PROBLEM TO BE SOLVED: To provide a technique of correcting cross-talk between the pixel and the wire and variation of the characteristic of the pixel caused by temperature variation under operation, thereby enhancing accuracy of detection of radiation.SOLUTION: A radiation imaging device includes plural pixels arranged in an array form in an imaging area, a first detection element and a second detection element that contain plural pixels for converting radiation into an electric signal, a first signal line for outputting a signal from the first detection element, a second signal line for outputting a signal from the second detection element, and a signal processing circuit for processing a signal output from the first detection element via the first signal line and a signal output from the second detection element via the second signal line. The first signal line and the second signal line are arranged in an imaging region or to be adjacent to the imaging region. The first detection element has a larger area for detecting radiation than the second detection element. The signal processing circuit generates information on irradiation of radiation based on the signal from the first signal line and the signal from the second signal line.SELECTED DRAWING: Figure 1 |
