Abstract: 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.

Abstract: In one embodiment, a medical image processing apparatus includes: processing circuitry configured to extract 3D blood vessel data of an object from 3D image data of the object, detect a tip position of a medical device moving in a blood vessel in real time from a fluoroscopic image of the object inputted during an operation, and calculate at least one of a recommended route and a recommended direction of the medical device from the 3D blood vessel data, a rough route of the medical device, and the tip position of the medical device; and a terminal device configured to display a 3D blood vessel image of the object generated from the 3D blood vessel data and to designate the rough route of the medical device on the 3D blood vessel image.

Abstract: In one embodiment, an X-ray diagnostic apparatus includes an X-ray source, an X-ray detector, an arm, and processing circuitry. The arm supports the X-ray source and the X-ray detector. The processing circuitry identifies a three-dimensional running direction of a blood vessel of an object from a plurality of images that are obtained by using the X-ray source and the X-ray detector to image the object from at least two different angles, and controls positions of the X-ray source and the X-ray detector by using the arm in such a manner that a target position of the blood vessel is imaged from the at least two different directions determined depending on the three-dimensional running direction.
