Description

  The present invention relates to a radiographic image capturing system using a radiographic image detection apparatus, a portable information terminal apparatus, and a control apparatus, and a control apparatus therefor.

  In the field of medical diagnosis, a CR (Computed Radiography) system capable of handling radiographic images as digital data has been put into practical use. This CR system includes a reading device that reads radiation image data by scanning a phosphor plate built in a CR cassette with excitation light, and a control device (also called a console) that acquires the radiation image data read by the reading device. ) And are connected. Then, by reading the CR cassette irradiated with radiation in the radiography room with the reading device, and transmitting and displaying the obtained radiation image data to the control device, the radiographer has obtained the optimal radiation image data. Can be confirmed.

  Also, in order to support use in a medical institution or the like having a plurality of radiography rooms, introduction of a large-scale CR system in which a plurality of reading devices and a plurality of control devices are connected via a network has been proposed (Patent Literature). 1). In the large-scale CR system as described in Patent Document 1, there are a plurality of patients to be imaged at a time, and there are also a plurality of radiographers who perform imaging operations. There is. Accordingly, instruction information called imaging order information including patient information (patient name, age, etc.) and imaging information (imaging date, imaging region, imaging direction, etc.) is generated in advance, and the imaging order information and CR A method is adopted in which a cassette ID (identification information) for identifying a cassette is registered in association with each other. Thus, by associating one imaging order information with one CR cassette, the radiation image data obtained by reading the CR cassette with the reader is associated with the imaging order information based on the cassette ID of the CR cassette. Therefore, it is possible to prevent the radiation image data from being mixed up.

  By the way, in recent years, in order to enable radiography even for patients who are difficult to move to the radiography room due to serious reasons, mobile radiation irradiation devices for round visits have been realized. There has been provided a method for smoothly performing imaging work at a roundabout by carrying a personal digital assistant (PDA) together with the device and performing a roundabout (see, for example, Patent Document 2). In general, a round-trip imaging method using a PDA first transmits imaging order information scheduled to be taken at a round-trip destination from the control device to the PDA, and stores the imaging order information in the PDA. The radiation cassette for the patient and the number of CR cassettes taken are taken to the roundabout. At the roundabout, the imaging order information to be captured is displayed on the PDA, and the barcode (cassette ID) of the CR cassette is read by the barcode reader provided in the PDA, whereby the displayed imaging order information and cassette ID are displayed. Are associated with each other. Thereafter, the radiation irradiation device for round trips is operated based on the imaging order information to accumulate the radiation image in the CR cassette, the CR cassette is read by the reading device, and the obtained radiation image data is transmitted to the control device. Further, the correspondence relationship between the imaging order information stored in the PDA and the cassette ID is transmitted to the control apparatus, and the imaging order information and the radiation image data are associated with each other by the control apparatus. In this way, by carrying the PDA at the round-trip destination, after confirming the radiographing order information at the round-trip destination, the radiographing order information and the CR cassette can be associated with each other so that radiographing can be performed. Can be reliably prevented.

  On the other hand, instead of the above-mentioned CR cassette, an FPD (incorporating radiation detection elements two-dimensionally arranged on the substrate and outputting an electrical signal corresponding to the radiation dose irradiated to the radiation detection elements) A Flat Panel Detector device has been proposed as a radiation image detection device (see, for example, Patent Document 3). By using this FPD device, it is possible to obtain radiation image data directly without irradiating excitation light and reading a radiation image, and thus the system itself is simplified compared to the case of using a CR cassette. This makes it possible to perform shooting work smoothly. In addition, since a plurality of radiation image data can be stored in the storage unit built in the FPD device, a plurality of images can be continuously taken at a time, and the imaging efficiency is improved.

Since the FPD device has excellent convenience, it is assumed that the FPD device will be used in the future in place of the CR cassette. In particular, in round-trip photography, in which multiple shots are generally taken in a single round, the use of an FPD device eliminates the need to carry CR cassettes for the number of shots taken at the round-trip destination, making imaging work very easy It becomes.

  However, in the round trip imaging using the PDA as described above, if the FPD device is used instead of the CR cassette, there is a possibility that the imaging order information and the radiation image data are erroneously associated with each other. There arises a problem that the diagnosis proceeds without noticing the date.

  For example, in a single round-trip imaging, an imaging procedure in the case of taking a plurality of images using one FPD device first stores in the PDA a plurality of imaging order information that is scheduled to be acquired and stored in the PDA. A plurality of imaging order information is associated with one FPD device. Then, imaging is executed in ascending order of the order numbers included in the imaging order information, and radiation image data for a plurality of imagings are stored in one FPD device. Then, a plurality of pieces of radiation image data stored in the FPD device and association information between the imaging order information stored in the PDA and the FPD device are transmitted to the control device. Thereafter, the control device associates the imaging order information with the radiation image data based on the order number and the imaging order.

  However, for example, if the order of performing radiographic imaging is changed due to the convenience of a patient or a doctor, the control apparatus erroneously associates radiographic image data with imaging order information. At this time, if the plurality of pieces of radiation image data are, for example, pieces of radiation image data of a plurality of patients having the same (or similar) imaging site, the pieces of radiation image data cannot be distinguished from each other, resulting in incorrect association. It is difficult to notice. For this reason, radiographic image data and imaging order information cannot be accurately associated with each other, which may lead to a serious medical error.

  Therefore, the present invention has been made in view of the above-described problems, and even when an FPD device is used as a radiation image detection device, imaging order information and radiation image data can be accurately associated with each other. An object of the present invention is to provide a radiographic image capturing system and a control device therefor.

  In order to achieve the above object, a radiographic imaging system of the present invention includes a control device that stores a plurality of radiographing order information related to radiography, and at least two or more radiographing order information selected from the plurality of radiographing order information. A radiographic imaging system comprising: a portable information terminal device that stores data; and a radiographic image detection device that is capable of generating and storing radiographic image data corresponding to the two or more radiographing order information. In order to select the two or more pieces of photographing order information, photographing order information selecting means for selecting at least one piece of photographing order information from a plurality of pieces of photographing order information stored in the control device, and the photographing order information One shooting order information selected by the selection means and another shooting order information different from the one shooting order information have a predetermined relationship. And having a discriminating means for discriminating whether or not having.

  In order to achieve the above object, a control device of the present invention is a control device that is communicably connected to a portable information terminal device that stores at least two or more pieces of shooting order information selected from a plurality of pieces of shooting order information. And selecting at least one shooting order information from the plurality of shooting order information stored in the storage unit when selecting the storage unit storing the plurality of shooting order information and the two or more shooting order information. Whether or not there is a predetermined relationship between the imaging order information selection means to be performed, one imaging order information selected by the imaging order information selection means, and other imaging order information different from the one imaging order information Discriminating means for discriminating, one photographic order information selected by the photographic order information selecting means, and another categorized as having a predetermined relationship by the discriminating means A transmission unit that transmits at least one radiographing order information selected from among the shadow order information to the portable information terminal apparatus, characterized by having a.

  According to the present invention, since the operator can distinguish (distinguish) each of the radiographic image data, even if the radiographic image data and the imaging order information are associated with each other by mistake, it is possible to easily determine the error. Is possible. Therefore, the radiographic image data and the imaging order information can be associated with each other accurately, so that the radiographic image data can be prevented from being mistaken, and the occurrence of a medical error can be suppressed.

  Further, the operator selects one CR cassette 9 to be used for shooting from among the CR cassettes 9 for the number of shots, reads the barcode of the CR cassette 9 with the reading unit 107, and sets the cassette ID of the CR cassette 9. get. Then, the cassette ID and the imaging order information displayed on the display unit 105 are associated with each other and stored in the storage unit 21 as correspondence information.

  Then, after confirming the imaging region and imaging direction of the patient based on the imaging order information displayed on the display unit 105, the operator installs the selected one CR cassette 9 at a location corresponding to the imaging region. Thereafter, the radiation irradiation apparatus 4 for round trips is operated to emit radiation, and the CR cassette 9 accumulates the radiation dose corresponding to the radiation image.

  When the above shooting is repeated and shooting corresponding to all the shooting order information stored in the storage unit 21 is completed, the operator inserts the CR cassettes 9 for the number of shots into the reading device 3, and for each CR cassette 9. Radiation image data and cassette ID are acquired. Then, the radiographic image data and the cassette ID are associated with each other and transmitted to the console 7. Further, the PDA 10a is mounted on the cradle 10b, and the correspondence information between the imaging order information and the cassette ID stored in the storage unit 21 of the PDA 10a is transmitted to the console 7.

Then, the console 7 associates the radiographic image data transmitted from the CR cassette 9 with the imaging order information transmitted from the PDA 10a based on the cassette ID of the CR cassette 9. At this time, since the correspondence between the radiation image data and the CR cassette and the correspondence between the imaging order information and the CR cassette are respectively transmitted to the console 7, the radiation image data and the imaging order information are accurately based on these. Can be associated.
<For FPD mode>
When receiving the FPD mode input from the operation input unit 18 (the FPD mode in step S3), the control unit 14 displays an input screen 171 (see FIG. 7) for inputting shooting order information corresponding to the current shooting. 17 (step S4).

  The operator operates the input operation unit 18 while confirming the first shooting order information display field 171a of the display unit 17, and clicks an item on which one shooting order information corresponding to the current shooting is displayed. Here, it is assumed that the shooting order information item whose “shooting order ID” P1 is “001” is clicked.

  Upon receiving an input from the input operation unit 18, the control unit 14 selects one imaging order information whose “imaging order ID” P <b> 1 is “001” from the imaging order information list stored in the storage unit 21. (Step S5: photographing order information selection means). Then, it is determined whether or not the selected one imaging order information and other imaging order information stored in the storage unit 21 have a predetermined relationship (step S6; determination means). Specifically, whether or not the “patient ID” P2 included in the selected one imaging order information is the same as the “patient ID” P2 included in the other imaging order information, that is, other It is determined whether or not the “patient ID” P2 of the imaging order information is “100085”. Then, the imaging order information whose “patient ID” P2 is “100085” among the other imaging order information is displayed on the display unit 17 as the discrimination result screen 172 (step S7).

  FIG. 8 is a diagram showing an example in which a discrimination result screen 172 showing the discrimination result is displayed on the display unit 17. As shown in FIG. 8, a selected shooting order information display field 172a for displaying the one shooting order information selected in step S5 is provided at the top of the discrimination result screen 172. In the center of the discrimination result screen 172, a second imaging order information display field 172b for displaying imaging order information having the same “patient ID” P2 as the selected imaging order information is provided. In addition, a “decision button” 172c and a “return button” 172d are provided at the bottom of the determination result screen 172. Note that, as will be described later, only the imaging order information displayed in the second imaging order information display field 172b is permitted for additional selection, and this corresponds to the permission means in the present invention.

  The operator operates the input operation unit 18 while confirming the second imaging order information display field 172b of the display unit 17, and desires from the imaging order information displayed in the second imaging order information display field 172b. Click the shooting order information item. Usually, in one imaging flow, it is more efficient to select a plurality of radiographing order information and perform a plurality of radiographic imaging collectively, and therefore, here, the “imaging order ID” P1 is “002” and “003”. It is assumed that the photographing order information having “” is clicked together. When the input of the imaging order information is completed, the “OK” button 172c is clicked.

  Upon receiving an input from the input operation unit 18, the control unit 14 of the console 7 has the “patient ID” P2 of “100085”, that is, the “imaging order ID” P1 of “002” and “003”. Information is additionally selected (step S8). Then, after the shooting order information selected in step S5 and the shooting order information selected in step S8 are associated (step S9), the shooting mode information set in step 3 and the shooting order information selected in step 9 are selected. The imaging order information is transmitted to the PDA 10a (step S12), and the process ends.

  Thereafter, the operator removes the PDA 10a from the cradle 10b, carries the round-trip radiation irradiating device 4, the one FPD cassette 6 and the PDA 10a to the hospital room 100 where the patient scheduled to be photographed, and executes radiation imaging. Specifically, the operator first operates the input operation unit 104 of the PDA 10a, and associates the three imaging order information transmitted from the console 7 and stored in the storage unit 21 with the cassette ID of the FPD cassette 6, This is stored in the storage unit 21 as correspondence information. Here, as a method of obtaining the cassette ID of the FPD cassette 6 when performing this association, for example, the cassette ID pasted on the surface of the FPD cassette 6 may be input by the input operation unit 104. The cassette ID may be received from the FPD cassette 6 by performing infrared communication.

  Then, the operator operates the input operation unit 104 of the PDA 10 a and causes the display unit 105 to display one shooting order information to be shot from among the three shooting order information stored in the storage unit 103. Normally, since the shooting order information “shooting order ID” P1 is shot in ascending order, first, shooting order information with the youngest “shooting order ID” P1 is displayed.

  Then, after confirming the imaging region and imaging direction of the patient based on the imaging order information displayed on the display unit 105, the operator installs the FPD cassette 6 at a location corresponding to the imaging region. Then, the radiation irradiation apparatus 4 for round trips is operated to emit radiation, and radiation image data is generated by the FPD cassette 6 and stored in the image storage unit 66.

  When the above-described shooting is repeated and shooting corresponding to the three shooting order information is completed, the operator presses a transmission button (not shown) provided on the FPD cassette 6 to store 3 stored in the image storage unit 66. Radiographic image data for imaging is transmitted to the console 7 via the base station 5 in the order in which imaging was performed (imaging order). At this time, the radiographic image data is transmitted with the cassette ID of the FPD cassette 6 attached thereto. Thereafter, the PDA 10a is mounted on the cradle 10b, and the correspondence information between the imaging order information and the cassette ID stored in the storage unit 21 of the PDA 10a is transmitted to the console 7.

  In the console 7, the radiographic image data for three radiographs transmitted from the FPD cassette 6 and the three radiographing order information transmitted from the PDA 10a are associated with each other. This association is performed based on the transmission order (imaging order) in which the radiation image data is transmitted from the FPD cassette 6 and the youngest order of the “imaging order ID” P1. That is, as described above, in normal imaging, imaging is performed in ascending order of “imaging order ID” P1, and radiation image data is stored in the image storage unit 66 of the FPD cassette 9 in this imaging order. Therefore, if the association is performed on the console 7 based on the imaging order (transmission order) of the radiation image data and the descending order of the “imaging order ID” P1, these can be automatically and accurately associated.

  However, for example, if the imaging order ID “P1” is not photographed in the order of younger shooting due to the convenience of the operator or the patient, the imaging order is different from the youngest order of the “imaging order ID” P1. If the radiographic image data and the imaging order information are associated with each other by this method, they are erroneously associated. At this time, if the three imaging order information includes imaging order information having the same imaging part (or similar), the radiographic image data acquired and generated based on the imaging order information is also the same (or Similar). In this case, since the operator cannot distinguish the radiation image data from each other, it is difficult to notice an incorrect association between the radiation image data and the imaging order information.

  Therefore, in the FPD mode, only the imaging order information of the same patient can be transmitted as the imaging order information to be transmitted to the PDA 10a according to the procedure described in step 6 to step 8 above. Usually, when imaging the same patient multiple times, radiation generated in response to the imaging order information of the same patient is unlikely to capture the same site or a similar site in a single imaging flow. If it is image data, the operator can easily distinguish it. For this reason, the operator can display the radiation image data and the imaging order information on the display unit 17 of the console 7, and if the association is incorrect, the operator can operate the input operation unit 18 to correct the association. It becomes possible.

  Thus, in the FPD mode of the present embodiment, a plurality of radiographs are generated using one FPD cassette 6 to generate radiographic image data for a plurality of radiographs. Then, when selecting a plurality of radiographing order information respectively corresponding to the radiographic image data for a plurality of radiographs, when one radiographing order information is selected, the “patient ID” P2 of the one radiographing order information and another Whether or not the “patient ID” P2 of the imaging order information is the same is determined, and only other imaging order information that is the same can be additionally selected. As described above, in general, when the same patient is imaged a plurality of times, it is unlikely that the same region or a similar region is imaged twice during one imaging flow.

  For this reason, even when the same patient is imaged a plurality of times by one FPD cassette 6 and the generated radiographic image data for a plurality of radiographs are simultaneously stored, the radiographic image data for the plurality of radiographs is displayed on the console 7 Furthermore, the operator can distinguish which radiographic image data corresponds to which radiographing order information. Therefore, even if the radiographic image data and the radiographing order information are erroneously associated with each other, the operator can easily notice the erroneous association, and this can be accurately associated. Therefore, it is possible to prevent the radiation image data from being mistaken and to suppress the occurrence of a medical error.

  Further, based on the selected one shooting order information, the control unit 14 of the console 7 determines which shooting order information can be additionally selected. Therefore, when the imaging order information is additionally selected, it is not necessary for the doctor himself to make a judgment, so that work efficiency is improved.

  In addition, since the discrimination result screen 172 showing the discrimination result is displayed on the display unit 17 and the imaging order information for which additional selection is permitted is input based on the discrimination result, the imaging order that can be additionally selected. Information can be determined at a glance, and it is possible to reduce omission of selection of imaging order information by an operator.

  In addition, since the CR mode and the FPD mode can be selected, an optimal shooting mode can be selected according to the situation, and the efficiency of shooting work can be improved.

  In the above-described embodiment, the “patient ID” that is the same as the “patient ID” P2 of the selected one imaging order information as the imaging order information having a predetermined relationship with the selected one imaging order information. Although it is set as having P2, it is of course not limited to this. For example, it is set as imaging order information having “imaging site” P7 different from “imaging site” P7 included in one selected imaging order information, or at least one of “imaging site” P7 and “imaging direction” P8. May be set as imaging order information having “imaging region” P7 and “imaging direction” P8 different from each other.

  By setting in this way, even if a plurality of radiographic image data obtained by imaging different patients are simultaneously stored in one FPD cassette 6, the operator can identify which radiographic image data corresponds to which radiographing order information. It is possible. Therefore, radiation imaging can be performed across a plurality of patients in one imaging flow, and imaging efficiency is further improved. On the other hand, for example, when imaging L (left) and R (right) in the vertical direction (also referred to as CC) of a breast part, even if the “imaging direction” P8 differs between L and R, the radiographic image data can be distinguished. There is a risk that the radiographic image data will be mistaken. Therefore, when the radiographic image data cannot be distinguished like CC-L and CC-R of the breast part, the simultaneous selection is prohibited. As described above, having a predetermined relationship in the present invention can be set as appropriate according to each work mode as long as the operator can recognize the radiation image data.

  In the above description, when additional photographing order information is selected, the operator inputs from the input operation unit 18 and is selected. However, as described above, in one imaging flow, it is more efficient to select a plurality of imaging order information and perform a plurality of radiation imagings together. Order information may be automatically selected. This configuration eliminates the need for the doctor to select additional imaging order information by himself, thus improving work efficiency and automatically selecting all imaging order information that can be captured in one imaging flow. It is possible to prevent omission of selection of the imaging order information.

  Further, in one round-trip imaging, imaging is performed in either the CR mode or the FPD mode, but imaging may be performed by combining these modes. For example, first, the FPD mode is set on the console 7, and one piece of photographing order information and photographing order information having a predetermined relationship with the one piece of photographing order information are transmitted to the PDA 10a. Next, the CR mode is set, and all the desired imaging order information is transmitted to the PDA 10a out of the imaging order information excluding the imaging order information transmitted to the PDA 10a in the FPD mode. Then, after carrying the round irradiation radiation apparatus 4, one FPD cassette 6, the CR cassette 9 and the PDA 10a for the number of images taken in the CR mode to the hospital room 100, the PDA 10a performs imaging while switching between the CR mode and the FPD mode. .

  Thus, by combining the CR mode and the FPD mode, radiographing order information that makes it impossible to distinguish the radiographic image data when radiographed with the FPD cassette 6 can be imaged using the CR cassette 9. Therefore, since it is possible to further shoot in a single shooting flow while suppressing the number of cassettes carried (used) by the operator as much as possible, it is possible to perform shooting work more efficiently.

  In the above description, in associating the imaging order information with the radiographic image data at the console 7, the radiographic image data is transmitted from the FPD cassette 6 via the base station 5, and the radiographing order information is transmitted from the PDA 10a via the cradle 10b. These are configured to be transmitted to the console 7 separately. However, the present invention is not limited to this, for example, when imaging order information is transmitted from the PDA 10 a to the FPD cassette 6 and stored in the FPD cassette 6 before imaging, and radiation image data is transmitted from the FPD cassette 6 to the console 7. In addition, the imaging order information may be transmitted together.
