Abstract: A control method of an information terminal causes a display to display a display screen which includes a first display region and a second display region. The first display region displays an object medical image. The second display region displays M number of similar medical images and includes ND number of individual regions for displaying the M number of the similar medical images. When an instruction from one or more instruction buttons is detected, a display size of each corresponding region of interest that is included in the second number of the similar medical images is changed while maintaining a size of each of the individual regions in the second display region, and each of the similar medical images is magnified at a magnification ratio of a reference thumbnail.

Abstract: If a lesion included in a specification target image is a texture lesion, a probability image calculation unit calculates a probability value indicating a probability that each of a plurality of pixels of the specification target image is included in a lesion area. An output unit calculates, as a candidate area, an area including pixels whose probability values are equal to or larger than a first threshold in a probability image obtained from the probability image calculation unit and, as a modification area, an area including pixels whose probability values are within a certain probability range including the first threshold. An input unit detects an input from a user on a pixel in the modification area. A lesion area specification unit specifies a lesion area on the basis of the probability image, the candidate area, the modification area, and user operation information.

Abstract: A display control unit vertically divides a case display area in accordance with the number of disease names selected by a user to create a number of sub-areas equal to the number of disease names. Each of the sub-areas is vertically elongated so that thumbnail images of similar cases of the corresponding disease name are displayed so as to be aligned in a column. The display control unit displays, in each sub-area, thumbnail images of similar cases of the corresponding disease name so that the thumbnail images are aligned in a column in order of decreasing similarity to a search query image displayed in a layout area.

Abstract: A medical image managed by a medical information management system is displayed in a layout region that is displayed on a display of an information terminal, and thumbnail images of similar cases received from a case retrieval system are displayed in a case display region. In the layout region, a display box displaying a thumbnail image of a diagnosis object case and display boxes displaying thumbnail images selected from the thumbnail images displayed in the case display region are displayed adjacent to one another.

Abstract: A display control unit vertically divides a case display area in accordance with the number of disease names selected by a user to create a number of sub-areas equal to the number of disease names. Each of the sub-areas is vertically elongated so that thumbnail images of similar cases of the corresponding disease name are displayed so as to be aligned in a column. The display control unit displays, in each sub-area, thumbnail images of similar cases of the corresponding disease name so that the thumbnail images are aligned in a column in order of decreasing similarity to a search query image displayed in a layout area.

Abstract: A control method of an information terminal according to the present disclosure causes a display to display a display screen which includes a first display region displaying an object medical image and a second display region displaying M number of similar medical images. When one instruction for magnifying any one similar medical image among the M number of similar medical images is sensed, with respect to the M number of or fewer similar medical images in the M number of ranges that are displayed in the second display region upon sensing the one instruction, a corresponding region of interest in each of the M number of or fewer similar medical images is magnified so as to match a position corresponding to a center of each of individual regions in the second display region while maintaining a size of each of the individual regions at a same size.

Abstract: Similar medical images having a predetermined similarity to a region of interest in a medical image to be interpreted are received from a case search system. A display screen on which the received similar medical images are displayed is displayed on a display. The display screen includes display frames within which similar medical images are displayed. In response to an instruction for enlarging the similar medical images, corresponding regions of interest in the similar medical images are enlarged and displayed with the sizes of the display frames maintained unchanged on the display screen. In response to an instruction for causing a selected similar medical image among the enlarged and displayed similar medical images to move within a corresponding display frame, the other unselected similar medical image(s) is caused to move within a corresponding display frame synchronously with the movement of the selected similar medical image in the same movement direction.
