RADIATION IMAGING DEVICE, RADIATION IMAGING SYSTEM, AND RADIATION DETECTION PROGRAM

摘要

A plurality of sensor units (146) that detect radiation respectively applied to the image pickup regions of a radiation detector (60) are disposed such that the sensor units overlap the image pickup regions, said radiation detector picking up radiation images formed by radiation applied to the image pickup regions, and at least two out of radiation application start, radiation application end, and applied radiation quantity are detected by separately using the sensor units (146). Consequently, while suppressing deterioration of the qualities of the whole picked up image, at least two out of the radiation application start, radiation application end, and applied radiation quantity can be detected.
