MEDICAL IMAGE PROCESSING DEVICE, X-RAY DIAGNOSTIC APPARATUS, AND MEDICAL IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a medical image processing device capable of acquiring a blood vessel image by which a blood vessel into which a contrast medium flows can be identified more clearly.SOLUTION: A medical image processing device includes a blood vessel image generation part and a pixel value scale generation part. The blood vessel image generation part acquires a timewise change in the concentration of a contrast medium on the basis of at least X-ray contrast image data, and generates blood vessel image data having a pixel value corresponding to the time that the concentration of the contrast medium is a specific condition according to a gray scale or a color scale. The pixel value scale generation part generates the gray scale or the color scale by assigning the change in the pixel value to a period shorter than the period from the initial time to the finish time of the timewise change in the concentration of the contrast medium.
