Patent ID: 7912261

Claim:
A method for correcting a raw X-ray image of a digital X-ray detector including an active pixel matrix with pixel readout elements, the matrix including at least two detector plates, the method comprising: at least one of 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, and preparing, 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, new correction values for the pixel readout elements of at least one detector plate; and carrying out a correction of the raw X-ray image with at least one of the changed correction values, and the original correction values and the new correction values, wherein the deviation is reduced by carrying out a normalization of correction values of a correction image, and a further correction image is divided electronically in pixel-wise fashion by the normalized correction image.
