Background Art

[0002] In recent years, informatization has been promoted in the medical field. For example, medical information management systems such as HIS (Hospital Information System) and RIS (Radiological Information System) are used. In addition, digitalization of image acquisition devices and the like as modalities is also progressing, and it is common to perform imaging based on examination request information received from medical information management systems such as HIS and RIS. This examination request information includes patient information such as patient ID and patient name, as well as imaging information such as the procedure for performing imaging.

[0003] However, when photographing a critically ill patient who has been urgently transported, it is difficult to know the patient name etc. in advance before photographing. In Patent Document 1, in order to cope with such a situation, a workflow is disclosed in which examination request information is temporarily created with dummy imaging information, the modality performs imaging based on the examination request information, and then the correct examination request information is created in the RIS, associated in the modality, and the imaging information can be corrected later.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims. Although a plurality of features are described in the embodiments, not all of these plurality of features are essential for the invention, and the plurality of features may be arbitrarily combined. Further, in the accompanying drawings, the same or similar configurations are given the same reference numerals, and duplicate explanations are omitted.

[0011] (First Embodiment) <Configuration of Radiographic Imaging System> The first embodiment of the disclosed technology will be described with reference to FIG. 1. FIG. 1 is a diagram showing a configuration example of a radiographic imaging system according to the first embodiment. As shown in FIG. 1, the radiographic imaging apparatus 1 in the radiographic imaging system of the present embodiment is connected to an external apparatus via a network 15. The control unit 5 of the radiographic imaging apparatus 1 is connected to a HIS (Hospital Information System) 11 that manages the progress of an examination via the network 15. Further, the control unit 5 of the radiographic imaging apparatus 1 is connected to a RIS (Radiology Information System) 12 that transmits an examination order to the radiographic imaging apparatus 1 via the network 15. Furthermore, the control unit 5 of the radiographic imaging apparatus 1 is connected to a PACS (Picture Archiving and Communication Systems) 13 that manages radiographic images and a printer 14 that prints out radiographic images via the network 15.

[0012] The HIS 11 is a hospital management system and includes a server that manages accounting information. When performing a radiographic imaging, an operator inputs an examination instruction from a terminal (input unit) of the HIS 11. Then, the HIS 11 transmits request information to the radiology department of the hospital that is the request destination for the radiographic imaging. This request information is called an examination order. The examination order includes information such as the department name of the requester, the examination ID, the examination item, and patient information (subject information) regarding the subject.

[0013] When the radiology department of a hospital, which is the recipient of a radiography request, receives an examination order by RIS12, it adds imaging information related to radiography (such as imaging site information, imaging direction information, and procedure information, etc.) as an imaging protocol to the examination order and transmits it to the radiography apparatus 1. The radiography apparatus 1 performs radiography according to the received examination order. The radiography apparatus 1 acquires the captured radiographic image, generates examination information associating the radiographic image with the examination order, and outputs it together with the radiographic image.

[0014] PACS13 is a server mainly for image management. The inspection work, detailed post-processing, and diagnosis work of radiographic images are carried out by a high-definition monitor connected to PACS13. In this way, the radiographic image acquired by the radiography apparatus 1 is transmitted to PACS13.

[0015] In addition, the implementation information of the examination in the radiography apparatus 1 (such as image ID and imaging date and time, etc.) is transmitted to HIS11. The transmitted implementation information is used not only for the progress management of the examination but also for the accounting process after the examination.

[0016] The radiography apparatus 1, HIS11, RIS12, PACS13, and printer 14 are connected via a network 15 composed of, for example, a LAN (Local Area Network) or a WAN (Wide Area Network).

[0017] Each of these devices includes one or more computers. The computer is equipped with, for example, a main control unit such as a CPU, and a storage unit such as a ROM (Read Only Memory) and a RAM (Random Access Memory). In addition, the computer may be equipped with a communication unit such as a network card, and an input / output unit such as a keyboard, a display, and a touch panel. These components are electrically connected by a bus or the like and are controlled by the main control unit executing a program stored in the storage unit.

[0018] As shown in FIG. 1, in the imaging room 100, an X-ray imaging apparatus 1 for performing X-ray imaging is installed. Also installed in the imaging room 100 are an X-ray generation control unit 4 for generating X-rays, an X-ray detector 7 for detecting X-rays transmitted through the subject 10 to capture an X-ray image, and an imaging table 6. The X-ray imaging apparatus 1 includes a display unit 2 for displaying X-ray images and various types of information, an operation unit 3 for the operator to perform operations, and a control unit 5 for controlling each component in the X-ray imaging apparatus. When controlling the display unit 2 as a component, the control unit 5 or each part of the functional configuration included in the control unit 5 functions as a display control unit.

[0019] The X-ray generation control unit 4 sets the imaging conditions of the X-rays in the X-ray generation unit 8 and controls the X-ray generation unit 8. The X-ray generation unit 8 functions as an X-ray source for generating X-rays. The X-ray generation unit 8 is realized by, for example, an X-ray tube and irradiates the subject 10 (for example, a specific part of the subject) with X-rays.

[0020] The X-ray generation unit 8 can irradiate X-rays to a desired irradiation range. A diaphragm (not shown) for shielding X-rays is installed on the irradiation surface of the X-ray generation unit 8. The operator can adjust the irradiation range of the X-rays irradiated from the X-ray generation unit 8 by controlling the diaphragm for shielding X-rays.

[0021] The X-ray imaging system includes an X-ray detector 7 for detecting X-rays irradiated from the X-ray generation unit 8. The X-ray detector 7 detects X-rays transmitted through the subject 10 and outputs image data corresponding to the X-rays. Note that the image data may also be referred to as an X-ray image.

[0022] Specifically, the X-ray detector 7 detects X-rays transmitted through the subject 10 as electric charges corresponding to the transmitted X-ray dose. For example, in the X-ray detector 7, a direct conversion type sensor such as a-Se that directly converts X-rays into electric charges, or an indirect type sensor using a scintillator such as CsI and a photoelectric conversion element such as a-Si is used.

[0023] The radiation detector 7 generates image data by performing A / D conversion on the detected charges and stores it in a storage unit (not shown). The radiation detector 7 can attach image information (image ID, shooting date and time, and transfer status of the image data) to the image data and transfer it to the radiation imaging apparatus 1 together with the image data. The control unit 5 of the radiation imaging apparatus 1 is connected to the radiation detector 7 via a wireless LAN. It is possible to transmit and receive image data, control signals, etc. between the control unit 5 and the radiation detector 7. That is, the image data stored in the radiation detector 7 by radiation imaging is output (transferred) to the control unit 5 via the wireless LAN.

[0024] The display unit 2 is realized by, for example, a liquid crystal display or the like, and displays various information to an operator (for example, a radiographer or a doctor). The operation unit 3 is composed of, for example, a mouse, operation buttons, etc., and inputs various instructions from the operator to each component. Note that the display unit 2 and the operation unit 3 may be realized as an integrated touch panel.

[0025] (Explanation of the Radiation Imaging System) The radiation imaging system of this embodiment will be described in detail with reference to FIG. 2. FIG. 2 is a diagram showing a configuration example of the control unit 5 of the radiation imaging apparatus 1 according to the first embodiment. The radiation imaging apparatus 1 in the radiation imaging system includes a control unit 5 that performs image processing on the radiation image output from the radiation detector 7 and generates an image. The control unit 5 has an application function that operates on a computer. The control unit 5 controls the operation of the radiation detector 7 and outputs a radiation image to the display unit 2 or outputs a graphical user interface (GUI).

[0026] The control unit 5 of the radiation imaging apparatus 1 includes a captured image storage unit 16 that stores the radiation image obtained by the radiation detector 7, and an inspection information generation unit 17 that generates temporary inspection information and imaging protocols associated with the image obtained by the radiation detector 7. The inspection information generation unit 17 can generate a plurality of pieces of inspection information (for example, 104, 106).

[0027] In addition, the control unit 5 includes an inspection request information acquisition unit 18 that acquires inspection request information from the RIS 12, and an inspection request information selection unit 19 that selects between the temporary inspection information generated by the inspection information generation unit 17 and the inspection request information acquired by the inspection request information acquisition unit 18. The control unit 5 includes an association unit 20 that associates the inspection information selected by the inspection request information selection unit 19. The inspection request information selection unit 19 uses information common to at least a part of the information included in the inspection request information associated with one piece of inspection information (104) among a plurality of pieces of inspection information (for example, 104, 106) temporarily generated for performing a plurality of inspections, and selects the inspection request information narrowed down from the plurality of inspection request information as the inspection request information to be associated with another piece of inspection information (106) among the plurality of pieces of inspection information. Here, the information common to at least a part of the information included in the inspection request information includes subject information (for example, including patient ID, etc.) for identifying the subject who undergoes a plurality of inspections, or information on the imaging site of the subject. The inspection request information selection unit 19 selects, as the inspection request information to be associated, the inspection request information in which at least a part of the subject information is common. The association unit 20 associates the inspection request information to be associated selected by the inspection request information selection unit 19 with another piece of inspection information (106).

[0028] Here, the temporary inspection information generated by the inspection information generation unit 17 is temporary inspection information until it is associated by the association unit 20. The temporary inspection information is, for example, inspection information generated in a state where a patient is urgently transported and the personal information of the patient cannot be identified, and "Emergency" can be set as a temporary patient name in the temporary inspection information. Note that the temporary patient name is merely an example and can be changed as appropriate. When the association unit 20 associates the inspection information with the inspection request information, the content of the inspection information is rewritten based on the content of the associated inspection request information. For example, in the inspection information, "Emergency" set as the temporary patient name is rewritten based on the personal information set in the inspection request information.

[0029] <Imaging process> Here, the procedure of processing when taking a radiographic image will be described along the flow of the examination by the radiographic imaging system shown in FIG. 1. The radiographic imaging system (5, 7) includes a radiation detector 7 and a control unit 5 (imaging control device) that controls radiographic imaging using the radiation detector 7.

[0030] First, the operator operates the operation unit 3 of the radiographic imaging apparatus 1, and the display unit 2 is caused to display a imaging protocol input screen as shown in FIG. 3 under the control of the examination information generation unit 17. The imaging protocol input screen includes an imaging protocol list display area 101 for displaying a list of preset imaging protocols 102, a patient information area 103, examination display areas 104, 106, an examination addition button 108, and an examination start button 109.

[0031] By operating the examination addition button 108 by the operator, the examination information generation unit 17 can add an imaging protocol to the examination display area 104. When adding an imaging protocol, for example, the operator may select the imaging protocol 102 to be added from the imaging protocol list display area 101. In the example of FIG. 3, in the examination display area 104, a frontal chest (imaging protocol 105a) and a lateral chest (imaging protocol 105b) are added as imaging protocols.

[0032] Furthermore, when adding an examination, the operator presses the examination addition button 108 again and makes the same selection. In the example of FIG. 3, an examination display area 106 is added, and a frontal abdomen 107a is added as an imaging protocol.

[0033] After the operator adds all the examinations and imaging protocols, the operator presses the examination start button 109. Thereby, the examination to be performed is determined. In accordance with the pressing of the examination start button 109, the control unit 5 of the radiographic imaging apparatus 1 causes the display unit 2 to display an imaging screen as shown in FIG. 4. Here, the imaging screen is the screen used at the time of imaging.

[0034] The imaging screen shown in FIG. 4 basically has a display area similar to the imaging protocol input screen described in FIG. 3. As newly added display areas, as shown in FIG. 4, an image display area 110, a message area 111, and an inspection end button 112 are displayed.

[0035] When the imaging screen is displayed, among all the inspections and imaging protocols, the chest front button (sensor A: imaging protocol 105a) arranged at the uppermost position is in the selected state by default.

[0036] Accordingly, the control unit 5 of the radiation imaging apparatus 1 transmits the imaging conditions (tube voltage, tube current, irradiation time, etc.) set corresponding to the selected imaging method button (imaging method) to the radiation generation control unit 4. Then, the control unit 5 controls the radiation detector 7 according to the set imaging conditions to prepare for imaging. When the preparation is complete, the radiation imaging apparatus 1 transitions to the imaging-enabled state. At this time, a "Ready message" indicating the imaging-enabled state is displayed in the message area 111.

[0037] Subsequently, the operator checks the imaging method and performs imaging settings and patient positioning. When a series of imaging preparations are completed, after the operator checks the imaging-enabled state by referring to the message area 111, the operator presses a radiation irradiation switch (not shown). Then, the radiation imaging apparatus 1 irradiates the subject (specific part of the patient) with radiation by the radiation generation unit 8, and the radiation detector 7 detects the radiation that has passed through the subject. Thereby, the imaging of the radiation image is performed.

[0038] When the imaging is completed, the control unit 5 of the radiation imaging apparatus 1 acquires a captured image from the radiation detector 7 and performs image processing on the acquired captured image based on predetermined image processing conditions. The predetermined image processing conditions are defined in advance corresponding to the imaging method. When the image processing based on the predetermined image processing conditions is completed, the control unit 5 of the radiation imaging apparatus 1 causes the processed captured image to be displayed in the image display area 110. Further, the control unit 5 generates a thumbnail 111a obtained by reducing the captured image and causes the thumbnail 111a to be displayed in the imaging protocol 105a.

[0039] The operator repeats the above-described procedure to perform imaging of the imaging protocols 105a, 105b, and 107a in all the inspection display areas 104 (inspection 1) and inspection display areas 106 (inspection 2). When all the imaging is completed, the operator presses the inspection end button 112. Thereby, a series of inspections is completed. In accordance with the pressing of the inspection end button 112, the control unit 5 of the radiation imaging apparatus 1 causes the inspection information association screen as shown in FIG. 5 to be displayed on the display unit 2. The inspection information association screen is a screen used when selecting which inspection request information to rewrite when associating temporary inspection information with the inspection request information.

[0040] The inspection information association screen is configured to have a display area similar to the inspection and imaging protocol described with reference to FIG. 4. As newly added display areas, as shown in FIG. 5, an inspection request information list 120, a list acquisition button 121, a cancel button 122, a return button 123, and a next button 124 are displayed.

[0041] Furthermore, an inspection request information search unit 125 is displayed above the inspection request information list 120. When a plurality of pieces of information are displayed in the inspection request information list 120, a search can be performed by setting values for the items. As the items, the inspection request information search unit 125 includes a patient name search unit 126, a date of birth search unit 127, an age search unit 128, a patient ID search unit 129, and a gender search unit 130.

[0042] When the inspection information association screen of FIG. 5 is displayed, among all the inspections, the inspection display area 104 arranged at the topmost is in the selected state by default. When the operator presses the list acquisition button 121, the inspection request information is acquired from the RIS 12, and the inspection request information is listed and displayed in the inspection request information list 120. The operator selects the inspection request information to be associated from the inspection request information list and presses the next button 124. By pressing the button 124, the association unit 20 associates the inspection displayed in the inspection display area 104 with the selected inspection request information.

[0043] When the association process is performed, the inspection to be associated is changed from the inspection 1 in the inspection display area 104 to the inspection 2 in the inspection display area 106. In response to the change of the inspection to be associated, the inspection 2 in the inspection display area 106 is displayed so as to indicate the selected state. Thereafter, according to the overall selection process flowchart of FIG. 6, the selection process performed after the first association process will be described.

[0044] In the selection process, the processes of steps S101 to S105 are performed. Since there are more detailed flowcharts for steps S104 and S105, they will be described there.

[0045] First, in step S101, the inspection request information selection unit 19 analyzes the information about the inspection (urgent inspection) that was associated for the first time. The information to be analyzed may include, for example, the inspection start date and time when the inspection (urgent inspection) was started, the imaged part, the DICOM code value corresponding to the imaged part, the actually taken image, and the unique information assigned to the taken image, etc. The analyzed information is retained. Also, if there is information input by the operator during imaging, the input information is also retained.

[0046] In step S102, the inspection request information selection unit 19 analyzes the inspection request information (bound inspection request information) associated with an inspection (urgent inspection) in the first association process. Regarding the inspection request information, for example, it can be manually created by an operator in the requesting department or automatically created by the system. The inspection request information acquisition unit 18 receives the created inspection request information from the RIS 12, and the inspection request information selection unit 19 analyzes and stores the information. In step S103, the inspection request information selection unit 19 similarly analyzes and stores the inspection request information for which no association has been made.

[0047] The specific process flow of the process in step S104 will be described in the flowchart of FIG. 7. In the repetitive process of steps S201 to S205, all inspection request information is checked. The inspection request information received from the RIS 12 is not just one piece, but there may be multiple pieces of inspection request information received. Also, the inspection request information may be related to inspections of other patients regardless of a specific patient's inspection. Therefore, in steps S201 to S205, the inspection request information selection unit 19 checks all the inspection request information stored in the inspection request information acquisition unit 18.

[0048] The actual process is carried out after step S202. In step S202, the inspection subject to the first association analyzed in step S101 is targeted. Using the patient ID of the urgent inspection as a key, a value related to the patient ID of the inspection request information is searched. The target patient ID is specified in all the inspection request information. By comparing with the same patient ID as in the first association and making a selection, inspection request information with high relevance can be shown to the operator. Therefore, this comparison process is carried out for all the inspection request information.

[0049] However, the patient IDs assigned to the test request information are often just a list of numbers, and especially in larger hospitals, the number of digits increases. Therefore, if the patient ID assigned to the test request information is incorrect, simply performing a comparison process in step S202 may result in the subsequent information not being displayed at all. In step S202, a search with a certain degree of flexibility is performed, not limited to the case where the patient IDs exactly match. It is sufficient if at least some of the information included in the test request information is common. For example, considering that the number of digits may be insufficient, even if there are some characters before and after in a regular expression or the like, it is selected as the target. Furthermore, when the same character continues within the characters constituting the patient ID, it is conceivable that the continuation may be an error. Conversely, it is also conceivable that having one more character continue may be correct. In step S202, when the test request information selection unit 19 determines that the test request information is close to the patient ID of the emergency test that was associated in the first time after considering such data and performing a search (step S202 / YES), the process proceeds to the next step S203.

[0050] In step S203, the test request information selection unit 19 stores it in the storage area for display as the display target. The information stored in the storage area is hereinafter referred to as "stored test request information". Then, the process proceeds to step S205.

[0051] In the determination process of step S202, when it is determined that there is no relevance to the patient ID of the emergency test that was associated (step S202 / NO), the process proceeds to the next step S204.

[0052] In step S204, since there is no information to be the display target, the test request information selection unit 19 does not perform the storage process and proceeds to the next step S205.

[0053] In step S205, the inspection request information selection unit 19 checks whether all the inspection request information has been checked. If there are still items to be checked, the process returns to step S201 and the same process is repeated. In step S205, when all the inspection request information has been checked, the first selection process ends, the process returns to the flowchart of FIG. 6, and the process proceeds to step S105.

[0054] In step S105, the number of pieces of information stored in the storage area for display, which was processed in step S203, is checked. If the number of pieces of information stored in the storage area is 0 (step S105 / YES), since there is no inspection request information that can be processed, the selection process ends.

[0055] In the determination process of step S105, if the number of pieces of information stored in the storage area for display is other than 0 (step S105 / No), the process proceeds to the next step S106.

[0056] In the process of step S106, the inspection request information selection unit 19 of the radiography apparatus 1 causes the display unit 2 to display an inspection information association screen as shown in FIG. 8. For example, the inspection request information selection unit 19 causes the display unit 2 to display at least one inspection request information (for example, the inspection request information 131 displayed in the inspection request information list 120) selected from a plurality of inspection request information as other inspection information (106) and an association target for the other inspection information. The difference from FIG. 5 is that in the initial selection state, the selection display moves from the selected inspection display area 104 to the inspection display area 106, and the inspection display area 106 can be associated.

[0057] In addition, the patient ID selected in the first selection is set in the patient ID search section 129, and the target test request information is displayed in the test request information list 120. The test request information selection section 19 causes the display section 2 to display a button 124 (operation input section) capable of accepting the operator's confirmation result, and the association section 20 associates the test request information 131 to be associated and other test information (106) based on the input from the button 124 (operation input section). As described in the processing flow of FIG. 7, by performing the first selection process, in the second selection process, only the relevant test request information can be displayed, reducing errors and enabling efficient implementation of the association with multiple tests. Note that the selection process of the test request information and the association process between the selected test request information and the test information are not limited to the operator's manual operation and may be performed automatically. For example, the test request information selection section 19 may automatically select the test request information narrowed down from a plurality of test request information as the test request information to be associated with other test information, or the association section 20 may automatically associate the test request information to be associated selected by the test request information selection section 19 and other test information (106).

[0058] The specific processing flow of the second selection process in step S106 will be described with reference to the flowchart of FIG. 9.

[0059] In step S301, the test request information selection section 19 compares two pieces of information. The test request information selection section 19 compares the number of tests for which association has not yet been performed (the number of remaining test information) with the number of stored test request information (the number of remaining test request information). If the respective numbers are the same (step S301 / YES), the process proceeds to step S305. When the number of remaining test information that has not been associated and the number of remaining test request information among a plurality of tests are the same, the test request information selection section 19 selects the remaining test request information as the association target for the remaining test information.

[0060] In step S305, since the number of remaining inspections for which association has not been performed (inspection information) is the same as the number of saved inspection request information (remaining inspection request information), it is highly likely that they are the targets for association. Therefore, the association unit 20 automatically performs the association. At this time, the association unit 20 may cause the display unit 2 to display a confirmation screen indicating that the subsequent inspections will be automatically associated for the user. Also, when there are multiple inspections during the actual association, in the case of completed inspections, they may be sorted in the order of execution, and sorted by the issuance order, reception order, inspection date and time, etc. of the inspection request information, and then associated with the inspection request information.

[0061] In the determination process of step S301, when the number of inspections for which association has not been performed is not the same as the number of saved inspection request information (step S301 / NO), the inspection request information selection unit 19 advances the process to step S302. That is, the inspection request information selection unit 19, among multiple inspections, when the number of remaining inspection information for which association has not been performed is not the same as the number of remaining inspection request information, for each of the remaining inspection information, selects, from the remaining inspection request information, the inspection request information for which at least some of the information on the imaging site of the subject (for example, imaging site, etc.) is common as the inspection request information to be associated.

[0062] In step S302, since the inspection request information selection unit 19 checks all of the saved inspection request information, the process advances to the next step S303.

[0063] In step S303, the examination request information selection unit 19 determines whether the imaging site of the subject in the performed examination is the same as the site information specified in the saved examination request information. The site information of the examination request information corresponds to the "CodeValue" specified by the DICOM tag name. If this value is the same (step S303 / YES), the process proceeds to step S306. Note that even if the values of the DICOM tag names do not exactly match, if the imaging site is included in a general site in the correspondence table between the CodeValue stored in the radiography apparatus 1 and the imaging site, the imaging site may be regarded as the same. That is, if the right hand was imaged in the examination but the hand is specified in the examination request information, the imaging site may be regarded as the same.

[0064] On the selection screen shown in FIG. 8, among the multiple pieces of saved examination request information where the examination display area 106 is the examination currently being associated, the most appropriate examination request information is selected using the site information. At this time, the examination request information may be automatically selected and associated. Also, instead of automatically associating, the appropriate examination request information may be automatically set to the selected state to reduce the operator's workload.

[0065] In step S303, if the site related to the imaging site is not found in the examination request information (step S303 / NO), the process proceeds to step S304.

[0066] In step S304, the examination request information selection unit 19 does not perform processing such as automatically associating or setting to the selected state because no appropriate examination request information is found. Then, the process proceeds to step S307.

[0067] In step S307, it is confirmed whether all the examination request information has been checked. If not all the examination request information has been checked, the process returns to step S302 and the same processing is repeated. If all the examination request information has been checked, the second selection process ends.

[0068] Return to the inspection information association selection screen and perform the first and second selection processes to extract the inspection request information related to the taken inspection. The operator can then select the appropriate inspection request information and perform the association operation.

[0069] However, when returning to the inspection information association selection screen, it may happen that the related inspection request information has not been narrowed down to a certain extent. For example, considering that the operator may select inappropriate inspection request information and perform the association, the inspection request information selection unit 19 checks the relevance based on the inspection request information associated in the first round. At this time, if there are significant differences in the inspection request information associated in the second round compared to the data of the inspection request information associated in the first round, a warning screen 180 (alert screen) as shown in Fig. 10 is displayed. The warning screen 180 (alert screen) is a notification display that informs the operator of the difference in relevance when there is a significant difference in relevance between the associated inspection request information. When there is information different from the common information among the multiple inspection request information selected as the association targets for multiple inspection information, the inspection request information selection unit 19 causes the warning screen 180 to be displayed on the display unit 2 as a notification display that informs of the difference in relevance among the selected multiple inspection request information.

[0070] On the warning screen 180 (alert screen) shown in Fig. 10, a warning content display area 181, a cancel button 182, and an OK button 183 are displayed. Pressing the cancel button 182 cancels the association. Pressing the OK button 183 performs the association. By repeating these operations, the inspection information association selection screen can be terminated when all the inspections on the inspection information association selection screen have been associated.

[0071] According to this embodiment, by performing the first and second selection processes, it is possible to extract inspection request information related to the captured inspection. Further, when unintentional inspection request information is associated, it can be notified by displaying a warning screen (alert screen) on the display unit 2. As a result, it is possible to reduce errors in the association target and improve the efficiency of the association procedure.

[0072] (Second Embodiment) In the process of the first embodiment, in the first selection process (FIG. 7), when the inspection request information to be associated is not found among the inspection request information, the subsequent processes are not performed. In the second embodiment, an example of inquiring the RIS when the inspection request information to be displayed cannot be found as a narrowing-down method will be described.

[0073] Note that the description of the configuration, functions, and operations similar to those of the first embodiment is omitted, and in the second embodiment, the differences from the first embodiment will mainly be described.

[0074] When there is no inspection request information to be associated with other inspection information (for example, 106) among a plurality of inspection request information, the inspection request information acquisition unit 18 sends an acquisition request specifying the information included in the inspection request information associated with one inspection information (for example, 104) as a search condition to an external device (RIS12). In the RIS12, the inspection request information searched based on the search condition is additionally acquired from the external device (RIS12). In this case, the inspection request information selection unit 19 may select, as the inspection request information to be associated with other inspection information (for example, 106), the inspection request information narrowed down from the inspection request information additionally acquired by the inspection request information acquisition unit 18 using the information included in the inspection request information associated with one inspection information (for example, 104). Further, the association unit 20 may associate the inspection request information to be associated with the other inspection information selected by the inspection request information selection unit 19.

[0075] Figure 11 is a flowchart describing the first selection process. From step S401 to step S405, based on the patient ID of the associated examination, all examination request information is retrieved, and the examination request information with high relevance is selected as the display target for processing.

[0076] In step S406, the examination request information selection unit 19 determines whether the number of pieces of examination request information with high relevance is 1 or more as the display target of the examination request information with high relevance. If the number of pieces of examination request information with high relevance is less than 1 (step S406 / No), the process proceeds to step S407.

[0077] In step S407, the examination request information acquisition unit 18 performs acquisition of search request information from RIS12. When acquiring search request information from RIS12, a acquisition request specifying search conditions is sent to RIS12, and the examination request information searched based on the search conditions is acquired from RIS12. As the search conditions, for example, in step S402, the target patient ID is used as the search condition, so this patient ID is also used for searching in the search of examination request information in RIS. Similar to the process of step S202 in Figure 7, it is also necessary to consider that the specification of the patient ID of the examination request information registered in RIS12 may be incorrect.

[0078] For example, in the acquisition request for RIS12, as the imaging protocol, it is possible to search with a forward match or a backward match of DICOM tag information, or a search condition combining them. It is also possible to acquire examination request information with high relevance using these search conditions. Furthermore, it is also possible to further improve the relevance by using the examination date and time, the name of the requesting doctor, the AE title, etc. included in the examination request information associated as additional information. Note that the search conditions listed here are just examples and are not limited to these, and various search conditions may be combined.

[0079] By performing a search without specifying search conditions, it is also possible to obtain all the examination request information existing in the RIS. In that case, for all the examination request information obtained from the RIS, by re-performing the processing from S401 in FIG. 11, highly relevant examinations can be made the display targets again.

[0080] When the operator performs the association, it is necessary to create in advance in the RIS the examination request information including the patient information and the examination information for the number of examinations performed. However, when actually performing the association, it may happen that the examination request information is still being created or that not all the examination request information has reached the radiological imaging apparatus 1 from the RIS. According to this embodiment, even when there is no examination request information to be associated in the received examination request information, by re-importing the examination request information from the RIS12, it becomes possible to perform the association of the target examination request information from among more examination request information.

[0081] (Third Embodiment) In this embodiment, it is assumed that a certain degree of narrowing down is performed when the first selection process for the object to be associated is performed, but the case where the selection process (narrowing down of the examination request information) is not performed as expected will be described. In this embodiment, a configuration for improving the accuracy of relevance using the information of multiple associations when multiple examinations are associated two or more times will be described.

[0082] In this embodiment, when the association by the association unit 20 is performed multiple times and the number of the remaining examination request information is larger than the number of the remaining examination information that has not been associated among the multiple examinations, the examination request information selection unit 19 searches for the locations that are common data in the multiple examination request information in which the association has been performed multiple times, and excludes the examination request information that is different from the common data in the remaining examination request information as the examination request information with low relevance to the remaining examination information.

[0083] Figure 12 is a flowchart for explaining the flow of the first selection process in the third embodiment. In steps S501 to S505, the inspection request information selection unit 19 performs a process of searching all inspection request information based on the patient ID of the associated inspection and selecting inspection request information with high relevance as the display target.

[0084] After that, in step S506, the inspection request information selection unit 19 checks the current number of associations and the inspection request information to be displayed. Regarding the number of associations, if the association has already been performed two or more times, there are already two or more sets of combinations of the completed inspections and the inspection request information. Further narrowing down of the information is performed using these (Condition 1).

[0085] As a further narrowing down, when the number of remaining inspection request information is larger than the number of remaining completed inspections for which associations are still required (number of inspection information) (Condition 2), this information is used to narrow down the information. That is, when both Condition 1 and Condition 2 are satisfied, it becomes possible to exclude inspection request information with low relevance. When these two conditions 1 and 2 are satisfied (step S506 / Yes), the process proceeds to step S507.

[0086] In step S507, the inspection request information selection unit 19 performs an exclusion search to exclude inspection request information with low relevance from the remaining inspection request information using the associated inspection request information that was confirmed in step S506 among the associated completed inspections and inspection request information.

[0087] Since there are already two or more pieces of inspection request information that have been associated, this information is used as the basis. Among the multiple pieces of inspection request information where the associated inspection request information exists as the first piece, the second piece, ··· the nth piece, search for the data in the common part, that is, the parts where the same data (common data) exists in the inspection request information. Specific data includes, for example, patient information for identifying patients such as patient names, in addition to the names of the requesting doctors, AE titles, inspection dates, etc. Note that the examples given here are just examples and are not limited to this example. In the case of highly relevant inspection request information, the data as listed in the specific examples is likely to contain the same data (common data) among the first piece of inspection request information, the second piece of inspection request information, ··· the nth piece of inspection request information.

[0088] On the other hand, in the case of inspection request information with low relevance, it is likely to contain different data. Therefore, first, from the associated inspection request information, extract the items that are the same data and the data set in those items as common data. Compare the extracted data, and perform an exclusion process on the inspection request information that contains different data as inspection request information with low relevance.

[0089] The exclusion process is performed by searching based on whether the items with the same values extracted from the inspection request information and the information set in the items are the same. If the values are different, it is determined that the relevance is low, and identification information for identifying the inspection request information determined to have low relevance is set. As for the setting of the identification information, a flag may be set and marked for the inspection request information with low relevance. This process is performed for all inspection request information.

[0090] For example, as shown in FIG. 5, in the inspection request information search section 125 of the inspection information association selection screen, a user interface for narrowing down based on the on / off state of this flag may be provided. As a result, it becomes possible to intentionally exclude inspection request information with low relevance from the inspection request information list 120. According to the present embodiment, by attaching a flag to inspection request information with low relevance, it becomes possible to easily exclude inspection request information with low relevance as a result, thereby reducing errors in the association target and improving the efficiency of the association procedure.

[0091] (Fourth Embodiment) In the fourth embodiment, a configuration capable of associating not only the association immediately after the end of radiography but also inspections after being put on hold will be described. Note that descriptions of the same configurations, functions, and operations as those in the above embodiments are omitted, and mainly differences from the present embodiment will be described. FIG. 13 is a diagram showing a configuration example of the control unit 5 of the radiography apparatus 1 according to the fourth embodiment. Further, FIG. 14 is a diagram showing a display example of the inspection information association screen displayed on the display unit 2 in the fourth embodiment.

[0092] In the configuration example of the control unit 5 shown in FIG. 13, an inspection information storage unit 21 is added to the configuration example of the control unit 5 described with reference to FIG. 2. The inspection information storage unit 21 is a non-volatile storage device capable of permanently storing information related to inspections. The inspection information storage unit 21 stores information related to inspection information for which the association has been put on hold midway. For example, when the association for one piece of inspection information (e.g., 104) has been completed and the association for other inspection information (e.g., 106) is on hold midway, the inspection request information associated with the one piece of inspection information, the other held inspection information, the one piece of inspection information, and the other inspection information may be stored together with timing information indicating that the association of the inspection request information was performed at the same timing.

[0093] In this embodiment, when resuming the association of other stored inspection information (e.g., 106), the inspection request information selection unit 19 determines whether there is information in which the association of inspection request information was performed at the same timing as the other inspection information based on the timing information stored in the inspection information storage unit 21, and based on the determination, acquires from the inspection information storage unit 21 the inspection request information associated with one piece of inspection information (e.g., 104). Then, the inspection request information selection unit 19 uses information common to at least a part of the information included in the inspection request information to select, as the inspection request information to be associated with the other inspection information, the inspection request information narrowed down from a plurality of inspection request information. Specific processing using the inspection information storage unit 21 will be described later.

[0094] In the first embodiment, the configuration in which the inspection information association selection screen of FIG. 5 is displayed at the timing of finishing the inspection and all associations are performed has been described. However, if it is known in advance that inspection request information corresponding to the inspection has not been created as the association target, the association of each inspection can be postponed. As shown in FIG. 14, on the inspection information association selection screen, hold buttons 190 and 191 are displayed for inspection 1 in the inspection display area 104 and inspection 2 in the inspection display area 106, and by pressing the hold buttons 190 and 191, the association of each inspection can be postponed.

[0095] For example, when the hold button 190 is pressed, the association of the inspection request information for inspection 1 is postponed, and when the hold button 191 is selected, the association of the inspection request information for inspection 2 is postponed. The hold buttons are configured to be selectable for each inspection, and the operator can select the inspection for which the association is to be postponed by selecting the hold button.

[0096] In this embodiment, the postponement of an inspection can be used when the inspection has started but is temporarily interrupted for inspection or patient convenience. An inspection that has been postponed once can be resumed later.

[0097] In the case of FIG. 14, there are two already taken inspections, Inspection 1 and Inspection 2. For example, when it is found that for one of the two inspections, the inspection request information to be associated has not been created yet, the operator may press either of the hold buttons 190 and 191. For example, assume the operator presses the hold button 191 for Inspection 2 in the inspection display area 106. Then, an association is made for the first Inspection 1, and the association operation using the inspection information association selection screen (FIG. 14) is terminated. At that time, in the inspection information storage unit 21, information indicating that Inspection 1 and Inspection 2 have been associated with inspection request information at the same timing is saved. Also, when an association is made for Inspection 1, the associated inspection request information is also saved in the inspection information storage unit 21.

[0098] FIG. 15 is a diagram showing a display example of the hold inspection list screen 200 in the fourth embodiment. FIG. 16 is a diagram for explaining the flow of the selection process in the fourth embodiment. As shown in FIG. 15, the hold inspection list screen 200 includes a hold inspection list 201, a resume inspection button 202, and a display of information regarding Inspection 2 in the inspection display area 106 that has been put on hold by pressing the hold button 191. When the inspection request information is created for the put-on-hold Inspection 2, the operator can resume the association of the put-on-hold Inspection 2 by pressing the resume inspection button 202 from the hold inspection list screen 200.

[0099] After that, when Inspection 2 is completed, the screen display of the display unit 2 transitions to the inspection information association selection screen in FIG. 17 through the processing of the flowchart in FIG. 16 in order to make an association for Inspection 2. In other embodiments, when Inspection 2 in the inspection display area 106 is completed and no inspection association has been made, it immediately transitions to the inspection information association selection screen (for example, FIG. 8). However, in the fourth embodiment, before displaying the selection screen (FIG. 17), the processing of the flowchart in FIG. 16 is performed.

[0100] Steps S101 to S106 are the same processes as the flowchart in FIG. 6. In step S107 of FIG. 16, it is inquired to the inspection information storage unit 21 whether the inspection to be displayed on the inspection information association selection screen (for example, inspection 2) has been associated before. In the fourth embodiment, since inspection 1 and inspection 2 have been associated at the same timing before (step S107 / YES), the process proceeds to step S108.

[0101] In step S108, the inspection request information of another inspection (here, inspection 1) that has been associated at the same timing is acquired. Thereafter, the process proceeds to step S101, the analysis of inspection 2 is performed, and the process proceeds to step S102. In step S102, the inspection request information (bound inspection request information) associated with inspection 1 (104) is read from the inspection information storage unit 21, and the inspection request information is analyzed. The subsequent processes (the processes from step S103 to step S106) are the same as the flowchart in FIG. 6.

[0102] FIG. 17 is a diagram showing a display example of the inspection information association selection screen displayed on the display unit 2 in the fourth embodiment. Different from the inspection information association selection screen described in FIG. 5, since the held inspection 2 is restarted, the inspection to be the target of association is only inspection 2 in the inspection display area 106. Also, since the flowchart in FIG. 16 is executed before the display of the inspection information association selection screen (FIG. 17), in the display of the inspection request information list 120, only the inspection request information with high relevance has been extracted and filtered and displayed in the same manner as in FIG. 8 (inspection information association selection screen).

[0103] According to the fourth embodiment, when a plurality of tests (for example, Test 1 and Test 2) are tests that associate test request information at the same timing, the test request information for which the association has been performed and the information of the tests held can be collectively stored in the test information storage unit 21. When restarting the association for the held tests, since the relevance can be determined using the test request information for which the association has been performed, it is possible to prevent the association of test request information of different patients for each test, and as a result, reduce errors in the association target.

[0104] As described above, according to the techniques disclosed in the first to fourth embodiments, it is possible to efficiently associate tests with test request information. Since it is possible to extract highly relevant test request information from a plurality of test request information based on the test request information associated for the first time, it is possible to reduce the mistakes of the operator and perform the association efficiently.
