A digital fluorography apparatus includes an X-ray tube, an X-ray/photo converter, an imaging system, an image processing unit, a display, a comparing unit, a fluorographic control unit, an imaging control unit, and an X-ray tube control unit. The converter opposes the tube to sandwich an object therebetween. An X-ray image formed by the converter is sensed by the imaging system. The image processing unit directly outputs image data sensed by the imaging system in a fluorography mode, and performs predetermined digital image processing of the image data and then outputs the resultant image data in an imaging mode. The image data output from the image processing unit in the fluorography mode is compared with reference data by the comparing unit, and a fluorographic control signal corresponding to the comparison result is generated from the fluorographic control unit. The imaging control unit generates an imaging control signal corresponding to the control data from the fluorographic control unit. The X-ray tube is driven under the X-ray radiation conditions corresponding to the control signals. |
