Description

  The present invention relates to a medical image photographing system.

  Images taken using radiation are widely used as medical images for diagnosis, and in recent years, digitization of medical images has been realized. For example, a CR (Computed Radiography) apparatus accumulates radiation transmitted through a subject in a stimulable phosphor sheet on which a stimulable phosphor layer is formed, and then scans the stimulable phosphor sheet with laser light. Thus, the medical image data is obtained by photoelectrically converting the photostimulated light emitted from the photostimulable phosphor sheet.

  This medical imaging system using photostimulable phosphors can be broadly divided into a built-in photostimulable phosphor sheet and a dedicated type that performs both imaging and image reading and a photostimulable phosphor sheet. It is classified into a cassette type using a portable cassette.

  A cassette type medical image photographing system includes a control device and a medical image reading device. The medical image reading device reads medical image data and cassette identification information from a cassette and transmits them to a control device. The control device stores the imaging order information including the patient information and imaging conditions of the patient to be imaged in association with the identification information of the cassette used for imaging, and stores the medical image data transmitted from the medical image reader. Is stored in association with the imaging order information based on the identification information.

  In addition, for patients with fractures, cerebrovascular diseases, etc., patients under management in the intensive care unit, etc., medical images are taken at the roundabout using a movable radiation source and cassette for round trips Systems are also known. For example, in Patent Document 1, the imaging order information stored in the control apparatus is transmitted to the mobile terminal as imaging order information for performing round-trip imaging, and the imaging order information for the round-trip imaging target and the imaging order are displayed on the mobile terminal. A system is described in which information is associated with cassette identification information, and imaging order information associated with cassette identification information is returned to a control device after imaging.

By the way, in recent years, in order to acquire medical image data, an FPD (Flat Panel Detector) that detects radiation and acquires it as digital image data has been used together with the cassette incorporating the above-described stimulable phosphor sheet. ing. The FPD can store a plurality of image data while the cassette can record only one image (see Patent Document 2). For this reason, it is conceivable to improve the efficiency of round trip imaging by using FPD.

  However, when a portable FPD is simply introduced into a conventional medical imaging system using a cassette and used for rounds, the imaging order information and medical image data cannot be associated with each other on a 1: 1 basis. It becomes. In addition, when there is editing such as change, addition, deletion, etc. of the imaging order information at the roundabout imaging destination, it is troublesome to return to the control device, edit the imaging order information, and send it again to the mobile terminal. Furthermore, in the medical image photographing system using the cassette, the medical image data acquired by photographing is displayed in units of patients, but when confirming a plurality of image data photographed in the round-trip destination, it is displayed in units of patients. However, the operation such as switching the patient to be displayed is necessary and complicated.

  Furthermore, in the region 234c displaying the imaging region and the imaging direction displayed on the right side of the input screen 234, the imaging region and the imaging direction selected by instructing the instruction button described above are, for example, “chest It is displayed as “Other oblique position”. Patient information and imaging conditions are input on the input screen 233 and the input screen 244, and when the “reservation” button displayed on the lower left lower portion of the input screen 234 is pressed, the input patient information and imaging order information of the imaging conditions are displayed. The generated imaging order information is additionally displayed on the portable list screen 232.

  Hereinafter, various processes executed in each device constituting the medical image capturing system 100 in the portable FPD mode or the portable CR mode will be described. In the CR cassette 50 and the FPD 70, it is assumed that all image data has been erased, and that the shooting order count value m of the FPD 70 has been initialized to zero.

  First, a portable shooting preparation process for causing the mobile terminal 10 to acquire shooting order information from the control device 20 will be described. FIG. 9 is a flowchart showing the portable photographing preparation process. The portable shooting preparation process is realized by the cooperation of the CPU 21 and the program stored in the storage device 26 when the portable mode is set by the input unit 22.

  When the imaging order information to be transmitted is selected by the operation of the input unit 22 by the engineer on the portable list screen 232 and a transmission instruction is input (step S1), the CPU 21 controls the first I / F 27 to carry the portable information. It is determined whether or not the terminal 10 is attached to the cradle 201 (step S2). If it is determined that the mobile terminal 10 is not attached to the cradle 201 (step S2; NO), the CPU 21 displays an error on the display unit 23 (step S6), and the portable photographing preparation process is terminated.

  On the other hand, when determining that the mobile terminal 10 is attached to the cradle 201 (step S2; YES), the CPU 21 acquires the imaging order information instructed to be transmitted in step S1 from the imaging order information file 261, and the first I The acquired imaging order information is transmitted to the portable terminal 10 together with the mode setting information via / F27 and the cradle 201 (step S3). The mode setting information is information indicating the operation mode set on the menu screen 231. Then, the CPU 21 sets the transmission completion flag of the transmitted imaging order information in the imaging order information file 261 to ON (step S4), and further stores the mode setting information in the mode setting item of the transmitted imaging order information ( Step S5), the portable mode photographing preparation process is terminated.

  In accordance with the above-described portable photographing preparation process in the control device 20, the photographing order information acquisition process is executed in the portable terminal 10 attached to the cradle 201. FIG. 10 is a flowchart showing imaging order information acquisition processing. The imaging order information acquisition process is realized by the cooperation of the CPU 11 and the program stored in the storage device 16 when the operation mode of the portable terminal 10 is set to the reception mode by the operation unit 12. In the present embodiment, it is assumed that the reception mode can be set only when the transmission completion flags of the imaging order information stored in the imaging order information file 161 are all ON.

  CPU11 discriminate | determines whether the portable terminal 10 was mounted | worn with the cradle 201 of the control apparatus 20 according to the detection signal output by I / F14 (step S11).

  When the mobile terminal 10 is mounted on the cradle 201 (step S11; YES), the CPU 11 controls the I / F 14 and receives mode setting information and photographing order information transmitted from the control device 20 (step S12). . Then, the CPU 11 stores the received mode setting information in the RAM 15, stores the received shooting order information in the shooting order information file 161 of the storage device 16 (step S13), and sets the shooting order count value n to 0. (Step S14), and the photographing order information acquisition process is terminated.

  When the portable imaging preparation process and the imaging order information acquisition process are completed, the technician moves to the hospital room where the imaging is performed with the portable terminal 10, the radiation source 40, the CR cassette 50 or the FPD 70 used for imaging. Note that the patient list screen 131 shown in FIG. 11 can be displayed on the display unit 13 of the mobile terminal 10 in accordance with a predetermined operation of the operation unit 12. The patient list screen 131 displays a part of patient information included in the imaging order information acquired by the imaging order information acquisition process described above. As shown in FIG. 11, the patient list screen 131 is provided with an area 131a indicating patient information, and the area 131a is provided with items for displaying a patient ID, a patient's name, and a hospital room. Specifically, numeric data “0001” is displayed in the patient ID item, and text data “Yamada Ichiro” is displayed in the name item. From this patient list screen 131, the engineer can confirm the hospital room where the patient to be photographed is located.

Next, in the hospital room where imaging is performed, with respect to imaging execution result acquisition processing for displaying imaging order information, associating cassette ID or FPDID with imaging order information, and associating imaging order information with imaging order using the mobile terminal 10 explain.
FIG. 12 is a flowchart illustrating a shooting execution result acquisition process executed by the CPU 11 of the mobile terminal 10. The photographing execution result acquisition process is realized by the cooperation of the CPU 11 and a program stored in the storage device 16.

  First, the CPU 11 controls the bar code reader 17 to read a bar code attached to the patient's bedside or a part of the patient's body to obtain a patient ID (step S21). Next, the CPU 11 acquires imaging order information corresponding to the read patient ID from the imaging order information file 161 (step S22).

Subsequently, the CPU 11 displays the acquired photographing order information on the display unit 13 (step S23).
FIG. 13 is a diagram showing a display screen 132 that displays imaging order information of the corresponding patient when the patient ID is acquired by the barcode reader 17 of the mobile terminal 10. As shown in FIG. 13, the display screen 132 is provided with an area 132a for displaying patient information and an area 132b for displaying imaging conditions. In the area 132a for displaying patient information, items for displaying the patient name, patient ID, sex, age, and hospital room are provided, and corresponding data is displayed for each item. The area 132b for displaying the imaging conditions is provided with an item 132b-1 for displaying the imaging condition (imaging site and imaging direction) and an item (ID item) 132b-2 for displaying the cassette ID or FPDID. In the ID item 132b-2, data acquired by the barcode reader 17 of the mobile terminal 10 is displayed simultaneously with the reading. For example, when any one of the shooting condition information displayed by the operation unit 12 is pressed and selected, and the cassette ID or FPDID is acquired by the barcode reader 17, the selected shooting in the shooting order information file 161 is performed. The acquired ID is stored in the ID item of the shooting order information corresponding to the condition, and the acquired cassette ID or FPDID is displayed in the ID item 132b-2 corresponding to the selected shooting condition on the display screen 132. The
Further, as shown in FIG. 13, an “edit” button 132 c for instructing editing of data of the displayed photographing order information is provided at the lower part of the display screen 132 and is input from the operation unit 12. According to the instruction, the data can be edited (changed, added, deleted). In other words, if it is necessary to add or change the scheduled imaging due to the patient's condition at the round-trip, or if the scheduled imaging is difficult due to a serious condition, etc. It is possible to add, change, and delete (cancel) information.

  The CPU 11 determines whether or not an instruction to edit the imaging order information displayed on the display unit 13 is input by the operation unit 12, and determines that an instruction to edit the imaging order information is not input (step S24). NO), the process proceeds to step S27. On the other hand, if it is determined that an instruction to edit the shooting order information is input (step S24; YES), the CPU 11 edits the shooting order information according to the input content and stores it in the shooting order information file 161 (step S25). ). The editing means is realized by these steps S24-25.

The editing instruction and editing in step S25 can be performed from the display screen 132, for example. For example, when the “edit” button 132c is pressed, the CPU 11 changes the display of the buttons displayed at the bottom of the display screen 132, and includes an “add” button, a “delete” button, and a “change” button (not shown). ) Is displayed.
When the “add” button is pressed by the operation unit 12 on the display screen 132, the CPU 11 displays an input screen 133 shown in FIG. The input screen 133 is provided with an area 133a for displaying an instruction button for instructing an imaging region as an imaging condition and an area 133b for displaying an instruction button for instructing an imaging direction. When any of the instruction buttons for instructing the imaging region is pressed by the operation unit 12, the CPU 11 displays an imaging direction instruction button corresponding to the pressed imaging region. FIG. 14 shows a case where an instruction button for instructing “chest” is pressed. When any of the imaging direction instruction buttons displayed by the operation unit 12 is pressed, the CPU 11 performs imaging using the pressed imaging region and imaging direction for the patient with the patient ID acquired in step S21. Order information is added to the imaging order information file 161, and an addition flag is set.
When any shooting condition displayed in the shooting condition display area 132 b is pressed by the operation unit 12 on the display screen 132 and the “Delete” button is pressed, the CPU 11 performs the corresponding shooting in the shooting order information file 161. A deletion flag is set in the order information, that is, the imaging order information having the patient ID acquired in step S21 and having the imaging condition pressed on the display screen 132. Here, even if the shooting order information is instructed to be deleted, the deletion flag is set in the corresponding shooting order information without deleting the data of the shooting order information itself, so that post-shooting end processing (to be described later) 16), after returning the imaging order information to the control device 20 by the image data association processing (see FIG. 17), an engineer or the like can confirm that the corresponding imaging order has been deleted (cancelled) in the control device 20. Can be displayed. In the mobile terminal 10, the CPU 11 displays “cancel” on the imaging order information on the display screen 132, and displays the imaging order information instructed to “delete” so that the technician can identify it.
When any shooting condition displayed in the shooting condition display area 132b is pressed by the operation unit 12 on the display screen 132 and the “change” button is pressed, the CPU 11 causes the display unit 13 to display the input screen 134 (FIG. (Not shown). The input screen 134 is the same display as the input screen 133 shown in FIG. When the changed imaging part and imaging direction are pressed from the input screen 134, the CPU 11 has the corresponding imaging order information in the imaging order information file 161, that is, the patient ID acquired in step S21, and the display screen. The imaging condition of the imaging order information having the imaging condition pressed in 132 is changed to the imaging condition of the imaging region and imaging direction pressed on the input screen 134, and a change flag is set.

  After editing, the CPU 11 determines whether there is uncaptured imaging order information among the imaging order information corresponding to the patient ID read in step S21. (S26; YES), the process proceeds to step S27. The uncaptured radiographing order information corresponds to the radiographing order information corresponding to the patient ID read in step S21, in which none of the deletion flag, cassette ID, or FPDID is associated with the radiographing order information file 161. If it is determined that there is no uncaptured shooting order information (step S26; NO), the CPU 11 ends this process.

  In step S27, the photographing order information to be photographed next is pressed and selected from the photographing order information displayed on the display unit 13 by the operation unit 12 (the “OK” button 132d in FIG. 13 is pressed). ) And (step S27), the CPU 11 increments the count value n of the photographing order by 1 (step S28), and controls the barcode reader 17 to read the barcode attached to the CR cassette 50 or FPD 70 for photographing. The cassette ID or FPDID is acquired (step S29). When the mode setting is the portable FPD mode, it is possible to shoot a plurality of images. Therefore, as shown in FIG. 13, the display screen 132 is instructed to use the same FPD 70 used for the previous shooting. For example, a “Continue” button 132e may be provided, and when the “Continue” button 132e is pressed by the operation unit 12, the same ID as the previously acquired FPDID may be automatically acquired. Then, the CPU 11 stores the acquired cassette ID or FPDID in the ID item of the shooting order information file 161 in association with the selected shooting order information, and the shooting order stored in the shooting order counter n is selected. The process is stored in the shooting order item of the shooting order information file 161 in association with the shooting order information (step S30), and the process proceeds to step S31.

  Here, after inputting the cassette ID or FPDID used for the selection of the next imaging target imaging order information and imaging by the above processing, the engineer selects the selected imaging using the CR cassette 50 or FPD 70 of the input ID. Radiographing is performed under the imaging conditions of the order information. The CR cassette 50 can store only one sheet of image data. The FPD 70 can store a plurality of image data. The photographing process in the FPD 70 will be described later.

  In step S31, the CPU 11 determines whether there is uncaptured imaging order information among the imaging order information corresponding to the patient ID read in step S21, and determines that there is uncaptured imaging order information ( Step S31; YES), the process returns to Step S24, and the processes after Step S24 are repeatedly executed. If the CPU 11 determines that there is no uncaptured shooting order information (step S31; NO), the process ends. When the imaging execution result acquisition process ends, the CPU 11 displays the patient list screen 131 on the display unit 13. In the patient list screen 131, it is desirable to display the patient information of a patient who has been photographed so as to be identifiable by shading.

The imaging execution result acquisition process is repeatedly executed for each patient.
Here, the FPD photographing process executed for each photographing in the FPD 70 will be described. FIG. 15 is a flowchart showing the FPD photographing process. This FPD photographing process is realized by the cooperation of the CPU 71 and a program stored in the storage device 76.

  The radiation irradiated by the radiation source 40 and transmitted through the imaging region of the patient is detected by the radiation detection unit 73, and the detected radiation is converted into an electrical signal and accumulated in each pixel of the radiation detection unit 73 (step S41). ) The CPU 71 reads all electrical signals accumulated in the radiation detection unit 73 and acquires medical image data (step S42).

  Subsequently, the CPU 71 increments the count value m of the imaging order by 1 (step S43), stores the acquired medical image data in association with the imaging order m in the storage device 76 (step S44), and ends the FPD imaging process. .

  After the imaging of all patients is completed, the technician moves to an arbitrary control device 20, sets the mobile terminal 10 to the transmission mode using the operation unit 12, and then attaches the mobile terminal 10 to the cradle 201 of the control device 20. As a result, the post-shooting end processing for transmitting the shooting order information and the shooting execution information from the mobile terminal 10 to the control device 20 is executed.

  FIG. 16 is a flowchart showing post-shooting processing executed by the CPU 11 of the mobile terminal 10. This photographing end process is realized by the cooperation of the CPU 11 and the program stored in the storage device 16 when the operation unit 12 is instructed to shift to the transmission mode.

  First, the CPU 11 determines whether or not the mobile terminal 10 is mounted on the cradle 201 of the control device 20 according to the detection signal output from the I / F 14 (step S50). If it is determined that the mobile terminal 10 is attached to the cradle 201 (step S50; YES), the CPU 11 transmits the mode setting information stored in the RAM 15 to the control device 20 (step S51), and the transmission end flag is OFF. Shooting order information and shooting execution information (including ID items, shooting order, edit flag, etc.) are acquired from the shooting order information file 161 and transmitted to the control device 20 (step S52).

  Next, the CPU 11 sets a transmission end flag to ON for the transmitted imaging order information (step S53).

  Next, the CPU 11 proceeds to step S54, determines whether or not unsent imaging order information is in the imaging order information file 161 (step S54), and determines that there is unsent imaging order information (step S54). (S54; YES), the process returns to step S52, and the processes after step S52 described above are repeated. On the other hand, when it is determined that the transmission end flag ON is set for all the imaging order information stored in the imaging order information file 161 (step S54; NO), the CPU 11 ends the post-imaging end processing.

  When the post-shooting process is completed, the technician, when shooting with the FPD 70, attaches the FPD 70 used for shooting to the cradle 202 of the control device 20 that has performed the post-shooting process. When the CPU 71 of the FPD 70 detects that the FPD 70 is mounted on the cradle 202 of the control device 20 in accordance with the detection signal output from the I / F 74, the CPU 71 executes a data transmission process. That is, the CPU 71 sequentially acquires the medical image data and the corresponding imaging order from the storage device 76, associates the imaging order and its own FPDID with the medical image data, and transmits the medical image data to the control device 20 through the I / F 74. When the transmission of all the medical image data stored in the storage device 76 is completed, the CPU 71 ends the data transmission process.

On the other hand, when imaging is performed with the CR cassette 50, the engineer moves to one of the medical image reading devices 30 and reads the barcode of the CR cassette 50 used for imaging with the barcode reader of the medical image reading device 30. At the same time, the CR cassette 50 that has read the barcode is attached to the medical image reading apparatus 30 to read the medical image data. When the CR cassette 50 is attached, the medical image reading device 30 temporarily stores the cassette ID read by the barcode reader in a memory, reads the radiation image accumulated in the attached CR cassette 50, and obtains medical image data. To get. Then, the read medical image data is associated with a cassette ID, and is transmitted to the control device 20 notified in advance as a transmission destination via the network N.
The control device 20 notified in advance as the transmission destination is the control device 20 to which the mobile terminal 10 is attached and the imaging order information is transmitted from the mobile terminal 10 during the above-described post-shooting end processing. When the imaging order information is transmitted from the mobile terminal 10, the control device 20 executes an image data association process (see FIG. 17) described later, and when the received imaging order information is in the portable CR mode, the imaging order is received. The cassette ID associated with the information and the transmission destination (such as the IP address of the own apparatus) of the medical image data corresponding to the cassette ID are notified to each of the medical image reading apparatuses 30, and the medical image reading apparatus 30 uses the medical ID. Even if the image data is read, the medical image data is transmitted to the own apparatus.

  FIG. 17 is a flowchart showing image data association processing executed by the CPU 21 of the control device 20. The image data association processing is processing for associating the imaging order information transmitted from the mobile terminal 10 with the image data transmitted from the FPD 70 or the medical image reading device 30.

  The CPU 21 determines whether or not the mobile terminal 10 is mounted on the cradle 201 of the control device 20 according to the detection signal output from the first I / F 27 and determines that the mobile terminal 10 is mounted ( Step S60; YES), the mode setting information transmitted from the attached mobile terminal 10 is received, and reception of the imaging order information and the imaging execution information is started (step S61).

  Next, the CPU 21 determines whether or not an additional flag is set in the shooting execution information of the received shooting order information, and if it is determined that the additional flag is set (step S62; YES), the received shooting order information. A shooting ID is assigned to the information and additionally registered in the shooting order information file 261 (step S63), and the process proceeds to step S65.

  On the other hand, when the CPU 21 determines that the additional flag is not set in the received imaging order information (step S62; NO), the corresponding imaging order information (received) stored in the imaging order file 261 in the storage device 26 is received. The shooting order information and the shooting ID information whose shooting ID matches are searched, and the searched record is updated with the contents of the received shooting order information and shooting execution information (step S64), and the process proceeds to step S65. To do.

  In step S <b> 65, the CPU 21 determines the mode setting information received from the mobile terminal 10. If the mode setting information is determined to be the portable CR mode (step S <b> 65; YES), the CPU 21 receives it via the communication control unit 24. The cassette ID included in the imaging execution information of the imaging order information and the transmission destination information (such as the IP address of the own apparatus) of the medical image data corresponding to the cassette ID are notified to each of the medical image reading apparatuses 30 (step S66). The process proceeds to step S67. On the other hand, when the CPU 21 determines that the mode setting information received from the portable terminal 10 is the portable FPD mode (step S65; NO), the CPU 21 proceeds to the process of step S67.

  In step S67, the CPU 21 determines whether or not the next shooting order information and shooting execution information have been received from the attached mobile terminal 10 via the first I / F 27, and the next shooting order information and shooting are determined. If it is determined that the execution information has been received (step S67; YES), the process returns to step S62. When reception of the imaging order information from the portable terminal 10 is completed (step S67; NO), the process proceeds to step S68.

  In step S <b> 68, the CPU 21 determines the mode setting information received from the mobile terminal 10, and if the mode setting information is determined to be the portable FPD mode (step S <b> 68; YES), via the second I / F 28 and the cradle 202. Then, it waits for the start of reception of medical image data from the FPD 70 (step S69). Here, as described above, the FPD 70 transmits the captured medical image data to the control apparatus 20 in association with the FPDID and the imaging order of the own apparatus. That is, the medical image data received via the second I / F 28 is associated with the FPDID and the imaging order.

  When reception of medical image data from the FPD 70 is started (step S69; YES), the CPU 21 stores the received medical image data in the storage device 26 in association with the imaging order information based on the FPDID and the imaging order sequentially. (Step S70). Specifically, the imaging order information including the FPDID associated with the received medical image data (excluding those for which the deletion flag is set) is arranged in order of the imaging order from the smallest (early), and the received medical image data Correspond in order from the smallest shooting order. As a method of associating the imaging order information with the medical image data, for example, the imaging order information is written in the header part of the medical image data, and the image ID for identifying the medical image data is written in the image ID item of the imaging order information. Can be performed.

  Then, the CPU 21 displays a plurality of medical image data received from the same FPD 70 across the patient on the screen of the display unit 23 (step S71). FIG. 18 is a diagram showing a medical image display screen 235 displayed on the display unit 23 in step S71 of FIG. As shown in FIG. 18, the medical image display screen 235 has a configuration in which medical images of a plurality of patients received from the FPD 70 are displayed on the same screen, that is, a configuration in which the images are displayed across the patients.

  The medical image display screen 235 includes an area 235a for displaying engineer information, an area 235b for displaying patient information, an area 235c for displaying medical images, and an area 235d for displaying imaging conditions for each medical image. On the same screen, four types of medical images can be displayed. Specifically, an area for displaying engineer information at the upper left end of the medical image display screen 235 is provided with an item for displaying text data of “Taro Suzuki” as the name of the engineer. The medical image displayed on the left end will be described. In the area 235b for displaying patient information, an item for displaying numeric data “0001” as a patient ID and text data “Yamadaichiro” as a name are displayed. And an item to be provided.

  Below that, an area 235c for displaying a medical image is provided. The medical image, an item for displaying numeric data “170” as a reading device ID, and an item for displaying text data “normal” as a resolution are provided. Is provided. In addition, an area 235d for displaying photographing conditions is provided at the lower part, and an item for displaying text data of “chest and other oblique positions” as photographing conditions and an item for displaying numerical data of “01000108022016” as cassette IDs. Is provided.

As shown in FIG. 18, on the medical image display screen 235, four medical images of two patients “Yamada Ichiro” and “Sakura Taro” are displayed on the same screen.
In this way, when medical images of a plurality of patients are taken at a round-trip destination in a single round in the portable FPD mode, the taken medical images can be displayed on the same screen even if the patients are different. There is no need to select each patient in order to display the next patient as in the screen for displaying a medical image for each patient, and the operability is improved by eliminating the trouble of displaying the medical image. Can do. In the FPD 70, unlike the CR cassette 50 that can record only one image, a plurality of images can be accumulated. Therefore, it is assumed that a plurality of patients are visited, and the medical images taken are displayed across the patients. Is particularly preferred.

  On the other hand, when determining that the mode setting information is the portable CR mode (step S68; NO), the CPU 21 waits for the start of reception of medical image data from the medical image reading device 30 via the communication control unit 24. (Step S72). Here, as described above, the medical image reading device 30 transmits the medical image data read from the CR cassette 50 to the control device 20 in association with the cassette ID. That is, the cassette ID is associated with the medical image data received via the communication control unit 24.

  When reception of medical image data from the medical image reading device 30 is started (step S72; YES), the CPU 21 sequentially associates the received medical image data with the imaging order information based on the cassette ID in the storage device 26. Store (step S73). Specifically, the medical image data is associated with the imaging order information having a cassette ID that matches the cassette ID associated with the received medical image data. As a method of associating the imaging order information with the medical image data, for example, the imaging order information is written in the header part of the medical image data, and the image ID for identifying the medical image data is written in the image ID item of the imaging order information. Can be performed.

Then, the CPU 21 displays the received medical image for each patient on the screen of the display unit 23 (step S74).
FIG. 19 is a diagram showing a medical image display screen 236 displayed on the display unit 23 in step S74 of FIG. As shown in FIG. 19, the medical image display screen 236 is configured to display the medical image received from the CR cassette 50 on the same screen for each patient.

  Specifically, the medical image display screen 236 includes an area 236a for displaying engineer information, an area 236b for displaying patient information of a patient who is an image display target, and a plurality of medical images and imaging conditions. An area 236c is provided, and four types of medical images for the same patient can be displayed on the same screen. In FIG. 19, a medical image of the patient “Taro Sakura” is displayed on the same screen on the medical image display screen 236. Conventionally, in a CR medical image capturing system, since it is common to display a medical image for each patient, a medical image is displayed for each patient in the portable CR mode.

  Through the series of processes described above, medical image data is acquired in the portable mode and associated with the imaging order information. When imaging order information is added or deleted at the round-trip destination, since the addition flag and deletion flag are set in the corresponding imaging order information, any imaging order information in which any imaging order information is added or deleted Can be identified. Therefore, when returning (transmitting) the imaging order information to the control device 20, the CPU 11 of the mobile terminal 10 transmits the total number of imaging orders to be transmitted, the number of added imaging order information, and the deleted imaging order information. The number of cases is transmitted to the control device 20, and the CPU 21 of the control device 20 displays the total number of received shooting order information, the number of added items, and the number of deleted items together with the number of pieces of shooting order information transmitted to the mobile terminal 10 in advance. It is good also as a structure which asks the engineer etc. to judge whether overwriting is possible, etc., and inputs a judgment result. With such a configuration, it is possible to improve the reliability of association between imaging order information and medical image data. When displaying a list of shooting order information on the display unit 23, an icon indicating “cancel” is displayed on the deleted shooting order information, or an icon indicating “added” is added to the added shooting order information. It is preferable to display the addition and deletion of the imaging order information so that the engineer can confirm.

On the other hand, in the control device 20, when the normal CR mode or the normal FPD mode is selected from the menu screen 231 shown in FIG. 6 by the input unit 22, medical image data is acquired by the following processing and associated with the imaging order information. .
First, the CPU 21 causes the display unit 23 to display a photographing order information list screen (not shown). When shooting order information is selected from the shooting order information list screen by the operation of the input unit 22, the CPU 21 controls the barcode reader 29 and is used for shooting, which is arranged facing the barcode reader 29 by the technician. The barcode of the CR cassette 50 or FPD 70 is read to obtain the cassette ID or FPDID. In the normal FPD mode, the CPU 21 also acquires the order in which the shooting order information is selected. The cassette ID or FPDID acquired in the ID item of the selected imaging order information and the imaging order are associated with each other and stored in the imaging order information file 261. In the normal CR mode, each medical image reading device 30. In the normal FPD mode, the FPD photographing apparatus 80 is informed of the ID (cassette ID or FPDID) associated with the photographing order information and the transmission destination of the image data corresponding to the ID (IP of the own apparatus). Address etc.).

The engineer selects the photographing order information, and registers the barcode of the CR cassette 50 or FPD 70 used for the photographing by the barcode reader 29 of the control device 20, conveys the registered CR cassette 50 or FPD 70 to the photographing room, Take a picture.
When the CR cassette 50 is mounted on the CR imaging device 90 and imaging is performed, the technician causes the barcode reader of the medical image reading device 30 to read the barcode of the CR cassette 50 that has been captured after imaging, and then the CR The cassette 50 is attached to the medical image reading device 30 and the medical image data recorded in the CR cassette 50 is read. When the CR cassette 50 is attached, the medical image reading device 30 temporarily stores the cassette ID read by the barcode reader in a memory, reads the radiation image accumulated in the attached CR cassette 50, and obtains medical image data. To get. Then, the read medical image data is associated with a cassette ID, and is transmitted to the control device 20 that has been notified in advance as the transmission destination (has performed cassette registration) via the network N.

  On the other hand, when the FPD photographing apparatus 80 is mounted on the FPD photographing apparatus 80 and photographing is performed, the FPD photographing apparatus 80 acquires medical image data, FPDID, and photographing order from the photographed FPD 70 and converts them into medical image data. The FPDID and the shooting order are associated with each other and transmitted to the control device 20 that has been notified in advance as a transmission destination (having FPD registration) via the network N.

When the control device 20 receives the medical image data and the cassette ID via the communication control unit 24, the CPU 21 stores the received medical image data in the storage device 26 in association with the imaging order information based on the cassette ID. Specifically, the medical image data is associated with imaging order information having an ID that matches the cassette ID associated with the received medical image data. As a method of associating the imaging order information with the medical image data, for example, the imaging order information is written in the header part of the medical image data, and the image ID for identifying the medical image data is written in the image ID item of the imaging order information. Can be performed. When receiving the medical image data, the FPDID, and the imaging order via the communication control unit 24, the CPU 21 stores the received medical image data in the storage device 26 in association with the imaging order information based on the FPDID and the imaging order. .
Then, the CPU 21 displays the received medical image on the screen of the display unit 23 for each patient.

  As described above, according to the medical imaging system 100 of the present embodiment, when imaging is performed based on imaging order information at a roundabout, the imaging order information and cassette ID or FPDID used for imaging are used in the mobile terminal 10. Register the association with. In addition, when there is a change in the imaging situation according to the condition of the patient at the round-trip destination, the imaging order information stored in the mobile terminal 10 is edited, and the contents according to the imaging situation are stored. After the photographing is finished, the mobile terminal 10 transmits photographing execution information including mode setting information, photographing order information, and ID (cassette ID or FPDID) to the control device 20. The control device 20 updates the contents of the shooting order information file 261 stored in the storage device 26 with the received shooting order information and shooting execution information.

  When imaging is performed using the FPD 70, the FPD 70 detects radiation that has passed through the subject, converts it into an electrical signal, and generates medical image data. Then, the generated medical image data is sequentially stored in the storage device 76 in association with the imaging order (generation order). When the cradle 202 is mounted after imaging, the FPD 70 transmits the stored medical image data to the control device 20 in association with the FPDID and imaging order. When receiving the medical image data from the FPD 70, the control device 20 stores the received medical image data in association with the imaging order information based on the FPDID and the imaging order. And the control apparatus 20 displays the medical image received on the display part 23 across a patient.

  On the other hand, when imaging is performed using the CR cassette 50 and the CR cassette and the cassette ID are acquired in the medical image reading apparatus 30, the medical image reading apparatus 30 controls the acquired medical image data in association with the cassette ID. Transmit to device 20. When receiving the medical image data and the cassette ID from the medical image reading device 30, the control device 20 stores the received medical image data in association with the imaging order information based on the cassette ID. And the control apparatus 20 displays the medical image received on the display part 23 for every patient.

  Therefore, when imaging is performed using the FPD 70, the control device 20 associates the medical image data with the imaging order information based on the FPDID and the imaging order, so the FPD 70 capable of storing a plurality of medical image data is used. Thus, even when a plurality of medical images are captured for one FPD 70, it is possible to reliably associate the medical image data with the imaging order information. In addition, since the work flow of the engineer at the roundabout is almost the same between when the FPD 70 is used and when the CR cassette 50 is used, it is possible to improve work efficiency. In addition, when imaging is performed at a round-trip destination, if there is a change in imaging status according to the condition of the patient, the imaging order information is edited in the mobile terminal 10 and the edited content is stored in the control device 20. Since it can be automatically reflected in the order information, the engineer returns to the control device and edits the shooting order information and sends it to the mobile terminal again, or the engineer re-enters the changes to the shooting order information into the control device. This makes it possible to improve the efficiency of the round-trip work.

  In the case of the portable FPD mode, medical images taken at a round-trip destination are simultaneously displayed on a display screen across a plurality of patients. Therefore, when a technician checks a plurality of medical images taken at a round-trip destination, a display target is displayed. Therefore, it is possible to efficiently check the medical image without switching the patient.

  The description in the above-described embodiment is an example of a suitable medical image photographing system according to the present invention, and the present invention is not limited to this.

  For example, in the above embodiment, communication between the mobile terminal 10 and the control device 20 and communication between the FPD 70 and the control device 20 are performed via a cradle. However, the present invention is not limited to this, and is performed by wireless communication or the like. It is good as well.

  Further, only one FPD 70 is used, and the FPD 70 has a wireless communication function. After photographing, medical image data stored in the FPD 70 after the technician moves to the vicinity of the control device 20 and performs a wireless communication operation. May be transmitted to the control device 20. In this case, it is not necessary to input the FPDID.

  In addition, it is needless to say that the detailed configuration and the detailed operation of each component of the medical image photographing system 100 according to the present embodiment can be appropriately changed without departing from the spirit of the present invention.
