Abstract: A medical image-processing apparatus according to an embodiment includes processing circuitry configured to determine a position of a feature point of a device in a first X-ray image, and generate a superimposed image in which a 3D model expressing the device is superimposed on the first X-ray image or a second X-ray image that is acquired later than the first X-ray image. The processing circuitry is configured to superimpose the 3D model on the first X-ray image or the second X-ray image at a position based on the position of the feature point.

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.
