摘要： Provided is a method for manufacturing a housing of a radiation detection cassette that can appropriately form a recess without a housing material depositing on an end mill or the like, in a case where a recess is formed by working the housing material formed of an alloy containing Mg and Li. A method for manufacturing a housing of a radiation detection cassette that houses a radiation detector in the housing includes preparing a housing material that is formed of an alloy containing Mg and Li and contains 0.1 mass % or more of Li, forming a recess using a working method other than cutting work on a surface of the housing material, and performing cutting work on the formed recess to shape the recess.

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.

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 CT apparatus includes an annular frame that rotates around a subject positioned in a bore, three columns that hold the frame to be rotatable and movable up and down in a vertical, an elevation mechanism that moves up and down the frame, and a rotation mechanism that rotates the frame. A radiation source and a radiation detector are attached to the frame at positions facing each other. The frame has a width smaller than a width of the radiation source and the radiation detector in a height direction over a whole periphery. An imaging controller performs control for operating the elevation mechanism in response to a return instruction from an operator to move the frame to a retreat height position set at a position of a highest point in an elevation range of the frame on an upper end side of the columns. The imaging controller performs control for operating the rotation mechanism in response to the return instruction from the operator to rotate the frame to a position of 60° that is a first rotation position where the radiation source overlaps the columns.

摘要： A radiation detector includes a support table, a sensor panel, a fixing member, and a contact member. An attachment surface having an arc surface shape is formed in the support table. The sensor panel has an imaging region in which a plurality of pixels detecting radiation are two-dimensionally arranged. A first surface of the sensor panel is attached to the attachment surface following the arc surface shape. The fixing member partially fixes the first surface to the attachment surface. The contact member comes into contact with a second surface of the sensor panel which is opposite to the first surface to suppress the lifting of the sensor panel from the support table.
