  The present invention relates to a medical image diagnostic system and a medical image diagnostic method, and more specifically, can perform image diagnosis by efficiently interpreting a medical diagnostic image such as a large amount of radiographic images obtained by a group medical examination and the like, and The present invention relates to a medical image diagnostic system and a medical image diagnostic method capable of easily inputting a diagnosis result and further enabling multiple interpretation by a plurality of interpretation doctors and thus multiple diagnosis.

Conventionally, diagnosis of medical diagnostic images such as radiographic images has been performed by radiological doctors, etc., by attaching an X-ray film to a shaucusten, etc., observing and interpreting transmitted images, but in recent years, radiographic images have been accumulated. Using a stimulable phosphor sheet with a stimulable phosphor layer that exhibits stimulable luminescence corresponding to the radiation image accumulated with the irradiation of excitation light, a digital radiographic image is obtained, and an interpreting doctor or radiographer Examiners such as these are displayed on a display device such as a high-luminance CRT display device or an LCD display device, and a digital radiographic image diagnostic system that observes and interprets the displayed image has come to be used.
The digital radiographic image used in such an image diagnostic system is acquired using an accumulative phosphor sheet, X-ray film is acquired by an image reading device such as a scanner, or radiation using a radiation conversion panel. Taking a picture and acquiring a digital radiation image directly is performed.

The digital radiographic image acquired in this way is associated with an image identification code (ID) in the diagnostic imaging system, or information on the patient about a patient in a hospital, a medical examination examinee, etc. The image information is stored in an image storage device such as an image server in association with examination information related to the examination received by the examinee, including imaging information relating to imaging such as an imaging part, an imaging date, and an imaging device (modality).
In an image diagnosis system, at the time of image diagnosis, a search (as a search key) is performed on an image storage device based on an identifier of an examination unit, and an image required for image diagnosis or a specific inspection target image is extracted, and the image storage device The corresponding examination object image is read out from the image, displayed on the image display device, and the displayed radiographic image is observed by an interpreting doctor to perform image interpretation and image diagnosis, and a diagnosis result (report). , Recording on a recording sheet, input to a diagnostic result storage device, and output from an output device (printer).

However, it is necessary for the user such as an interpreting physician to intentionally specify a method for extracting or specific inspection target image necessary for image diagnosis, a method for reading and displaying the inspection target image, and the like. Extracting images, reading and displaying images to be inspected, and recording and inputting diagnostic results are tasks that require carefulness, of course, accuracy, and are laborious and time-consuming for users such as interpreting physicians. Therefore, it takes time to interpret and diagnose an image.
In particular, it takes a very long time to perform a series of operations such as retrieval, extraction, display, interpretation, and input of diagnosis results (reports) for examination images to be interpreted from a large number of medical images obtained in group examinations or large hospitals. Is needed.
For this reason, in conventional diagnostic imaging systems, proposals have been made to improve efficiency, reduce workload, and reduce labor in various operations within a series of diagnostic imaging operations (Patent Document 1, Patent Document 2 and Patents). Reference 3).

By the way, in the medical radiological image interpretation apparatus disclosed in Patent Document 1, it is possible to easily extract and display a list of secondary interpretation target images that require close examination after the primary interpretation. Interpretation efficiency can be improved. The image storage means is dedicated to medical radiographic image information and stores only medical radiographic image information and its image identification information. The subject information storage means stores information on the patient and the examinee, image identification, and the like. Since only subject information including imaging information such as information, imaging date and imaging device is stored, the subject information storage means searches for the interpretation target image using the imaging date etc. as a search condition, and It is configured to acquire image identification information and sequentially transfer it to the image display means so that only a desired image can be easily extracted and diagnosed from a large number of images, and past diagnosis results can be easily searched. be able to.
However, there is no disclosure at all of a specific method for sequentially transferring the image to be interpreted that has been retrieved and extracted to the image display means. Since a conventional image readout and transfer method in which a target image is selected and then transferred from the image storage means to the image display means is merely performed, a medical diagnostic image, particularly a large-size radiation image such as a chest In such cases, there is a problem that it takes time to transfer and the efficiency of primary interpretation is not sufficient.

In addition, although the diagnosis results by a plurality of doctors can be input by a plurality of diagnosis result storage means, basically only one apparatus diagnoses the same image, and a plurality of doctors There is a problem that the apparatus configuration is not capable of simultaneous multiple interpretation, and is not an apparatus configuration that diagnoses independently from the diagnosis results of other doctors.
Furthermore, since the image storage means is dedicated to medical radiographic image information, it is efficient when interpreting a large number of medical diagnostic images at once, such as in a group examination, but interprets one or a small amount of medical diagnostic images. Even in this case, the image storage means is directly searched, the inspection target image is read from the image storage means and cannot be transferred to the image display means, the subject information storage means is searched, and the image identification information of the inspection target image is obtained. There is a problem that it is necessary to read the image to be inspected from the image storage means using the image identification information and transfer it to the image display means.

  In addition, the medical image management system disclosed in Patent Document 2 prevents incidental information input errors and improves incidental information input efficiency and report creation work efficiency. Since the associated information is stored in association with each other, the amount of image information (image data) is large. Therefore, it takes time to search for a medical image and its accompanying information, and medical diagnosis that requires image diagnosis (interpretation) is required. It is not easy to display a list of accompanying information about an image, and the medical medical image and the accompanying information are displayed in different setting areas on the same display screen. In addition, a medical diagnostic image is efficiently displayed. There was a problem that we couldn't.

  In addition, the report creation support system disclosed in Patent Document 3 is also variously efficient in inputting diagnosis results, as in the case of the medical image management system disclosed in Patent Document 2, thereby improving the efficiency of report creation and reducing the work load. In order to reduce the workload of creating a high-quality report with unified expression and the like, the image information management unit, as in Patent Document 2, uses image information and inspection information. In addition, since the result information is also managed in association with each other, the amount of information (data) is large. Therefore, it takes time to process, and it is not easy to display a list of images of the report input inspection (interpretation inspection). There was a problem.

  An object of the present invention is to solve the above-mentioned problems based on the prior art, automatically display a list of inspection information to be interpreted in advance, and sequentially and easily start from the top of the inspection information displayed or a specified line. With a simple key operation, it is possible to display medical diagnosis images to be examined continuously for high-speed reading, and to input diagnosis results as reports, without burdening users such as radiological doctors.

As described above, the image viewer 16 searches and extracts a plurality of pieces of examination information corresponding to a plurality of medical diagnostic images that are continuously read from the image management server 14, The medical examination image displayed on the display 26 as a list, corresponding to predetermined examination information on the first line or selected line, is read out from the image server 12 as the examination object image, displayed on the display 24, and displayed. Based on the image, an interpretation by an examiner such as an interpreting doctor, the diagnosis result is input as a report by the input device 28, and the report generated by the input device 28 is input to end the report creation. The next image to be inspected corresponding to the inspection information on the next line is automatically and rapidly displayed on the display 24 to enable continuous interpretation. A.

The display 24 corresponds to predetermined examination information among a plurality of medical diagnosis images stored in the image server 12 and displays an examination target image to be subjected to image diagnosis, such as an examiner such as an interpreting doctor or an interpretation engineer (hereinafter referred to as an examination doctor). In the example shown in the figure, it is composed of two image display displays 24a and 24b.
In the present embodiment, the display 24 is shown as having a configuration having two screens as described above. However, the present invention is not limited to this, and the display 24 has one screen or two or more screens. It may be a configuration.
The image display 24 used in the present invention may be any display as long as it can diagnose a medical image, and may be a conventionally known display that has been used for diagnosis of a medical image. All can be applied, and the display method is not particularly limited, and any display method may be used. Examples of the display method include a CRT display device, an LCD display device, and a plasma display device. Note that a high-luminance display is preferably used as the image display 24 as a medical image, particularly when a radiation transmission image is diagnosed, but the present invention is not limited to this.
Further, the number of pixels of the displays 24a and 24b is not particularly limited as long as image diagnosis is possible. In addition, as the displays 24a and 24b in the illustrated example, two vertical displays can be used.
The displays 24a and 24b display medical diagnosis images (inspection target images) to be interpreted on the entire screen on both sides, but may display different images for each side (see FIG. 1). The same image may be displayed on both sides (see FIG. 5), or one image may be displayed across the two sides. Furthermore, when confirming the diagnosis result input at the time of report creation, it may be used as a result confirmation screen (see FIG. 6).

Here, a specific example of an image display screen displaying the same image on both sides is shown in FIG.
On the image display screen shown in FIG. 5, the same chest radiographic image is displayed on both sides except for the upper operation menu part, and the upper operation menu part shows the examinee of the display image for confirmation. Number of examinations such as name, date of birth, age, gender, etc., number of examinations held on the interpretation list, number of confirmed examinations that registered the diagnosis results as "normal" and "with findings", and the number of overall examinations It is displayed.
The operation menu section includes three buttons, a “normal” button for selecting (clicking) when the diagnosis result is normal, a “hold” button for holding the diagnosis result, and a “finding” button for displaying the finding input screen. A diagnostic registration button is provided. Here, when the “Normal” button and the “Hold” button are clicked, a result confirmation screen (see FIG. 6) is displayed. The inspection target image is immediately switched and displayed. Note that when the “finding” button is clicked, as will be described later, the display 26 is further provided with a “previous” button and a “next” button in the operation menu section, and the result is displayed on the interpretation list without inputting the interpretation result. The images of the previous inspection and the next inspection displayed on the screen are displayed. Further, when the display image has already been interpreted, the previous interpretation information including the finding is displayed.

Next, FIG. 6 shows a specific example of the result confirmation screen for confirming the interpretation result of the image displayed on the image display screen of the display 24.
The result confirmation screen shown in FIG. 6 is displayed so as to be superimposed on the display image of the image display screen of the display 24, and is displayed when the diagnosis results of “normal”, “hold” and “finding” are input. This is a confirmation screen and can be hidden by setting.
First, on the result confirmation screen, the name of the examinee who inputs the diagnosis (interpretation) result and the contents of the diagnosis result are displayed. The result confirmation screen further includes a “Yes” button and a “No” button. The “Yes” button is a key for confirming the input of the diagnosis result and automatically displaying the next inspection target image on the display 24. The “No” button is for keeping the current image to be inspected on the display 24 without inputting the diagnosis result.

Further, the result confirmation screen is provided with a check box for setting the non-display of the result confirmation screen. If this check box is checked, the confirmation message "Diagnosis confirmation dialog box will not be displayed. Image display will be performed automatically after diagnosis input. Please perform the operation after confirming the image display." The screen is displayed. Thereafter, when the diagnosis result is input, this screen is not displayed, the diagnosis result is confirmed, and the next inspection target image is automatically displayed on the display 24 immediately. By setting the result confirmation screen to non-display, when a diagnosis result is input, it is immediately confirmed and the display 24 is automatically switched to the next inspection target image in the standby state and displayed. Therefore, display switching can be performed faster.
The result confirmation screen may be displayed on the image display screen of the display 24 by switching to the display image, or may be displayed on the information display screen of the display 24.

The display 26 retrieves a plurality of examination information corresponding to a plurality of medical diagnosis images to be diagnosed from among a plurality of examination information stored in the image management server 14, that is, continuously read and displays them as a list. Then, the examination information to be interpreted as necessary is selected, and the interpretation doctor observes and interprets the examination target image displayed on the display 24 and inputs the interpretation result, that is, the diagnosis result. The result display / input field or screen is displayed in correspondence with predetermined examination information, and the interpretation doctor displays the diagnosis result input on the diagnosis result display / input field or screen by the input device 28. It functions as information display means of the invention.
The information display 26 used in the present invention is not particularly limited as long as the inspection information is easy to read and discriminate as text (character strings) or a list. Any conventional display for displaying characters used from the above can be applied, and the display method is not particularly limited, and any display method may be used. Examples thereof include a device, an LCD display device, and a plasma display device. That is, the display 26 may be used as a display of a normal PC (personal computer), WS (workstation), terminal, or the like. In the illustrated example, for example, a 15-inch color LCD display device or A 17 inch color LCD display can be used.

In the illustrated example, the display 26 is used exclusively for information display. However, the present invention is not limited to this, and one of the two displays 24a and 24b is used for information without using the information display dedicated display. It may be used for display.
In addition, the display screen of the display 26 includes a list display screen (interpretation list screen) of diagnosis target examination information and a list display screen (interpretation list screen) having an interpretation column (diagnosis result display / input column) (see FIG. 4), a finding (diagnosis result) input screen (see FIG. 7) is displayed, and a startup screen of the image viewer 16, a screening course selection screen, and a simultaneous interpretation by an interpreting doctor and an engineer will be described later. An interpretation field selection screen (see FIG. 3), a result confirmation screen (see FIG. 6), or the like may be displayed depending on the situation.

Here, FIG. 4 shows a specific example of a list display screen (interpretation list screen) having a plurality of interpretation fields (diagnosis result display / input fields).
The interpretation list screen shown in FIG. 4 is a screen that is displayed on the display 26 while the examination target image displayed on the display 24 is being interpreted. The name of the examination course and the number of examinations are displayed, and below that, a list of examination information (examination list) having two examination fields 1 and 2 corresponding to this is displayed. In the lowermost display column, details of the interpretation results by the interpretation doctors in the interpretation columns 1 and 2 for the examination target image being interpreted are displayed. Of course, the interpretation result of the examination (shaded line in the figure) where the cursor is on the list (interpretation list) is displayed.

In the operation menu section on the upper side of the interpretation list screen, an interpretation start button for displaying the examination target image corresponding to the examination on which the cursor is placed on the list on the display 24, and an “interpretation interpretation” button for closing the interpretation list screen , "Pending list" button to display only the examinations with interpretation results "Pending", "List of observations" button to display only examinations with interpretation results "Presentation", "Update list" button to update examination information and A “result output” button for displaying an output result screen is provided.
In the central list (interpretation list) of the interpretation list screen, the examiner ID, the name of the examinee, the gender, and the date of birth are displayed for each examination as the examinee information. The medical name and diagnosis results (“normal”, “hold”, “with findings”) are displayed for each examination.
In the interpretation result display field at the bottom of the interpretation list screen, the list (interpretation list) is entered in the interpretation input screen, which will be described later, by the interpretation doctors in interpretation fields 1 and 2, and registered abnormal parts and findings. As a result of interpretation, including diagnosis, determination and comments, the information of the examinee, the name of the examinee, the sex, and the date of birth are displayed for each examination, and in the interpretation fields 1 and 2, the interpretation doctor name and diagnosis result are displayed. (“Normal”, “Pending”, “With findings”) is displayed for each examination. Here, all the interpretation results in the interpretation fields 1 and 2 are displayed, but in the case of blind interpretation, only the logged-in interpretation field is displayed, and the results in the other interpretation fields are not displayed.

  The input device 28 is used to input a diagnosis result obtained by the interpretation of the image interpretation doctor displayed on the display 24. The input device 28 includes a keyboard 28a and a mouse 28b, and functions as a diagnostic result input unit of the present invention. is there. The keyboard 28a and mouse 28b used in the present invention are not particularly limited, and those used for ordinary PCs, WSs, terminals, and the like can be used. Note that the keyboard 28a and the mouse 28b not only input an interpretation result (diagnosis result) but also activate the image viewer 16, select examination information in a list (interpretation list), and display the two displays 24a and 24a on the display 24. Various information can be input on each display screen of the display 24b and the display 26, such as movement of a cursor or pointer over each screen, selection of an option on the display GUI, and the like.

The control unit 30 is the most characteristic part of the image viewer 16 that is a characteristic part of the present invention, and each component of the image diagnostic system is implemented so that the image diagnostic method of the present invention is performed. And has the function of the control means of the present invention. As described above, the control unit 30 reads from the image server 12 the inspection target image corresponding to the predetermined inspection information in the first row or selected row of the list displayed on the display 26 and causes the display 24 to display the image. At the same time, the next medical diagnostic image to be subjected to the image diagnosis corresponding to the next examination information in the next row below the predetermined examination information in the list is read from the image server 12 and is displayed on the display 24 as the examination target image. Before displaying, at least a part of the next medical diagnostic image is read out from the image server 12 and temporarily stored, and the input of the diagnostic result by the input device 28 is completed ("Normal" in FIG. 5). Button, the “Yes” result input button in FIG. 6 and the “Register finding” button in FIG. 7), the image to be inspected displayed on the display 24 is read out first. If there is a remaining image that has not been read ahead of the next medical diagnostic image, the remaining image is read from the image server 12 and displayed next. Next, the medical diagnostic image is completely displayed, or after the remaining image is read from the image server 12, the image to be inspected displayed on the display 24 is read first. Control is performed so as to switch to and display the medical diagnostic image.

The control unit 30 is connected to the image server 12 and the image management server 14 via a network (or communication means), and controls image display control means 52 that controls image display on the two displays 24a and 24b of the display 24. A list of examination information of examinations to be interpreted from the image management server 14 is created and displayed on the display 26 to provide an interpretation workflow and input of interpretation results (diagnosis results) (simple findings function) And image management server control means 54 for performing the above. In addition, the control unit 30 is also connected to the two displays 24a and 24b of the display 24, the display 26, and the keyboard 28a and the mouse 28b of the input device 28, and controls each element of the image viewer 16. It also has a function.
The control unit 30 has the above-described various functions as the image viewer 16, controls the display of diagnostic images on the displays 24a and 24b, and the display of various information on the display 26, and performs various methods for carrying out the method of the present invention. Any device can be used as long as it has the ability and function to perform the information processing, and any device that can be used as a main body of a conventionally known PC, WS, terminal, or the like is applicable. .

Here, the image display control means 52 is connected to the image transfer means 44 of the image server 12 via a communication means. The image display control means 52 is constituted by image viewer software, is called by web inquiry from the image management server control means 54, receives predetermined inspection information to be inspected from the image management server control means 54, and based on this inspection information. Then, the image transfer unit 44 of the image server 12 is accessed via the Internet (HTTP), and a medical diagnostic image corresponding to the examination information is read from the image storage 42 and displayed on the display 24.
On the other hand, the image management server control means 54 is connected to the DB 50 of the image management server 14 via a network. The image management server control means 54 is configured as client software for the image management server 14, accesses the DB 50 of the image management server 14, and uses examination information (patient information, examinee information, imaging information) stored in the DB 50. All examination information having a predetermined identifier, for example, examination information corresponding to the designated examination course and examination date is read out, a list of examination information to be interpreted (interpretation work list) is created, and displayed on the display 26 as a list To do. Further, when the examination target image is displayed on the display 24 under the control of the image display control means 52, the image management server control means 54 displays an input screen (input field) for the diagnosis result (findings) on the display 26. Then, the interpretation doctor prompts the user to input an interpretation result. When the interpretation result is input, the DB 50 of the image management server 14 is accessed, and the input diagnosis result is stored in the DB 50 in association with the examination information.

  The control unit 30 and the image viewer 16 are basically configured as described above. Hereinafter, the operation of the control unit 30 and the medical image diagnostic system 10 and the medical image diagnostic method of the present invention will be described based on the embodiments. Will be described more specifically.

Example 1
First, a continuous sequential display method of medical diagnostic images on the display 24 of the image viewer 16 will be described.
The control unit 30 (image management server control means 54) of the image viewer 16 searches the DB 50 of the image management server 14 using a predetermined or unique identifier included in the examination information as a key, and classifies it into preset categories. The corresponding examination (examination information to be subjected to image diagnosis) is called up in the diagnosed unit and displayed in a list on the display 26 of the image viewer 16.
In this case, the image management server control means 54 checks the inspection in which the first digit is 1 among the 4 digits of the inspection ID from the inspection information stored in the inspection storage table of the DB 50 of the image management server 14 shown in Table 1. Only examinations with IDs (information: shading process) are extracted and displayed on the display 26 as a list. Table 2 shows the extraction results of the corresponding examination (information) extracted in this way.

[Table 1]
<Inspection storage table>
Inspection ID: 1001, 1002, 1003 applicable

[Table 2]
<List display>

  Next, the control unit 30 causes the display 24 to display an image of the inspection target image corresponding to the first row or the designated (selected) row by the interpretation doctor among the examinations (information) displayed as a list in Table 2. As shown in Table 3, the image management server control unit 54 selects the first row (examination ID: 1001) of the examinations (information) displayed as a list, and inquires the image display control unit 52 about the examination ID. The image display control means 52 reads the inspection object image from the image storage 42 via the image transfer means 44 of the image server 12 using the inspection ID as a key, and displays the image on the display 24.

[Table 3]
<Image display> Inspection image of inspection ID: 1001 is displayed.

Next, the image to be examined displayed on the display 24 is read by the interpretation doctor, and the interpretation result is input to a diagnostic result input screen displayed on the display 26 (see the observation input screen FIG. 7 described later). Is input using.
During the interpretation of the examination target image by the interpretation doctor, the control unit 30 transfers the image of the image server 12 using the examination ID (1002) of the examination information of the next line in the list (see FIG. 4) as a key. Reading of the next examination target image from the image storage 42 is started via the means 44, and at least a part of the next medical diagnostic image is read first from the image server 12 and temporarily held.

  After the interpretation result is input by the interpreting doctor, the examination target image corresponding to the examination of the next row in the list (list) is automatically displayed on the display 24. When an input doctor completes input of an interpretation result (see “Normal” button in FIG. 5, “Yes” result input button in FIG. 6 and “Find findings” button in FIG. 7) from the input device 28, the input completion is switched. Thus, the display on the display 26 is switched as shown in Table 3 to Table 4, and the display on the display 24 is automatically inspected for the first row of the list displayed on the display 26 (inspection ID: 1001) to the inspection target image of the inspection (inspection ID: 1002) in the next lower row of the list.

[Table 4]
<Display of next inspection image> Display inspection image of inspection ID: 1002

Note that at least a part of the inspection target image with the inspection ID (1002) is read first. Here, when all the data has been read, the display is switched immediately and displayed completely. However, when the pre-reading is not completed, the display switching on the display 24 is slightly delayed to complete the pre-reading. This may be performed after the reading of the remaining images that have not been completed, or the display 24 may be switched while the remaining images are being read. In any case, after inputting the interpretation result, the control unit 30 obtains the inspection ID (1002) of the next line in the list, and uses the obtained inspection ID to cause the image transfer unit 44 of the image server 12 to operate. The automatic display of the inspection object image can be greatly speeded up as compared with the case where the image storage 42 is searched for, the corresponding inspection object image is read out and displayed on the display 24.
In this way, continuous sequential display of inspection target images on the display 24 of the image viewer 16 can be performed at high speed.

(Example 2)
Next, a multiple interpretation method by a plurality of interpretation doctors will be described.
In the following, as a specific example, double simultaneous interpretation by two interpreting doctors will be described as a representative example. However, the present invention can of course perform multiple simultaneous interpretation by two or more interpreting doctors.
In addition, when performing multiple simultaneous interpretations by two or more interpreting doctors, it is preferable that each interpreting doctor is provided with an image viewer 16, but the control unit 30 may include each of the plurality of image viewers 16. If the elements can be controlled, they may be common, and if the number of persons is small, the display 24 for displaying the inspection target image may be shared by several persons, or multiplexed while referring to each other's interpretation results. In the case of simultaneous interpretation, the display 26 may be shared by several persons as long as the number of persons is small. In the following description, it is assumed that each image interpretation doctor is provided with an image viewer 16.
If it is not simultaneous interpretation, even if it is multiple interpretation, it is sufficient if a single image viewer 16 is provided. However, in this case as well, a plurality of image viewers 16 may be used. It is good also as a structure similar to the case.

In the present invention, one examination, that is, an examination target image can be simultaneously interpreted by two or more interpreting doctors. Therefore, in order to hold a plurality of interpretation results in the DB 50 of the image management server 14 for one examination, the examination ID of the examination storage table shown in the following Table 5 is used as a key and the following Table 5 shows By storing a plurality of results in the result storage table, multiple interpretation by a plurality of interpretation doctors can be realized. As shown in Table 5, the number stored in the interpretation column of the result storage table of the DB 50 is a key for determining the number of interpretation results.
In this way, it is possible to display a list of a plurality of interpretation results together with examination information.

＜結果格納テーブル＞

[Table 5]
<Inspection storage table>

<Result storage table>

For this reason, after starting the interpretation, a GUI for selecting which interpretation field to interpret is present on the display screen of the display 26 as an interpretation field selection screen.
An example of this interpretation field selection screen is shown in FIG. In the example shown in FIG. 3, it is configured so that two radiographers can interpret simultaneously. As a result, four interpretation modes of a single interpretation mode, a double open interpretation mode, a double check interpretation mode, and a double blind interpretation mode are possible. By selecting either one of the interpretation fields in accordance with the interpretation workflow of the medical image diagnostic system on this interpretation field selection screen, individual interpretation modes can be selected.

The main functions of the interpretation field selection screen will be briefly described.
First, the “inspection number display” field is provided for each of the interpretation fields 1 and 2, and the interpretation fields 1 and 2 display the number of uninterpreted examinations and the total number of examinations for the designated course and examination date.
The “history display of already-reading doctor names” is provided for each of the interpretation fields 1 and 2, is in a grid format, and displays the names of the interpreting doctors who have performed interpretation in the interpretation fields 1 and 2. A plurality of interpretation doctor names can be displayed, but when all the interpretation doctors cannot be displayed on the screen, a scroll bar is displayed and can be confirmed by scrolling.
In the “interpretation enabled / disabled confirmation message”, a message indicating whether or not the interpretation fields 1 and 2 can be selected by checking the current interpretation status in the interpretation fields 1 and 2 is displayed.
The “interpretation list display” button is enabled when it is in an interpretable state, and when clicked, the screen shifts to an interpretation list screen.
In the case of single interpretation, only interpretation field 1 is displayed.

First, as a first mode of multiple interpretation, there is a multiple open interpretation mode in which diagnosis results by two or more interpretation doctors are displayed in a list on the display 26 and can be interpreted while referring to the other interpretation result. it can. The inspection information and result information are read from the inspection and result storage table as shown in Table 5 in the DB 50 of the image management server 14 and displayed in a list on the display 26 as shown in Table 6 and selected inspection target images. Is read from the image server 12 and displayed on the display 24.
In Table 6, there are only two interpretation fields, but if there are n interpretation fields, the interpretation results by a plurality of interpretation doctors are displayed in a list in the interpretation fields 1, 2,..., N. Can do.
As shown in Table 6, the examination target image is displayed on the display 24 while displaying a list having a plurality of interpretation fields on the display 26, so that two interpretation doctors (teacher A and teacher B). Can be interpreted simultaneously while referring to each other's results. For this reason, the interpretation results of the other interpreting doctor or the interpreting doctor who performs the later interpretation may be affected by the interpretation results of the interpreting doctor who performs the previous interpretation. In general, it is possible to improve the accuracy of interpretation, especially when the interpretation results of the two people are different, the interpreting doctors who interpret each other or later can perform particularly precise interpretation. Therefore, the accuracy of interpretation can be increased.

[Table 6]
<List display>

Next, as a second mode of multiple interpretation, among the interpretation results by two or more interpretation doctors, only the interpretation results of the user, that is, only the interpretation column, are displayed on the list displayed on the display 26. The multiple blind interpretation mode that can prevent the interpretation result (interpretation field) from being displayed. In this mode, after the interpretation is completed, the interpretation results of each other can be output as a hard copy (paper print) from the printer 22, and the interpretation results of each other can be displayed on the display 26 as a list. In this way, it is possible to check the diagnosis result of the list printed out and the diagnosis result of the list displayed on the display 26.
Examination information and result information are read out from the examination and result storage table as shown in Table 5 in the DB 50 of the image management server 14, and as shown in Table 7 (No. 1 and No. 2), the result of interpretation on the display 26 is displayed. Only the selected image to be inspected is read from the image server 12 and displayed on the display 24. That is, the interpretation results other than the interpretation field 1 are not displayed for the teacher A who selects the interpretation field 1, and the interpretation results other than the interpretation field 2 are not displayed for the teacher B who selects the interpretation field 2. .

As shown in Table 7 (No. 3), the interpretation of interpretation fields 1 and 2 (interpretation fields 1, 2,..., N for multiple interpretation) has been completed, and all the interpretation results have been input. In this case, all the interpretation results stored in the interpretation fields 1 and 2 (interpretation fields 1, 2,..., N) are displayed as a list on the display 26.
Thus, during the interpretation, the other interpretation result is not displayed in the list display of the display 26, but only the own result is displayed. After the interpretation is completed, all the results are displayed, and the results of each other can be confirmed.
For this reason, it is possible to independently interpret each other without being influenced by the interpretation results of the other interpreting physician, and after the interpretation is completed, all the results can be displayed and the results of each other can be confirmed. Thus, when the interpretation results are different from each other, specially precise re-interpretation can be performed on each other, so that the accuracy of interpretation can be improved.
In the multiple blind interpretation mode, multiple simultaneous interpretation may be performed, but multiple simultaneous interpretation may not be performed.

As described above, in the present invention, the multiple interpretation has a multiple open interpretation mode (first mode) and a multiple blind interpretation mode (second mode), and these modes are switched to appropriately perform multiple interpretation. It can be carried out. In the present invention, in addition to these modes, as a third mode of multiple interpretation, among the interpretation results obtained by two or more interpretation doctors, the previous interpretation result is confirmed and checked while being checked. Interpretation can be performed by switching between four modes: a multiple check interpretation mode in which an interpretation result can be input and a single interpretation mode in which interpretation is performed by one person as the fourth mode.
Here, the multiple check interpretation mode is, for example, an interpretation by a skilled interpreting doctor by an expert interpreting while checking an interpretation result performed by an unskilled interpreting doctor or a beginner, or vice versa. An interpreting doctor who is not an expert or a beginner interprets an image while observing the result, so that an interpreting doctor who is not an expert or a beginner can be trained.

(Example 3)
Next, a method for simplifying the input of findings as diagnosis results will be described.
In the following, as a specific example, a simple input method for abnormal sites in the chest, stomach, and mammo in the input of findings will be described, but the present invention is not limited to these, and other test sites and tests such as brain and chest CT Of course, the method image can be easily input in the same manner.
First, FIG. 7 shows an example of the finding input screen. During interpretation, this screen is selected when there are findings regarding the medical image displayed on the display 24. The main functions of the interpretation field selection screen will be briefly described.

First, the “abnormal part selection” button is used to select an abnormal part from a schema, and the part selected by the selection is automatically converted into characters and registered. Here, the “abnormal part selection” button is in the form of a toggle button, and as shown in FIG. 8A, nine buttons formed on each part of the chest are arranged, and one of them is selected (clicked). Then, the color of the button (part) is reversed, the part is specified, and the character is automatically converted and registered. Since the “abnormal part selection button” is a toggle button format, nine buttons can be selected as described above, or the selection can be canceled.
For example, when the 4th button <before selection> on the left side of FIG. 8 (a) is selected, the color of the 4th button on the right side <after selection> is inverted, and the "left middle lung field" ”And registered as a result.
For example, the following input items can be given as the registered characters of the region corresponding to the button number of the chest schema shown in FIG.
Part No. Input Item Part No. Input Item Part No. Input Item 1 Right lower lung field 4 Right middle lung field 7 Upper right lung field 2 Lower mediastinal part 5 Middle mediastinum part 8 Upper mediastinum part 3 Left lower lung field 6 Left lower lung field 6 Left middle lung field 9 Upper left lung field FIGS. 8B and 8C show the stomach and mammo schema, respectively. Also in the stomach and mammo, when one of the buttons is selected (clicked), the color of the button (part) is reversed, and the characters are automatically converted and registered.

Next, the “finding selection column” shown in FIG. 7 is a drop-down format for selecting finding items. The input items in the finding column are as follows and are stored in the finding column. Examples of input items in the observation column include the following.
The input items can be changed.
<Input items>
Atelectasis, mediastinal enlargement, pleural effusion, pleural thickening, pleurodesis, thoracic deformity, cardiac shadow enlargement, chest wall tumor and others, "diagnosis selection column" and "judgment selection column" are also "finding selection column" Exactly the same, it is a drop-down format, and the following input items can be listed as selectable diagnosis items and determination items.
<Input items in diagnosis column>
No abnormalities, intrathoracic lesions, respiratory tract lesions / chronic obstructive pulmonary disease and its surroundings, mediastinal lesions, pleural lesions,
Diaphragmatic lesions, rib lesions, thoracic and pleural lesions, cardiovascular lesions, congenital lesions, postoperative changes,
Other <Input items in the judgment field>
No abnormalities, minor abnormalities but no problems in daily life, minor abnormalities, requiring lifestyle improvement,
