Abstract: A radiography system includes a mammography apparatus and a control device including a compression control unit that, in a case of performing continuous imaging in which the simple imaging and the tomosynthesis imaging are continuously performed while the breast being compressed by the mammography apparatus, performs control to cause a compression member to compress the breast at a first force in a first imaging of the simple imaging or the tomosynthesis imaging that is performed first in the continuous imaging, to change a force of the compression member compressing the breast from the first force to a second force lower than the first force after the first imaging, and to cause the compression member to compress the breast at the second force in a second imaging that is performed later.

Abstract: A radiography device includes: a radiation emitting unit that irradiates a subject with radiation at a plurality of different incident angles; a radiographic image generation unit that receives the radiation passed through the subject and generates a radiographic image; a part-of-interest detection unit that detects a mutation site suspected as a lesion from the radiographic image obtained by irradiating the subject with the radiation at a predetermined incident angle; and a radiography device control unit that controls whether to perform each of the tomosynthesis imaging in which the radiographic image generation unit generates the radiographic image while the radiation emitting unit changes the incident angle of the radiation and two-dimensional radiography in which the radiation emitting unit is fixed to a predetermined incident angle and the radiographic image generation unit generates the radiographic image, on the basis of a detection result of the part-of-interest detection unit.
