Title:
RADIATION IMAGING DEVICE, RADIATION IMAGING SYSTEM, CONTROL METHOD FOR RADIATION IMAGING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/198491
Kind Code:
A1
Abstract:
Provided is a radiation imaging device that comprises: an imaging region in which a plurality of conversion elements are disposed, the conversion elements used in an imaging operation for obtaining a radiation image in accordance with incident radiation; a detection element that detects the radiation amount of the radiation incident in the imaging region; a reading unit; and a control unit. The control unit: corrects a detection signal read out from the detection element by the reading unit during incidence of the radiation in a second imaging operation performed subsequent to a first imaging operation on the basis of a correction amount obtained on the basis of a correction signal read out from the detection element by the reading unit after the completion of incidence of the radiation in the first imaging operation; and detects the amount of radiation incident in the second imaging operation on the basis of the corrected detection signal.
