Abstract: A medical information processing apparatus according to an aspect of the present invention is a medical information processing apparatus including a processor. The processor is configured to execute a spatial information acquisition process of sequentially acquiring pieces of spatial information of a lumen on the basis of endoscopic images sequentially acquired by an endoscope; an estimation process of estimating, on the basis of the pieces of spatial information sequentially acquired, at least one of a three-dimensional environment map of the lumen or a distal end position of the endoscope; a reference information acquisition process of acquiring reference information about a shape and/or an absolute size of the lumen; and a correction process of correcting, using the reference information, one or more of the spatial information, the three-dimensional environment map, and the distal end position of the endoscope.

Abstract: Provided are an image processing apparatus, method, and program that can appropriately support a treatment using an instrument. An image processing apparatus for processing an image captured with an endoscope having a distal end from which an instrument is protrudable includes a processor. The processor is configured to perform a process of acquiring an image captured with the endoscope, a process of causing a display to display the acquired image, a process of detecting a region of interest from the acquired image, a process of determining whether the region of interest is present at a position reachable by the instrument protruded from the distal end of the endoscope, and a process of providing a notification in a case where it is determined that the region of interest is present at a position reachable by the instrument protruded from the distal end of the endoscope.

Abstract: An object is to provide an endoscopic image learning device, an endoscopic image learning method, an endoscopic image learning program, and an endoscopic image recognition device that appropriately learn a learning model for image recognition for recognizing an endoscopic image in which a treatment tool for an endoscope appears.
The object is achieved by an endoscopic image learning device including an image generation unit and a machine learning unit. The image generation unit generates a superimposed image where a foreground image in which a treatment tool for an endoscope is extracted is superimposed on a background-endoscopic image serving as a background of the foreground image, and the machine learning unit performs the learning of a learning model for image recognition using the superimposed image.-

Abstract: A region of interest located in a first part to be observed is detected from a medical image at a first timing. In a case where a tip portion of an endoscope moves from the first part to be observed toward a second part to be observed and then moves to the first part to be observed again, a return determination unit performs first determination processing for determining whether the tip portion has returned to the first part to be observed, by using a medical image acquired a second timing. A display control unit performs display control of a monitor by using a determination result of the return determination unit.

Abstract: A processor device includes an image signal acquiring unit, an image processing unit, and a display control unit. The image signal acquiring unit acquires a digital image signal corresponding to an observation mode from an endoscope. The image processing unit includes a region-of-interest-detection-mode image processing unit. The region-of-interest-detection-mode image processing unit detects a region of interest from an endoscopic image and outputs a detection result of the region of interest and a cumulative detection time period of the region of interest.

Abstract: There is provided an endoscope system that appropriately gives a notification of the result of detection of a region of interest. The above-described issue is addressed by an endoscope system that is an endoscope system for performing an examination of a lumen of a patient, the endoscope system including: an insertion part that is inserted into the lumen; a camera that performs image capturing of the lumen to obtain an endoscopic image; a region-of-interest detection unit that detects a region of interest from the endoscopic image; a detection result notification unit that gives a notification of a result of detection of the region of interest; an insertion-withdrawal determination unit that determines whether a step to be performed in the examination is an insertion step or a withdrawal step; and a notification control unit that causes the detection result notification unit to give the notification in accordance with the step determined by the insertion-withdrawal determination unit.

Abstract: There is provided an endoscope device, an endoscope operation method, and a program which can allow the operator to simply perform operations using mechanisms and buttons of an operation unit already provided, without confusing the assigned operations. An endoscope device (10) includes a motion pattern identification unit (103) that identifies a single or plurality of motion patterns indicating a specific movement of a scope head of a scope unit; an operation storage unit (101) that stores a single or plurality of pieces of operation information for instructing an operation of the endoscope device, and the single or plurality of motion patterns of the scope head in association with each other; an operation information acquisition unit (105) that acquires the operation information corresponding to the motion pattern from the operation storage unit on the basis of the motion pattern identified by the motion pattern identification unit; and an operation execution unit (107) that executes an operation corresponding to the operation information acquired by the operation information acquisition unit.
