18 Claims

1. A medical image processing apparatus, comprising: processing circuitry configured to acquire an X-ray image of a subject, acquire ultrasonic image data of the subject, extract a medical device contained in the acquired X-ray image, and perform processing based on a position of the extracted medical device in the ultrasonic image data in accordance with a relative positional relation between a coordinate system in the X-ray image and a coordinate system in the ultrasonic image data to generate a composite image as a combination of processed ultrasonic image data after being subjected to the processing and the X-ray image, wherein the processing circuitry is further configured to, as the processing, change a display parameter of a region containing the position of the extracted medical device in the ultrasonic image data so as to increase a transparency of the region.
