摘要：
For the comparatively simple and precise correction of an X-ray image (RB) recorded by a digital X-ray detector (3) with comparatively little calibration, at least one gain image (G0,G1,G2) is selected from a plurality of stored gain images (G) for linking to the X-ray image (R) based on at least one parameter (Pi) characterizing the recording conditions of the X-ray image (RB), whereby the gain images (G) are stored such that they differ at least in respect of one parameter (Pi) used for the selection and whereby the selection of the at least one gain image (G0,G1,G2) is made based on the distance (d) between the parameter configuration (g0,g1,g2) of the gain image (G0,G1,G2) and the parameter configuration (p) of the X-ray image (RB) in a parameter space (35) set by the parameters (Pi).
