In a method for correction of an image data set that was acquired with a planar image detector using at least two calibration images that were acquired in a preliminary procedure, as well as a method for generation of an image from a raw image data set that was acquired with a planar image detector with a high-sensitivity dynamic range and with a low-sensitivity dynamic range and which is composed of two image data sets, of which one was acquired in the high-sensitivity dynamic range and the other was acquired in the low-sensitivity dynamic range, at least two calibration images are generated in each dynamic range in a preliminary process. These calibration images are used in a correction procedure for the correction of the individual image data sets, as well as in a combination procedure to merge the two corrected image data sets into one image. In the combination procedure the two image data sets are conformed to one another using a comparison of the calibration images of the high-sensitivity dynamic range with the calibration images of the low-sensitivity dynamic range. The adjusted, corrected image data sets are added with weighting in a second step.
