 44, and information necessary for the RIS server 14, the HIS server 15, the console 30, and other external devices. May be transmitted / received. The information to be transmitted and received can include radiation image information recorded in the cassette 24 loaded in the cradle 518.

  In addition, a display unit 520 is provided in the cradle 518 so that necessary information including the charged state of the loaded cassette 24 and the radiation image information acquired from the cassette 24 is displayed on the display unit 520. May be.

  Further, a plurality of cradle 518 is connected to a network, and the charging state of the cassette 24 loaded in each cradle 518 is collected via the network so that the location of the cassette 24 in a usable charging state can be confirmed. You can also
