ABSTRACT:
In the radiographic apparatus according to this invention, when a radiographic mode designator16designates a non-standard radiographic mode, a signal corrector15uses defect information stored in one of non-standard image defect information memories18B–18E for correcting X-ray detection signals outputted from an FPD2.Since the pixel defect information for non-standard X-ray images is acquired by a pixel defect information converter19through a conversion from defect information for standard X-ray images stored in a standard image defect information memory18A, it is unnecessary to collect output signals for pixel defect information acquisition from the FPD2all over again. As a result, abnormal X-ray detection signals due to defects of radiation detecting elements may be corrected promptly, regardless of how the radiation detecting elements are assigned to the pixels in the X-ray images.
