Abstract
According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry obtains first and second blood vessel image by image generation processing which obtains time phase changes in concentrations of a contrast agent based on X-ray contrast image and generates time phase image according to a gray or color scale. The time phase image has pixel values corresponding to time phases at which the concentrations of the contrast agent become a specific condition. The image generation processing is performed multiple times based on X-ray contrast images acquired at different times. Further, the processing circuitry determines or corrects pixel values or time phases of at least one of the first and second blood vessel image, to make a pixel value of a time phase of the first blood vessel image coincident with that of the second blood vessel image.
