Abstract:
A radiation imaging apparatus includes: a radiation detection unit including an image obtaining pixel for obtaining a radiation image and a dose obtaining pixel for obtaining a radiation dose; a generating unit configured to generate calibration data for calibrating an output value of the dose obtaining pixel by comparing an output value of the image obtaining pixel and the output value of the dose obtaining pixel; and a calibration unit configured to calibrate the output value of the dose obtaining pixel by using the calibration data.
