Abstract: A diagnostic assistance apparatus includes a processor. The processor is configured to acquire a first ultrasound image generated by an ultrasound module, and switch between a first operating mode and a second operating mode according to whether or not reference information is combined with the first ultrasound image, according to whether or not the first ultrasound image is an image obtained in an auxiliary image mode, or according to a set value that stipulates the image quality of the first ultrasound image. The first operating mode is an operating mode that performs detection of a specific area on the basis of detection assistance information created using a second ultrasound image obtained in a main image mode. The second operating mode is an operating mode that performs detection of the specific area but does not output a detection result, or that does not perform detection of the specific area.

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 medical image processing apparatus includes a processor configured to execute an image acquisition process for sequentially acquiring time-series medical images; a region-of-interest recognition process for recognizing a position and a type of a region of interest from the medical images; and a display control process for causing a display device to display position information indicating the position of the region of interest and type information indicating the type of the region of interest such that the position information and the type information are superimposed on the medical images. In the display control process, the processor changes a position at which the position information is to be displayed according to a change in the position of the region of interest over time, and maintains a position at which the type information is to be displayed regardless of a change in the position of the region of interest over time.

Abstract: Provided are a medical image processing apparatus, a medical image processing method, a program, and a diagnosis support apparatus that report a region of interest without hindering observation of the boundary between the region of interest and a region of non-interest in a medical image. A medical image processing apparatus includes a superimposition processing unit that superimposes, on a medical image, a figure for reporting a region of interest included in the medical image. The superimposition processing unit superimposes the figure on an inside of the region of interest such that at least part of a boundary between the region of interest and a region of non-interest is not superimposed with the figure, thereby reporting the region of interest without hindering observation of the boundary between the region of interest and the region of non-interest.
