Patent ID: 8841620

Claim:
A radiographic imaging device comprising: a plurality of pixels disposed in a matrix in a detection region for detecting radiation, each pixel comprising a sensor section that generates charges based on irradiation of radiation, or on illumination of light that has been converted from radiation, and a switch element connected to the sensor section, wherein the plurality of pixels includes a plurality of radiographic imaging pixels and a plurality of radiation detection pixels; a plurality of scan lines, connected to each of the switch elements, through which a control signal flows for switching the switch elements in order to read out the charges that has been generated in the sensor sections of each pixel, out of the plurality of pixels; a plurality of signal lines through which an electrical signal flows corresponding to the charges that has been accumulated in the sensor sections, and are connected to the sensor sections according to the switching state of the switch elements; and a cumulative radiation accumulation detection circuit connected to a plurality of the radiation detection pixels of the plurality of pixels in matrix in the detection region.
