Patent ID: 8223922

Claim:
A radiation detection device that detects radiation in a plurality of energy ranges transmitted through a subject to which radiation is irradiated from a radiation source, comprising: a first detector that detects radiation in a first energy range that is transmitted through the subject to generate first radiation image data; a second detector arranged in parallel to the first detector with a predetermined region sandwiched therebetween, which detects radiation in a second energy range that is transmitted through the subject to generate second radiation image data; and a timing control section that controls detection timing of at least the second detector, based on a width of the predetermined region, so that first radiation image data to be generated by the first detector and second radiation image data to be generated by the second detector mutually correspond, wherein the timing control section controls the detection timing of at least the second detector, based on a magnification ratio being a ratio of a distance between the radiation source and the subject to a distance between the radiation source and the first detector or the second detector, and a conveying speed at which the subject passes through the predetermined region.
