Mode for Carrying Out the Invention

[0018] [First Embodiment] As shown in FIG. 1, the medical image processing apparatus 10 is connected to the endoscope system 11. The endoscope system 11 acquires a large number of medical images 12 by the light source device 11a, the endoscope 11b, and the processor device 11c. The light source device 11a supplies illumination light for illuminating the inside of the body to the endoscope 11b. The endoscope 11b irradiates the illumination light toward the inside of the body, receives and images the reflected light from the inside of the body, thereby acquiring an endoscope image of the inside of the body. The processor device 11c performs image processing on the endoscope image from the endoscope 11b and displays it on an endoscope display (not shown). The endoscope system 11 is connected to the medical image processing apparatus 10 and transmits the acquired endoscope image to the medical image processing apparatus 10 as the medical image 12.

[0019] In the medical image processing apparatus 10, programs related to various processes are incorporated in a program memory (not shown). The medical image processing apparatus 10 is provided with a central control unit (not shown) constituted by a processor. By executing the program in the program memory by the central control unit, as shown in FIG. 2, the functions of an image acquisition unit 20, an image classification unit 21, a display control unit 22, an input reception unit 23, an image group determination unit 24, a usefulness determination unit 25, an image selection unit 26, and a report creation device 27 are realized. Further, the medical image processing apparatus 10 is provided with a display 30 for displaying various images.

[0020] The medical image processing apparatus 10 performs a process of selecting a report attached image, which is a medical image to be attached to a report created by the report creation device 27, from among the medical images obtained by the endoscope system 11.

[0021] The image acquisition unit 20 acquires a plurality of medical images 12 from the endoscope system 11 and transmits them to the image classification unit 21. The image classification unit 21 extracts the image information of the medical images 12 transmitted from the image acquisition unit 20, and acquires category information and calculates image quality information. According to the acquired category information, the medical images 12 are classified into respective categories.

[0022] The categories to be classified are any one or a combination of the imaging site, the presence or absence and type of a lesion which is one of the regions of interest, the usage state of a treatment tool, the spraying state of a contrast agent, etc. In the image quality information, information such as the brightness, noise, and blur degree of the image is acquired and attached to the medical images 12. For the extraction of the image information, a learned CNN (Convolutional Neural Network) model is used. The learned CNN is obtained by learning using an image group including at least a plurality of medical images 12. The category information and the image quality information acquired during imaging by the endoscope system 11 and attached to the medical images 12 are model preferred to be prioritized over the information extracted by the learned CNN. preferred.

[0023] As shown in FIG. 3, the display control unit 22 displays a list of a plurality of medical images 12 on the first display screen 30a of the display 30. By displaying a list of such a plurality of medical images 12, selection by the user becomes possible. Note that the medical images 12 to be displayed in a list on the first display screen 30a are preferably medical images 12 that have been category-classified into a plurality of categories by the image classification unit 21, or medical images 12 that are unclassified and not classified into a plurality of categories by the image classification unit 21.

[0024] The input reception unit 23 receives at least a user's designated input with respect to the medical image 12 displayed on the display 30. Specifically, as shown in FIG. 3, a cursor 32 that reflects a user operation by a mouse operation or the like is displayed on the display 30, and the user uses the cursor 32 to perform a designated input with respect to the medical image 12. The designated input can be performed not only on a single medical image but also on a plurality of medical images. The input reception unit 23 receives the designated input designated by the cursor 32. When the designated input with respect to the medical image is completed, the designated input completion icon 33 is operated using the cursor 32. Note that the designated medical image 12 is preferably displayed with a thick frame 13 added to the outer edge, or with a mark indicating the designated input added. ri When the designated input with respect to the medical image is completed, the designated input completion icon 33 is operated using the cursor 32. Note that the designated medical image 12 is preferably displayed with a thick frame 13 added to the outer edge, or with a mark indicating the designated input added.

[0025] The image group determination unit 24 determines a designated image group including the designated images that are the designated input medical images, and a non-designated image group including non-designated images that are medical images not designated among the plurality of medical images acquired by the image acquisition unit 20. Specifically, as shown in FIG. 4, at the time of completion of the designated input when the input reception unit 23 receives an instruction of completion of the designated input, the medical images 12 that have been designated are set as designated images 35, and a designated image group 36 including those designated images 35 is determined. Also, the medical images 12 that have not been designated at the time of completion of the designated input are set as non-designated images 38, and a non-designated image group 39 including those non-designated images is determined.

[0026] In the usefulness determination unit 25, the diagnostic usefulness of the medical image 12 is determined based on the classification result obtained by the image classification unit 21 and the image quality information. The higher the diagnostic usefulness, the higher the possibility that the image is suitable as an attached image for the report. The evaluation of the usefulness is represented by, for example, a step evaluation. In the classification result of the category, items such as lesions are included, and a medical image 12 with a low degree of blurring in the image quality evaluation can be evaluated as having high usefulness. When there is no category information, the degree of blurring is large, the brightness is too high, or the brightness is too low, the usefulness is low. The medical image 12 for which the usefulness determination has been completed is transmitted to the image selection unit 26. The usefulness is evaluated, and the evaluation threshold can be arbitrarily set by the user. Note that the usefulness determination may be performed on the designated image 35 or the non-designated image in addition to the medical image 12.

[0027] The image selection unit 26 acquires a selected image selected from among a plurality of medical images 12 based on the designated image category, which is the category attached to the designated image 35, and the non-designated image category, which is the category attached to the non-designated image 38. More preferably, the image selection unit 26 may acquire the selected image based on the usefulness obtained by the usefulness determination unit 25 in addition to the designated image category and the non-designated image category. Note that it is preferable to determine the number of selected images such that the sum of the number of designated images and the number of selected images is a specific number. Also, the number of selected images may be set to the number specified by the doctor. The number setting is preferably received by the input reception unit 23.

[0028] Specifically, as shown in FIG. 5, the selected image 40 obtained by the image selection unit 26 preferably includes a first selected image 42 selected from the non-designated image group 39 based on the relationship between the designated image category and the non-designated image category. The relationship between the designated image category and the non-designated image category is preferably a relationship in which the designated image category and the non-designated image category are different. In this case, examples of the first selected image 42 include "a non-designated image 38 of a photographing site different from the designated image 35", "when the designated image 35 includes a lesion, a non-designated image 38 that does not include a lesion", "when the designated image 35 is during the use of a treatment tool, a non-designated image 38 in which the treatment tool is not used", and "when the designated image 35 is during dye spraying, a non-designated image 38 in which dye spraying is not performed". On the other hand, the selected image 40 preferably includes a second selected image 44 in which all of the designated images 35 included in the designated image group 36 are selected.

[0029] As shown in FIG. 6, the display control unit 22 displays the selected image 40 on the second display screen 30b of the display 30. When the user confirms the selected image 40 and determines that it is suitable as a report attachment image to be used in the report creation device 27, the user operates the approval icon 46 displayed on the display 30 using the cursor 32. When the approval icon 46 is operated, the selected image 40 is transmitted to the report creation device 27 as a report attachment image. On the other hand, when the selected image 40 is not approved as a report attachment image, the disapproval icon 47 is operated. In this case, the display 30 switches to the first display screen 30a and switches to a state of accepting the user's designated input.

[0030] As described above, before automatically selecting the report attachment image, the user selects the second selected image 44, and then automatically selects the first selected image 42, and sets the selected image 40 including the first selected image 42 and the second selected image 44 as the report attachment image to be used in the report creation device 27, thereby reflecting the preferences of the doctor who is the user and reducing the burden of the report creation work.

[0031] In the second display screen 30b, it is preferable that the display modes of the images corresponding to the designated image 35 and the non-designated images 38 among the selected images 40 are different. For example, as shown in FIG. 7, for the image 50 corresponding to the designated image 35, a thick frame 51 is displayed on the outer edge, while for the image 52 corresponding to the non-designated image 38, the thick frame 51 is not displayed.

[0032] Also, in the first display screen 30a, it is preferable that the display modes of the respective medical images 12 differ depending on the category, and in the second display screen 30b, it is preferable that the display modes of the respective selected images 40 differ depending on the category. For example, as shown in FIG. 8, in the second display screen 30b, characters 54 corresponding to the category are assigned to each of the selected images 40. Examples of the characters corresponding to the category include the site name, lesion name, light source used, and presence or absence of treatment with a treatment tool. Further, symbol information corresponding to the category may be assigned to and displayed on each of the selected images 40. Examples of the symbol information corresponding to the category include information obtained by symbolizing the site name, lesion name, light source used, and presence or absence of treatment with a treatment tool. For example, in the case of using an upper endoscope, the esophagus, stomach, and duodenum may be designated as "area1", "area2", and "area3" in the order of insertion. In addition, in the first display screen 30a as well, it is preferable to assign and display characters or symbol information corresponding to the category to each of the medical images 12 by the same method as in the second display screen 30b described above.

[0033] Regarding the display mode of the medical image 12 or the selected image 40 according to the category, as described above, it may be a mode without using characters or symbols. For example, on the first display screen 30a or the second display screen 30b, the display position of the medical image 12 or the selected image 40 may be changed according to the category. For example, when the medical image or the selected image 40 is displayed along the row direction (vertical direction), it is preferable to display the medical images 12 or the selected images 40 of different categories in one or more row units. Thereby, on the first display screen 30a, it becomes easier for the user to select (designate and input) the medical image 12, and on the second display screen 30b, it becomes easier to grasp the categories of the image group to be included in the report.

[0034] In addition, on the first display screen 30a, as shown in FIG. 9, it is preferable to list and display specific medical images 55 that satisfy specific conditions regarding the category and / or diagnostic usefulness among the plurality of medical images 12. The input reception unit 23 receives the user's designated input for the specific medical image 55 listed and displayed on the first display screen 30a. As described above, by listing and displaying only the specific medical images 55 instead of all the medical images, the burden on the user due to the designated input can be reduced. As the specific conditions, it is preferable to include at least one of the following: the number of images included in the same category is less than or equal to a specific number, or the image has high diagnostic usefulness. Note that the medical images 56 other than the specific medical images 55 are not subject to the designated input. In this case, as the display mode of the medical images 56 other than the specific medical images 55, although the visibility is lower than that of the specific medical images 55, it is preferable to either leave the display on the first display screen 50a (for example, gray out), or completely exclude it from the first display screen 50a (non-display).

[0035] In the report creation device 27, as shown in FIG. 10, a report is created using the report creation screen 48 displayed on the display 30. The report creation screen 48 has a selection image 40 automatically attached thereto, and pre-input patient information, user information, etc. are automatically input. The user inputs findings, etc. in the findings input field 49 to create a report.

[0036] Next, a series of processes for selecting a report-attached image will be described along the flowchart of FIG. 11. The image acquisition unit 20 acquires a plurality of medical images 12 from the endoscope system 11. The image classification unit 21 classifies each medical image 12 into a plurality of categories. The display control unit 22 displays a list of the plurality of medical images on the first display screen 30a of the display 30. The input reception unit 23 receives a user's designated input for the medical images displayed on the first display screen 30a. When the user's designated input is completed, the designated input completion icon 33 is operated.

[0037] When the designated input completion icon 33 is operated, the image group determination unit 24 determines a designated image group 36 including the designated image 35 which is the designated medical image 12 input by designation, and a non-designated image group 39 including non-designated images 38 which are medical images 12 not input by designation among the plurality of medical images 12. The image selection unit 26 acquires a selected image 40 selected from among the plurality of medical images 12 based on the designated image category which is the category assigned to the designated image 35 and the non-designated image category which is the category assigned to the non-designated image 38. The display control unit 22 displays a list of the selected images 40 on the second display screen 30b of the display 30.

[0038] When the user approves the selected image 40 displayed in a list as a report-attached image, the approval icon 46 is operated. When the approval icon 46 is operated, the selected image 40 is transmitted to the report creation device 27 as a report-attached image. On the other hand, when the selected image 40 is not approved as a report-attached image, the disapproval icon 47 is operated. In this case, the display 30 switches to the first display screen 30a and switches to a state of receiving the user's designated input.

[0039] [Second Embodiment] In the second embodiment, every time a user's designated input is made, the medical images listed and displayed on the first display screen 30a are updated. Specifically, each time a designated input is made, the display control unit 22 updates the medical images listed and displayed on the first display screen 30a based on the designated image category and the non-designated image category. The input reception unit 23 receives the user's designated input for the updated medical images listed and displayed on the first display screen 30a.

[0040] For example, as shown in FIG. 12, when a designated input is made for a designated image X1 to which a specific designated image category X is assigned, the display control unit 22 performs an update to delete (make non-displayed on the first display screen 30a) a non-designated image X2 to which the same non-designated image category X as the specific designated image category X is assigned from the first display screen 30a. Thereby, since the number of images that the user should check is reduced, the work burden on the user can be reduced. Here, as the images to be deleted from the first display screen 30a along with the user's designated input, for example, "non-designated image X2 having the same imaging site as designated image X1", "non-designated image X2 having an imaging site close to designated image X1", "when designated image X1 is an image during treatment with a treatment tool or during dye spraying, non-designated image X2 during treatment or during dye spraying" is not is preferably "non-designated image X2". Regarding the non-designated image X2, in addition to making it non-displayed on the first display screen 30a, although its visibility is lower than that of the designated image X1, it may be left displayed on the first display screen 30a (for example, grayed out).

[0041] [Third Embodiment] In the third embodiment, when a specified input is performed, in order to make it easier to grasp the user's working situation, the display control unit 22 displays specified image information regarding the specified image on the display 30. As the specified image information, for example, it is preferably information that represents the position information of the part corresponding to the specified image in characters or visually. When the part corresponding to the specified image is the rectum, which is a predetermined position of the large intestine, as shown in FIG. 13, "rectum" is displayed on the display 30 as the character position information 62, or a point 58 indicating that a specified input has been performed is displayed on the display 30 at the part corresponding to "rectum" in the schema diagram 57 of the large intestine.

[0042] Further, as the specified image information, for example, it is preferably information that represents the number of specified images 35 in characters or visually. When the number of specified images 35 at the time when the specified input is performed is 4 four, as shown in FIG. 14, "four" is displayed on the display 30 as the character information 59, or the length 60a corresponding to "four" is displayed on the display 30 in the number count bar 60 representing the number of specified images 35.

[0043] In the above embodiment, the hardware structure of the processing unit that executes various processes such as the image acquisition unit 20, the image classification unit 21, the display control unit 22, the input reception unit 23, the image group determination unit 24, the usefulness determination unit 25, the image selection unit 26, and the report creation device 27 is various processors as shown below.
