    Abstract: Provided are a radiography device, a radiography method, and a radiography program which can obtain an accurate radiographic image while reducing a burden on a subject. A radiography device control unit determines imaging conditions including at least one of resolution or an incident angle range, on the basis of a radiographic image captured before tomosynthesis imaging, and performs tomosynthesis imaging. Specifically, the radiography device control unit controls tomosynthesis imaging (120) such that tomosynthesis imaging is performed under first conditions (108) of low resolution and a narrow incident angle range in a case in which a mutation site suspected as a lesion is not detected and tomosynthesis imaging is performed under second conditions (112, 116, and 118) which are different from the first conditions in at least one of the resolution or the incident angle range in a case in which the mutation site suspected as a lesion is detected.

    Abstract: A radiation image capture device includes plural radiation detection panels that each detect incident radiation that has passed through an imaging subject, that each generate a radiation image, and that are disposed in a row in a direction orthogonal to the radiation incident direction. The radiation image capture device designates a display target image from out of plural radiation images respectively generated by the plural radiation detection panels, and transmits the designated display target image to a console. At least a radiation image other than the display target image is stored in an image memory. The console displays on a display section the received display target image and, in response to data indicating a display request for a radiation image other than the display target image, also displays on the display section the radiation image other than the display target image read from the image memory.

    Abstract: A chamfered portion configured to have a surface which is tilted to a side surface and a rear surface is formed between the side surface and the rear surface of a housing of an electronic cassette. The chamfered portion has a boundary portion having a predetermined range in the vicinity of a boundary including the boundary with the side surface; a boundary portion having a predetermined range in the vicinity of a boundary including the boundary with the rear surface, and the other portion which does not belong to these boundary portions. The chamfered portion needs to be smoothly inserted into a gap between a patient and an installation surface on which the patient lies on one's back. Therefore, an entire surface of these boundary portions is formed in a curved surface which protrudes outward from the housing.

    Abstract: A radiation detector includes a sensor panel unit, a support table to which the sensor panel unit is attached, and two fixing members. The sensor panel unit includes two sensor panels. The sensor panel has pixels that sense visible light converted from radiation and generate charge. The sensor panel unit has a configuration in which an end portion of one sensor panel and an end portion of the other sensor panel are arranged to overlap each other in a thickness direction. A first fixing member fixes two sensor panels in an overlap region in which the end portions overlap. A second fixing member fixes the sensor panel unit and the support table in the overlap region. The second fixing member at least partially overlaps the first fixing member in the overlap region in a plan view of the sensor panel unit in the thickness direction.
