11. An image processing method comprising:
determining a plurality of locations of a pressure sensor that is inserted into a subject from each of a plurality of X-ray fluoroscopic images acquired sequentially;
determining a plurality of reference positions on a contrast X-ray image of the subject that correspond to the plurality of locations of the pressure sensor; and
causing a display to display the contrast X-ray image indicating one of a plurality of values derived from output of the pressure sensor, and to display a chart based on the plurality of values,
wherein the plurality of values are values related to blood flow.
