Abstract: A CPU acquires a distance image which indicates a distance to an imaging target and is captured by a TOF camera using, as an imaging region, a region including at least a portion of a region in which an attachable and detachable member is attached to a mammography apparatus. Further, the CPU acquires reference distance information related to a reference value of a distance between the attachable and detachable member and the TOF camera in a state in which the attachable and detachable member is attached to the mammography apparatus. Furthermore, the CPU determines whether or not the attachable and detachable member is attached to the mammography apparatus on the basis of the distance image and the reference distance information.

Abstract: A console includes an image processing unit, a defective pixel map data acquisition unit, a failure condition estimation unit, a notification unit, and a display unit. The defective pixel map data acquisition unit acquires defective pixel map data output from a radiography unit. The failure condition estimation unit receives the defective pixel map data acquired by the defective pixel map data acquisition unit and estimates the failure probability of the radiography unit or the usage state of the radiography unit at the time of failure.
