Abstract: A processor acquires a non-contrast CT image of a head of a patient and first information representing any one of an infarction region or a large vessel occlusion region in the non-contrast CT image, and derives second information representing the other of the infarction region or the large vessel occlusion region in the non-contrast CT image based on the non-contrast CT image and the first information.

Abstract: A support program is a program for supporting creation of an interpretation report including a medical image obtained by examining a patient and a region of interest to focus on in the medical image. The support program causes a computer to function as: a reading unit that reads a plurality of interpretation reports created by a plurality of examinations on the same part of the same patient; a difference detection unit that sets one of the plurality of interpretation reports as a detection target interpretation report and sets the others as comparison target interpretation reports, compares regions of interest of the detection target interpretation report and the comparison target interpretation reports, and detects a region of interest, which is present in the comparison target interpretation reports but is not present in the detection target interpretation report, as a difference region; and a notification screen distribution unit that, in a case where the difference region is detected, notifies that the difference region has been detected.

Abstract: A processor acquires a medical image and a first disease region in the medical image, derives a second disease region related to the first disease region in the medical image based on the medical image and the first disease region, updates the first disease region based on the medical image and the second disease region, updates the second disease region based on the medical image and the updated first disease region, and repeats update of the first disease region and update of the second disease region until a predetermined end condition is satisfied.

Abstract: An image acquisition unit acquires a CT image and one or more MRI images of the brain of a subject that has developed a cerebral infarction. An infarction region extraction unit extracts an infarction region corresponding to the time elapsed since the development from the MRI image. A registration unit performs registration between the CT image and the MRI image. An infarction region specification unit specifies the infarction region corresponding to the time elapsed since the development in the CT image on the basis of the result of the registration. A learning unit learns a discriminator which discriminates an infarction region corresponding to the time elapsed since the development in the CT image to be discriminated, using the infarction region corresponding to the time elapsed since the development, which has been specified in the CT image, as teacher data.

Abstract: An analysis unit analyzes a medical image and acquires an analysis result. An interpretation report creation unit creates an interpretation report on a disease based on the analysis result. A display control unit displays the medical image and the interpretation report on a display. In response to an instruction to modify one of a disease region in the medical image and a description of the disease region in the interpretation report, a modification unit modifies the other one of the disease region in the medical image and the description of the disease region in the interpretation report.

Abstract: A processor acquires at least one of first information representing any one of an infarction region or a large vessel occlusion region in a non-contrast CT image of a head of a patient, information representing an anatomical region of a brain, or clinical information, acquires second information representing a candidate of the other of the infarction region or the large vessel occlusion region in the non-contrast CT image, and derives third information representing the other of the infarction region or the large vessel occlusion region in the non-contrast CT image based on at least one of the first information, the information representing the anatomical region of the brain, or the clinical information, and the second information.

Abstract: An image processing apparatus includes at least one processor, and the processor derives three-dimensional coordinate information that defines a position of a structure in a tomographic plane from a tomographic image including the structure, and that defines a position of an end part of the structure outside the tomographic plane in a direction intersecting the tomographic image.
