As shown in FIG. 3, the selection frequency table 131 includes at least items of combinations (assumed disease name-imaging site-imaging method), standard comments, and selection frequency. For example, as a combination, an assumed disease name "abdominal aortic flow", an imaging region "abdomen", and an imaging method "contrast" are recorded. The standard comment for the combination is "helical, simple 6 mm, MPR", and the number of selections is "210". As shown in FIG. 3, it is possible to associate a plurality of standard comments and selection counts with the same combination. The processing circuit 11 identifies a standard comment whose number of times of selection satisfies the extraction condition among standard comments associated with the combination acquired by the inspection order acquisition function 111 . For example, it is set as an extraction condition that it is within a predetermined rank such as within the top 10 ranks. A list of standard comments is stored in the master file 133 . Hereinafter, the standard comment master file will be referred to as standard comment master 133 . The standard comment master 133 is stored in the memory 13, for example.

In the selection frequency counting function 115 , the processing circuit 11 updates the selection frequency associated with the selected standard comment in the selection frequency table 131 each time a standard comment is selected by the standard comment selection function 113 .

In the fixed comment change function 116 , the processing circuit 11 changes the content of the fixed comment stored in the fixed comment master 133 in accordance with the user's instruction via the RIS terminal 20 . For example, when creating a new standard comment, the processing circuit 11 adds the standard comment to the standard comment master 133 .

In the display control function 117 , the processing circuit 11 generates various display data and transmits the generated display data to the RIS terminal 20 via the communication interface 15 . For example, the processing circuit 11 transmits data of an inspection instruction creation screen to the RIS terminal 20 . The processing circuit 11 also transmits data of the fixed comment specified by the fixed comment specifying function 112 to the RIS terminal 20 . Further, the processing circuit 11 may display various generated display data on a display (not shown) provided in the RIS server 10 .

The communication interface 15 is an interface for data communication with other computers. Specifically, the communication interface 15 performs various data communications with the RIS terminal 20, the HIS server of the HIS 3, the modality 5, and the like via the network. For example, the communication interface 15 receives an input device operation signal from the RIS terminal 20 . The received operation signal is supplied to the processing circuit 11 . The communication interface 15 also transmits display data generated by the display control function 117 to the RIS terminal 20 . The transmitted display data is displayed on the display 29 of the RIS terminal 20 .

For example, display 29 displays various display data received from RIS server 10 .

Details of the processing of the RIS 1 according to this embodiment will be described below.

FIG. 6 is a diagram showing a typical flow of inspection instruction input processing performed by the processing circuit 11 of the RIS server 10. As shown in FIG. It is assumed that the processing circuit 11 has obtained an examination order for a patient to be processed from the HIS 3 by the examination order obtaining function 111 before the start of step S1 in FIG. An examination order includes a combination of an assumed disease name, an imaging region, and an imaging method for a patient to be processed.

When the RIS terminal 20 issues an instruction to start the inspection instruction input process, the inspection instruction input process of FIG. 6 is started.

First, the processing circuit 11 causes the display control function 117 to display an examination instruction input screen on the display 29 of the RIS terminal 20 (step S1). The inspection instruction input screen is a display screen for inputting an inspection instruction.

FIG. 7 is a diagram showing an example of an inspection instruction input screen displayed in step S1. As shown in FIG. 7, the examination instruction input screen IS1 includes a patient basic information display area R1, a biochemical examination display area R2, a physical condition display area R3, a doctor display area R4, an examination order display area R5, and a referral comment display area R6. , each comment display area R7, an examination list display area R8, an examination list comment display area R9, a fixed comment list display area R10, and a detailed comment display area R11.

Basic patient information is displayed in the basic patient information display area R1. Information related to the biochemical test is displayed in the biochemical test display area R2. Information about the patient's physical condition is displayed in the physical condition display area R3. In the doctor display area R4, information regarding the requesting doctor for medical imaging of the patient is displayed. An inspection order is displayed in the inspection order display area R5. As an examination order, a type, an imaging region, an imaging method, and an assumed disease name are displayed. A transfer comment is displayed in the transfer comment display area R6. Each comment regarding the transfer is displayed in each comment display area R7. A list of past examinations of the patient is displayed in the examination list display area R8. In the examination list comment display area R9, comments regarding each examination in the examination list display area R8 are displayed. Information on biochemical tests, information on physical conditions, information on requesting doctors, orders, comments on referrals, comments on referrals, information on examinations and comments on each examination are supplied from HIS 3 together with basic patient information and/or examination orders. , or may be input by the user via the input interface 25 of the RIS terminal 20 .

A list of standard comments is displayed in the standard comment list display area R10. The standard comment list display area R10 includes an intermediate classification display area R10-1 and a standard comment display area R10-2. A middle classification list of standard comments is displayed in the middle classification display area R10-1. A standard comment display area R10-2 displays a list of standard comments belonging to the intermediate category selected in the intermediate category display area R10-1.

A detailed comment corresponding to the standard comment selected in the standard comment display area R10-2 is displayed in the detailed comment display area R11. The detailed comment may be a comment input by the user via the input interface 25 of the RIS terminal 20 .

As shown in FIG. 7, the inspection instruction input screen IS1 includes a selection candidate display button B1, a confirm button B2, and a close button B3. The selection candidate display button B1 is a GUI button for instructing display of selection candidates specified in step S2. The confirmation button B2 is a GUI button for instructing confirmation of the standard comment selected in step S4. The close button B3 is a GUI button for instructing to hide the inspection instruction input screen IS1 from the display 29. FIG.

When step S1 is performed, the processing circuit 11 executes the standard comment specifying function 112, and specifies selection candidates for standard comments from combinations of assumed disease names, imaging regions, and imaging methods relating to the patient to be processed (step S2). In step S<b>2 , the processing circuit 11 first executes the assumed disease name identification function 114 . In the assumed disease name specifying function 114 , the processing circuit 11 reads out the assumed disease name table 135 from the memory 13 . Then, the processing circuit 11 searches the assumed disease name table 135 using the character string of the assumed disease name related to the patient to be processed acquired by the examination order acquisition function 111 as a search key, and specifies the assumed disease name category associated with the character string. do. A test order is typically manually entered by a medical practitioner or the like. Therefore, even if an attempt is made to input the name of the same disease as a hypothetical disease name, there is a possibility that the name of the disease may not be correct depending on the doctor. By specifying the category of the assumed disease name using the assumed disease name table 135, it is possible to reduce the inconsistency (ambiguity) of notation for each user regarding the assumed disease name.

Next, the processing circuitry 11 executes the standard comment specifying function 112 . In the standard comment specification function 112 , the processing circuit 11 reads the selection frequency table 131 from the memory 13 . Then, the processing circuit 11 searches the selection frequency table 131 using a combination of the assumed disease name category, imaging region, and imaging method as a search key, and specifies a standard comment associated with the combination. Multiple standard comments are typically identified. Next, the processing circuit 11 identifies, as a selection candidate, a standard comment that satisfies an extraction condition regarding the number of times of selection from among the specified standard comments. For example, the extraction condition is that the number of selections is the top ten. In this case, the processing circuit 11 rearranges the number of times of selection of the plurality of specified standard comments in ascending or descending order, and specifies the standard comments with the top 10 number of times of selection as selection candidates.

Note that the extraction condition regarding the number of times of selection is not limited to the top ten. For example, the order may be any number, such as the top 5 or 20. Also, the extraction condition regarding the number of selections may be a threshold for the number of selections. That is, standard comments selected a predetermined number of times or more may be extracted as selection candidates. The predetermined number may be set to any number such as 10 or more.

Further, if there is no inconsistency in the notation of the assumed disease name included in the examination order acquired from the HIS 3 in step S2, the assumed disease name identification function 114 does not need to be executed in step S2. In this case, the selection frequency table 131 may be searched using a combination of the assumed disease name, imaging region, and imaging method included in the examination order as a search key.

When step S2 is performed, the processing circuit 11 executes the display control function 117 and displays on the display 29 a list of selection candidates specified in step S2. A list of selection candidates is displayed superimposed on the inspection instruction input screen displayed in step S1.

FIG. 8 is a diagram showing an inspection instruction input screen IS1 on which a list of selection candidates is superimposed. As shown in FIG. 8, a list of selection candidates (hereinafter referred to as a selection candidate list) R12 is superimposed on the inspection instruction input screen IS1. Specifically, the display window of the inspection instruction input screen IS1 is popped up on the inspection instruction input screen IS1. The selection candidate list R12 is displayed when the selection candidate display button B1 is pressed via the input interface 25 of the RIS terminal 20 as a trigger.

More specifically, when the selection candidate display button B1 is pressed, the processing circuit 11 generates a selection candidate list R12 regarding the selection candidates identified in step S2. The selection candidate list R12 displays, for example, the number of selections for each standard comment and the content of the standard comment. If the extraction condition is a predetermined high order, it is preferable that the selection candidate list R12 is displayed in order from the first place. In other words, the selection candidate list R12 in the case where the extraction condition is the predetermined upper ranking can also be referred to as a historical ranking of fixed comments related to inspection instructions. By referring to the selection candidate list R12, the user can know which standard comments are frequently selected for the combination of the patient's assumed disease name, imaging region, and imaging method.

The layout of the selection candidate list is not limited to that shown in FIG. For example, a selection candidate list R13 as shown in FIG. 9 may be displayed. The selection candidate list R13 displays the ranking of the number of selections for each standard comment. It should be noted that it is not necessary to display the order of standard comments below a predetermined order. In the selection candidate list R13, it is preferable that high-ranking standard comments are displayed in order from the top. The selection candidate list R13 may display information about biochemical tests and physical conditions.

When step S3 is performed, the processing circuit 11 executes the standard comment selection function 113 to select one standard comment from the selection candidate list R12 (step S4). For example, the user designates any standard comment from the selection candidate list R12 via the input interface 25 of the RIS terminal 20. FIG. This allows the user to specify a standard comment regarding the patient from standard comments that satisfy the extraction conditions. For example, if the extraction condition is a predetermined high order, it is possible to designate frequently selected standard comments for the combination of the patient's assumed disease name, imaging region, and imaging method. The processing circuit 11 selects the specified standard comment.

When step S4 is performed, the processing circuit 11 executes the display control function 117 and inputs a detailed comment corresponding to the standard comment selected in step S4 to the inspection instruction input screen. Specifically, when the standard comment is selected in step S4, the user presses the confirmation button B2 via the input interface 25. FIG. Triggered by pressing of the confirm button B2, the processing circuit 11 inputs the same text as the selected standard comment into the detailed comment display area R11 of the inspection instruction input screen IS1. When the user inputs an additional text regarding the detailed comment via the input interface 25 of the RIS terminal 20, the processing circuit 11 inputs the input text to the detailed comment display area R11. The detailed comment input to the detailed comment display area R11 is used as an inspection instruction.

It should be noted that the list of selection candidates displayed in step S3 may not include an appropriate standard comment. In this case, the user may specify a standard comment from the standard comment list display area R10 via the input interface 25. FIG. In this case, the processing circuit 11 inputs a sentence corresponding to the designated standard comment to the detailed comment display area R11. Also, if the standard comment list display area R10 does not include an appropriate standard comment, the user may directly input the comment in the detailed comment display area R11 via the input interface 25. FIG.

This completes the description of the inspection instruction input process.

According to the inspection instruction input process described above, it is possible to present the user with a fixed comment that satisfies the extraction condition, so that it is possible to reduce variations in inspection instructions for similar inspection orders. Further, by selecting the presented standard comment, it is possible to input an inspection instruction as a detailed comment, so it is possible to improve the efficiency of inputting an inspection instruction.

In the above description, it is assumed that the selection candidate list R12 is superimposed and displayed on the examination instruction input screen IS1 when the selection candidate display button B1 is pressed. However, this embodiment is not limited to this. For example, it is preferable that the selection candidate list R12 is displayed in the inspection instruction input screen IS1. That is, as shown in FIG. 10, a selection candidate list R12 is embedded in the inspection instruction input screen IS2. In this case, the selection candidate display button B1 need not be provided on the examination instruction input screen IS2. For example, when a standard comment is specified in step S2, the processing circuit 11 automatically displays a selection candidate list R12 corresponding to the specified standard comment in the corresponding area of the inspection instruction input screen IS2.

Various modifications are possible for the examination instruction input screen according to the present embodiment. Various modifications will be described below.

As described above, the processing circuit 11 can change the content of the standard comment master 133 by the standard comment change function 116 . For example, assume that the fixed comment "helical, simple 6 mm, MPR" in the fixed comment master 133 shown in FIG. A record is added to the selection count table 131 for the added standard comment “simple 6 mm, MPR”. The number-of-selections table 131 associates the fixed comment "Helical, simple 6 mm, MPR" before change with the fixed comment "Simple 6 mm, MPR" after change. Now, as in the above example, the standard comment "Helical, simple 6 mm, MPR" has been selected 210 times, satisfying the extraction conditions, and the standard comment "Simple 6 mm, MPR" has been selected 3 times, not satisfying the extraction conditions. shall be In this case, as shown in FIG. 11, the processing circuit 11 displays a related display button B4 in the display field R14 of the standard comment "helical, simple 6 mm, MPR" included in the selection candidate list R12. Specifically, when there is a fixed comment after change associated with the fixed comment before change included in the selection candidate list R12 in the selection frequency table 131, the processing circuit 11 displays the fixed comment before change. A related display button B4 is displayed in the column.

When the related display button B4 is pressed via the input interface 25 of the RIS terminal 20, as shown in FIG. . The post-change standard comment display field R15 is displayed so that the pre-change standard comment and the post-change standard comment are related to each other. For example, as shown in FIG. 12, the standard comment display field R15 after change is preferably displayed adjacent to the standard comment display field R14 before change. A close button B5 is displayed in the display field R15 for the modified standard comment. When the close button B5 is pressed via the input interface 25 of the RIS terminal 20, the processing circuit 11 closes the display field R15 for the changed standard comment. When the post-change standard comment display field R15 is closed, the related display button B4 is displayed again in the pre-change standard comment display field R14, as shown in FIG.

In this way, when a standard comment included in the standard comment master 133 is changed and the standard comment before the change is displayed in the selection candidate list, the standard comment after the change does not satisfy the extraction conditions. Also, it is preferable that the fixed comment after the change is displayed in addition to the fixed comment before the change. According to this display form, the user is prompted to select the new standard comment when the standard comment before the change was the mainstream, but the new standard comment after the change matches the recent medical trend. becomes possible.

In the above example, the display items of the selection candidate list are the standard comment and the number of selections. However, this embodiment is not limited to this. For example, the display items of the selection candidate list may include the name of a doctor who has selected the standard comment in the past, in addition to the standard comment and the number of selections. In this case, as shown in FIG. 13, the selection frequency table 131 has doctor items in addition to combinations (assumed disease name, imaging site and imaging method), standard comments, and selection frequency. The name of a doctor who has selected the standard comment in the past is registered in the doctor's item. All doctors who selected the standard comment may be registered, or the most recent doctor who selected the standard comment may be registered.

FIG. 14 is a diagram showing a display example of the selection candidate list R14 including the standard comments shown in FIG. As shown in FIG. 14, in the display column of each standard comment included in the selection candidate list R16, the doctor's name is displayed in addition to the number of selections and the standard comment. In the selection frequency table 131, all doctors associated with the standard comment may be displayed, the most recent doctor who selected the standard comment may be displayed, or only doctors who selected the standard comment may be displayed. The doctor who hired the most may be displayed, or other doctors may be displayed. By displaying the doctor's name for each standard comment, it is possible to provide the user with useful information for selecting an appropriate standard comment.

In the above example, the selection frequency table 131 associates a standard comment with each combination of assumed disease name, imaging region, and imaging method. However, this embodiment is not limited to this. The constituent elements of the combination may include biochemical test items and physical measurement items in addition to the assumed disease name, imaging region and imaging method. Examples of biochemical test items include Cr, BUN, and eGFR. Body measurement items include, for example, weight, height, and chest circumference. By specifying and displaying standardized comments in consideration of factors other than the assumed disease name, imaging site, and imaging method, it is possible to select a more appropriate standardized comment for the patient.

Next, the processing of the selection number counting function 115 will be described. In the selection frequency counting function 115, the processing circuit 11 updates the selection frequency of the selected standard comment when a standard comment is selected from the selection candidate list displayed in step S3. Specifically, the processing circuit 11 detects that a standard comment is specified via the input interface 25 and that the confirmation button B2 included in the inspection instruction input screen IS1 or the like is pressed, and associates the standard comment with the standard comment in the selection frequency table 131.
