MEDICAL IMAGE PROCESSING APPARATUS, X-RAY DIAGNOSTIC APPARATUS, MEDICAL IMAGE PROCESSING METHOD AND X-RAY DIAGNOSTIC METHOD

摘要

According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry is configured to obtain time changes of concentrations of a contrast agent, based on at least X-ray contrast image data; generate a gray scale or a color scale by assigning a change in pixel value for at least one period, to a period shorter than a period from an initial time to an ending time of the time changes of the concentrations of the contrast agent; and generate blood vessel image data according to the gray scale or the color scale. The blood vessel image data have pixel values corresponding to times at which the concentrations of the contrast agent become a specific condition.
