Abstract

Cross-correlation between a first magnetic resonance image as a reference image and a second magnetic resonance image to be adjusted relative to the first magnetic resonance image is taken, deviation of the second magnetic resonance image to the first magnetic resonance image as correction values is calculated, and the second magnetic resonance image based on the correction values is corrected.
