|Applicants:||CANON KABUSHIKI KAISHA
|Title:||RADIATION IMAGING DEVICE, RADIATION IMAGING SYSTEM, RADIATION IMAGING DEVICE CONTROL METHOD, AND PROGRAM|
A radiation imaging device provided with: an imaging region in which a plurality of conversion elements are disposed; a control unit; and a storage unit. The plurality of conversion elements include a first conversion element for acquiring a radiation image, and a second conversion element for acquiring irradiation information about incident radiation during irradiation. Correction data for correcting a signal output from the first conversion element are stored in the storage unit. The control unit, in accordance with the irradiation information: determines a period in which to cause the first conversion element to perform an accumulation operation; determines from the correction data a correction amount corresponding to the period; and, after irradiation, corrects the signal output from the first conversion element in accordance with the correction amount and generates a signal for a radiation image.
