Abstract
A method is disclosed for operating a flat detector in different dose ranges and at different amplifier levels. A previously measured detector sensitivity is respectively used for the calibration. The detector sensitivity is determined for each amplifier level at a multiplicity of different points in the overall gain-specific dose range. Further, a calibration value of the previously measured neighboring values is used in order to calibrate a measurement image for a predetermined dose.
