ABSTRACT:
In flat-panel X-ray detectors which have a multiplicity of detector elements which are in each case associated with one pixel of an X-ray image, the individual detectors generate offset signals. These offset signals are detected by recording offset images in which there is no X-ray irradiation (dark images). The offset images are recorded after the X-ray images to be corrected in time. If for each X-ray image record, an associated offset image record is generated by using a single offset image or of two, the offset images can be recorded closely in time. Ghosting effects are then not disturbing because the offset images are only used for correcting the X-ray images which cause the ghosting.
