Abstract: In the radiographic imaging device, a portion of a second effective imaging region at a first side or a second side of a sensor unit of a second radiation detection panel, and a portion of a first effective imaging region at a third side or a fourth side of the sensor unit of a first radiation detection panel, are overlapped in a radiation irradiating direction. A portion of a second effective imaging region at the third side or the fourth side of the sensor unit of the second radiation detection panel, and a portion of a third effective imaging region at the third side or the fourth side of the sensor unit of the third radiation detection panel, are overlapped in the radiation irradiating direction. The second radiation detection panel is disposed at a side opposite the radiation irradiating section side of the first radiation detection panel and the third radiation detection panel.

Abstract: A mammography apparatus includes an imaging table; a radiation source; a stand; the compression plate including a bottom plate that compresses the breast and side plates provided on at least two locations of a subject side and a stand side of the bottom plate; and a projector that projects an image toward the compression plate and the imaging table, in which in a case where an intersection between an imaginary plane formed by extending the inner wall surface toward the projector and an imaginary horizontal line crossing the projector in a horizontal direction is defined as an imaginary intersection, an optical element closest to the compression plate on an optical path directed from the projector to the compression plate is located on the subject side with respect to the imaginary intersection.

Abstract: An electronic cassette has a configuration in which a first sensor panel and a second sensor panel are sequentially arranged in a thickness direction. The first sensor panel includes a first light detection substrate and a first scintillator. The periphery of the first scintillator is covered by a moisture-proof sealing layer. The sealing layer is made of a conductive material. The sealing layer is connected to the inner surface of a housing made of a conductive material through a connection portion. Therefore, the sealing layer has the same potential as the ground potential of the housing which is a reference potential and functions as a conductor layer.
