摘要： A radiation detector includes a support table in which an attachment surface having an arc surface shape is formed, a sensor panel which has a rectangular plate shape and in which pixels that include TFTs and detect radiation are two-dimensionally arranged, a circuit board, a flexible cable, and a reduction structure. The sensor panel is attached to the attachment surface while being curved following the arc surface shape. The flexible cables connect a curved side of the sensor panel and a reading circuit board and are arranged along the curved side. The flexible cable is bent to dispose the reading circuit board at an angle of 90° with respect to the sensor panel. The reduction structure reduces a bias of a stretching force applied to the flexible cable caused by the curved side.

摘要： 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.
