ABSTRACT:
A radiographic imaging system comprises: imaging unit including a radiation source for emitting radiation and a radiation detector for detecting radiation emitted from the radiation source and having penetrated a subject; moving unit for moving the imaging unit between a plurality of imaging positions that partially share an imaging region with each other; control unit for sequentially moving the imaging unit to the imaging positions with the moving unit, causing the radiation source to emit radiation to acquire a short image with the radiation detector in each imaging position, and acquiring a dark image with the radiation detector after acquiring the short image; and image processing unit for performing residual image correction upon the short image acquired in each of the imaging positions based upon the dark image acquired immediately before the acquisition of the short image and thereafter combining corrected short images to obtain a long radiographic image.
