Abstract
A first sensor panel, a second sensor panel, and a base are accommodated in a housing of an electronic cassette. Circuit substrates are mounted on a rear surface of the base. The base is made of a pitch-based carbon fiber reinforced resin obtained by impregnating a pitch-based carbon fiber with a matrix resin. The fiber directions of the pitch-based carbon fibers are aligned with one direction. Therefore, the base has high thermal conductivity in a direction parallel to the fiber direction. As a result, the driving heat of the circuit substrates is rapidly diffused to the entire rear surface.
Claims12
A radiographic image detection device comprising:
- a sensor panel in which pixels that accumulate charge in response to radiation, which has been emitted from a radiation source and transmitted through a subject, are two-dimensionally arranged;
- a circuit unit that converts the charge into a digital signal, outputs the digital signal as a radiographic image, and includes a plurality of circuit substrates on which various circuits are mounted;
- and
- a base that has a front surface to which the sensor panel is attached and a rear surface on which the circuit substrates are mounted and has anisotropic thermal conductivity in at least the rear surface.
