According to one embodiment, a medical image processing apparatus includes a subtraction image acquisition part, a threshold processing part, an image processing part and an image operation part. The subtraction image acquisition part is configured to acquire subtraction image data between X-ray contrast image data and X-ray non-contrast image data of an object. The threshold processing part is configured to perform threshold processing of the subtraction image data or image data generated based on the subtraction image data. The image processing part is configured to perform image processing of image data after the threshold processing. The image operation part is configured to generate image data for a display by an image operation between the subtraction image data and image data after the image processing.
