ABSTRACT:
A radiographic apparatus according to this invention stores, before an imaging event, offset images and gain correcting images corresponding to a plurality of storage times, and acquires a lag image and a radiographic image based on these stored images. Then, lag correction is carried out to remove lags, using the lag image, from the radiographic image. In this way, from the radiographic image taking into consideration the offset images and gain correcting images corresponding to the storage times, lags are removed using the lag image which similarly fakes into consideration the offset images and gain correcting images corresponding to the storage times. Lag-behind parts, including offset and gain components, are removed from radiation detection signals in a simple way.
