Abstract: A control device includes a control unit and a determination unit. The control unit controls an operation of radiation tubes such that radiation is emitted at irradiation positions whose number is smaller than the total number of irradiatable positions preset so as to correspond to irradiation angles. The determination unit determines whether or not the radiation needs to be additionally emitted at the irradiatable positions different from the irradiation positions in order to obtain the tomographic image with an image quality level required for diagnosis, on the basis of a determination image obtained by the emission of the radiation at the irradiation positions.

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 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.
