Abstract: A control device including: a control unit that, in a case in which continuous imaging that irradiates a breast of a subject with radiation emitted from a radiation source to capture a radiographic image in a compressed state in which the breast is compressed against an imaging table by a compression member and then captures an ultrasound image of the breast in the compressed state is performed, performs control to locate the radiation source at a non-facing position where the radiation source and the imaging table do not face each other.

Abstract: A mammography apparatus includes a compression control unit that, in a case in which continuous imaging that captures a radiographic image of the breast compressed by a compression plate and then captures an ultrasound image of the breast while maintaining the compressed state is performed, performs control to set a force of the compression plate compressing the breast to a first force in the capture of the radiographic image and to change the force of the compression plate compressing the breast from the first force to a second force lower than the first force in the capture of the ultrasound image.

Abstract: A compression plate of a mammography apparatus has an upper surface which is irradiated with radiation, a lower surface which is opposite to the upper surface and comes into contact with the breast, and a surface which is parallel to the upper surface between the upper surface and the lower surface. In the compression plate, a compression plate scale for identifying an in-plane position of each surface is given to any one of the surfaces. A first display control unit of a console performs control to display a radiographic image captured by the mammography apparatus on a display unit. A second display control unit of the console performs control to display an image scale which indicates a position on the radiographic image corresponding to the in-plane position of the compression plate on the radiographic image displayed on the display unit.

Abstract: A reconstruction unit generates a plurality of tomographic images representing a plurality of tomographic planes of a subject by reconstructing a plurality of projection images acquired by performing tomosynthesis imaging. A synthesis unit synthesizes the plurality of tomographic images to generate a composite two-dimensional image. A display control unit displays the composite two-dimensional image on a display, and in a case where one tissue of a first tissue and a second tissue that are present in the subject in association with each other is selected in the displayed composite two-dimensional image, emphasizes and displays the selected one tissue and the other tissue associated with the selected one tissue.

Abstract: An acoustic matching member configured to be disposed between a breast placed on an imaging table and a compression plate disposed opposite to the imaging table is proposed. The acoustic matching member includes a protruding portion that protrudes toward the imaging table and that is provided in an end portion on a deepest side when viewed from a chest wall side of a subject in a case of compressing a breast of the subject in contact with the compression plate.

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.
