Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured: to perform registration between one contrast image and each of a plurality of mask images; to calculate a plurality of matching degrees between the plurality of mask images and the one contrast image registered with each other, on the basis of the plurality of mask images and the one contrast image registered with each other; and to determine a difference between one of the mask images corresponding to a maximum matching degree among the plurality of matching degrees and the one contrast image, as one subtraction image corresponding to the one contrast image.
