Image processing apparatus, image capturing system, image processing method, and image processing program

Abstract

An image processing apparatus includes at least one processor, and the processor is configured to: acquire a synthesized two-dimensional image including information in a depth direction of a breast, the synthesized two-dimensional image being a composite image obtained by synthesizing a plurality of radiation images of the breast imaged in a compression state by a compression member; display the synthesized two-dimensional image; acquire position information indicating a position in the displayed synthesized two-dimensional image; acquire a plurality of ultrasound images of the breast imaged in a compression state by the compression member, the compression state which is considered to be the same as that in capturing the radiation image; and display an ultrasound image for display according to the plurality of ultrasound images with depth information indicating a depth of the breast corresponding to the position indicated by the position information added thereto.
