RADIATION IMAGING APPARATUS AND RADIATION IMAGING SYSTEM
First Claim
1. A radiation imaging apparatus comprising:
- a plurality of pixels which are arranged in an array in an imaging region and which are for obtaining a radiation image;
a first detection pixel including a first switch element and a second detection pixel including a second switch element and having sensitivity to detection of a radial ray which is different from sensitivity of the first detection pixel which are used to obtain information on irradiation with a radial ray on the imaging region including at least one of a start of irradiation with a radial ray, an end of irradiation with a radial ray, intensity of irradiation with a radial ray, and an amount of irradiation with a radial ray;
a first signal line which is disposed in the imaging region or adjacent to the imaging region and which receives a signal supplied from the first detection pixel through the first switch element in a conductive state;
a second signal line which receives a signal supplied from the second detection pixel through the second switch element in a conductive state;
a reading circuit configured to perform a first operation of reading first and second signals which appear in the first and second signal lines in a state in which the first and second switch elements are in a non-conductive state while the radiation imaging apparatus is irradiated with a radial ray and a second operation of reading third and fourth signals which appear in the first and second signal lines when the first and second switch elements are brought into a conductive state; and
an information processing circuit configured to perform a process of generating the information based on the first to fourth signals.
