Abstract
An image processing apparatus includes at least one processor that is configured to: acquire a low-energy image captured by a radiography apparatus by emitting radiation having first energy to a subject into which a contrast medium has been injected, and a plurality of high-energy images captured by the radiography apparatus by emitting radiation having second energy higher than the first energy at a plurality of different imaging timings after the injection of the contrast medium, and generate a second difference image showing a difference between a plurality of first difference images showing a difference of the low-energy image and each of the plurality of high-energy images to remove a pixel value corresponding to the contrast medium that has permeated outside a region of interest.
