Abstract: A console of a mobile radiography apparatus includes a CPU that acquires a fluoroscopic image captured by a radiation detector and a visible light image captured by a visible light camera as a moving image related to the capture of the fluoroscopic image of a subject by the mobile radiography apparatus. The CPU extracts a frame to be subjected to a support process, which is a diagnosis support process or an imaging support process, from the moving image. A GPU executes the support process for the extracted frame.

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: Fifteen radiation tubes are arranged in a radiation source of the mammography apparatus. An irradiation field limiter has a plurality of first irradiation opening portions which are provided in an X direction and each of which is configured by a pair of a first opening and a second opening facing each other in an irradiation direction of radiation and defines an irradiation field of the radiation. The irradiation field limiter includes a first rotating member that is rotated to a first rotation position and a second rotation position about a rotating shaft parallel to the X direction. At the first rotation position and the second rotation position, the first irradiation opening portions which are arranged at an interval of one radiation tube face the radiation tubes in the irradiation direction. The first irradiation opening portions deviate from each other in the X direction. Among 15 radiation tubes, at least some of second radiation tubes, which are other than first radiation tubes facing the first irradiation opening portions at the first rotation position and do not face the first irradiation opening portions, face the first irradiation opening portions at the second rotation position.

Abstract: An acquisition unit of a console acquires a first radiographic image and a second radiographic image. The first radiographic image and the second radiographic image are radiographic images which are output from a radiation detector by directing a radiation source to emit first radiation and second radiation in order to perform a moving image capture mode that continuously acquires a radiographic image required for the display of a moving image according to a preset frame interval. A receiving unit receives a request signal to request the generation of an energy subtraction image referred to for diagnosis. A generation unit generates the energy subtraction image in a case in which the receiving unit receives the request signal.
