Patent ID: 7235789

Claim:
A radiation image sensing apparatus comprising: a conversion unit that comprises a plurality of pixels which are arranged in a matrix, each pixel including a first conversion element and a switch element connected to the first conversion element on a substrate, wherein said conversion unit outputs a signal for image information in accordance with a dose of incident radiation, a second conversion element which is arranged, between the pixels in said conversion unit, on said substrate to generate a signal on the basis of at least any one of a dose of the incident radiation to said conversion unit, a radiation incident event to said conversion unit, and a radiation stop event, wherein said second conversion element has a different shape from that of the first conversion element; a first processing circuit unit which is connected to the pixels, which processes the signal to obtain the image information; and a second processing circuit unit which is separated from said first processing circuit unit and is connected to said second conversion element without being connected to the first conversion element, which processes the signal generated by said second conversion element.
