RADIATION IMAGING DEVICE AND RADIATION IMAGING SYSTEM

WIPO Patent Application WO/2018/135293

A1

The present invention includes: a first pixel for detection that includes a first switching element and a second pixel for detection that includes a second switching element and the sensitivity of which to detect radiation is different from that of the first pixel for detection; a first signal line to which a signal is outputted via the first switching element in an electrical continuity state and a second signal line to which a signal is outputted via the second switching element in an electrical continuity state; a readout circuit for performing, while the radiation imaging device is irradiated with radiation, a first operation for reading out a first and a second signal appearing on the first and second signal lines when the first and second switching elements are not in the electrical continuity state and a second operation for reading out a third and a fourth signal appearing on the first and second signal lines due to the fact that electrical continuity is established between the first and the second switching elements; and an information processing circuit for performing a process of generating information relating to radiation irradiation on the basis of the first to fourth signals.
