ABSTRACT:
In a method to create a gain-corrected x-ray image with the aid of a flat-panel x-ray detector a number of gain images are determined on calibration and this is done for different measurement situations which correspond to different settings of specific x-ray imaging variables such as the angle of the flat-panel x-ray detector to an x-ray tube, the energy of the x-radiation used etc. Instead of the usual gain image for each element of the detector, a gain value is then used in the gain correction which is produced from an interpolation of the corresponding values from the number of gain images.
