摘要： A processor of an ophthalmologic image processing device acquires an ophthalmologic image photographed by an ophthalmologic image photographing device. The processor inputs the ophthalmologic image into a mathematical model trained by a machine learning algorithm to acquire a result of an analysis relating to at least one of a specific disease and a specific structure of a subject eye. The processor acquires information of a distribution of weight relating to an analysis by a mathematical model, as supplemental distribution information, for which an image area of the ophthalmologic image input into the mathematical model is set as a variable. The processor sets a part of the image area of the ophthalmologic image, as an attention area, based on the supplemental distribution information. The processor acquires an image of a tissue including the attention area among a tissue of the subject eye and displays the image on a display unit.

摘要： A target image to be corrected is generated by arranging partial images acquired by scanning a tissue of a living body with light and temporally continuously receiving the light from the tissue. A processor of a medical image processing device performs detecting position shift amounts, acquiring a component, and correcting. In the process of detecting position shift amounts, the processor detects the position shift amounts between the partial images (S3). In the process of acquiring, the processor acquires an assumed result of at least one of a component in the position shift amount caused by movement of the tissue, and a component in the position shift amount caused by a shape of the tissue (S4). In the process of correcting, the processor corrects a position of each of the partial images based on the component in the position shift amount (S7).

摘要： An ophthalmologic information processing device includes a processor and a memory that stores computer-readable instructions. The computer-readable instructions, when executed by the processor, cause the ophthalmologic information processing device to perform processes that include setting a target position on an ocular fundus of a patient's eye, determining a position of one of a ganglion cell corresponding to a photoreceptor cell present at the target position and a photoreceptor cell corresponding to a ganglion cell present at the target position, and obtaining a first analysis result of a retina at the determined position based on one of a second analysis result and a third analysis result. The second analysis result includes an analysis result of the retina at a center point of the determined position and an analysis result of the retina at an auxiliary point. The third analysis result includes an analysis result of the retina in an analysis region.
