According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry acquires correspondence information, based on 3D medical image data of an object, that corresponds a blood vessel to information on a dominant area of the blood vessel in a region of the object. The processing circuitry acquires a plurality of X-ray images each including the blood vessel that are collected at different time phases on the object. The processing circuitry identifies, based on the plurality of X-ray images, a flow changed vessel in which blood flow has changed between the different time phases. The processing circuitry performs registration between the flow changed vessel and the 3D medical image data. The processing circuitry estimates information on the dominant area corresponding to the flow changed vessel based on registration results and the acquired correspondence information.

Medical image processing apparatus, X-ray diagnostic apparatus, and storage medium

According to one embodiment, an X-ray diagnosis apparatus includes an X-ray tube, an X-ray detector, an operating unit, and processing circuitry. The processing circuitry determines a focal-spot size of X-rays in second moving picture imaging after first moving picture imaging, based on an output of the X-ray detector in the first moving picture imaging, and determines a focal-spot size of X-rays in third moving picture imaging after the second moving picture imaging, based on an output of the X-ray detector in the second moving picture imaging.
