Radiation image processing apparatus and operation method thereof

Abstract

A processor provided in a radiation image processing apparatus acquires two radiation images obtained by imaging breasts of the same subject, calculates, based on the radiation images, a pixel mammary gland ratio, which is a ratio of a mammary gland for each pixel in each of the radiation images, calculates, based on the pixel mammary gland ratio, a region mammary gland ratio in a predetermined region of each of the radiation images, evaluates extensibility of the mammary gland by comparing two region mammary gland ratios respectively calculated using the two radiation images, and performs control to display an evaluation result of the extensibility.
