ABSTRACT:
In order to ensure the preparation of an undistorted X-ray image of an examination image by an X-ray detector including an active pixel matrix with at least two detector plates, a method is provided. In at least one embodiment, a method for correcting a raw X-ray image includes changing, as a function of a deviation between correction values from pixel readout elements of a first detector plate and correction values from pixel readout elements of at least one further detector plate, the correction values of pixel readout elements of at least one detector plate, or preparing new correction values for the pixel readout elements of at least one detector plate. Further, the method in at least one embodiment includes carrying out a correction of the raw X-ray image with the changed correction values, or a carrying out a correction with the original correction values and the new correction values.
