Abstract: According to an embodiment, a medical image processing device includes processing circuitry. The processing circuitry acquires a medical image obtained by imaging at least an artery. The processing circuitry detects a branch point of the artery on the basis of the medical image. The processing circuitry identifies a dominated region affected by the artery on a downstream side of the branch point in the medical image. The processing circuitry causes a display to display the dominated region.

Abstract: A medical image processing apparatus according includes processing circuitry. The processing circuitry is configured to calculate, from a plurality of medical X-ray fluoroscopic images, a size of a thrombus removal device that has been placed in a blood vessel of a subject and appears in the medical X-ray fluoroscopic image. The processing circuitry is configured to calculate change information indicating a change in the size from the plurality of medical X-ray fluoroscopic images. The processing circuitry is configured to calculate first time information indicating a time period during which the thrombus removal device is left in place in the subject, based on the change information. The processing circuitry is configured to perform control to output the first time information.

Abstract: A medical image-processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a first medical image captured at first timing, and a second medical image in which an identical position to the first medical image is captured at second timing, which is different from the first timing, identifies a change region to be a logical OR of a first region included in the first medical image and a second region that corresponds to the first region and is included in the second medical image when the first medical image and the second medical image are overlaid on each other in an aligned manner, and calculates a degree of change of the change region between the first timing and the second timing based on the first region and the second region that form the change region.
