Abstract
A radiographic apparatus removes lag-behind parts from radiation detection signals taken from an FPD as X rays are emitted from an X-ray tube, on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of exponential functions, N in number, with different attenuation time constants. The lag-behind parts are removed by using impulse responses corresponding to variations in the sensor temperature of the FPD. X-ray images are created from corrected radiation detection signals with the lag-behind parts removed therefrom.
