Abstract: 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.

Abstract: A medical image processing apparatus includes processing circuitry. The processing circuitry obtains activity position data related to positions of activity regions that bring a site of an examined subject into an activity and a blood vessel image rendering a three-dimensional blood vessel related to the activity regions. The processing circuitry performs a registration between the activity position data and the blood vessel image. The processing circuitry calculates a positional relationship between at least one of the activity regions and the blood vessel, on the basis of a result of the registration. On the basis of the positional relationship, the processing circuitry causes a display to display information about positioning a device capable of receiving, within the blood vessel of the examined subject, electrical signals from the activity regions.

Abstract: An X-ray diagnostic apparatus according to an embodiment includes a processor. The processor sequentially acquires ultrasonic image data generated from a signal collected from a detector of an ultrasonic catheter that is inserted into a body of a subject. The processor collects a plurality of pieces of X-ray image data acquired from a plurality of directions and detects the ultrasonic catheter and a treatment device on the X-ray image data. The processor calculates coordinates indicating a current position of the treatment device on the X-ray image data based on information about a user operation for the ultrasonic catheter received from a robot catheter system, the treatment device detected on the ultrasonic image data, and a result of detection by the detector. The processor displays a display image that is obtained by superimposing positional information including the coordinates indicating the current position of the treatment device onto the X-ray image data.

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.
