Abstract
In a method for the operation of a digital imaging system of an X-ray diagnostic apparatus having an X-ray unit for the generation of X-ray images, an X-ray image converter-television chain for the acquisition of the X-ray images, the chain including a digital image converter having image points arranged in matrix form in rows and columns and a monitor for the reproduction of the X-ray images processed by the digital imaging system. Defective image points are recognized by converting at least one calibration image into a filter image by highpass filtering, e.g. a median filtering, and the filter image is subjected to defect determination, so that a defect image is obtained. The defect image is used for the correction of an original image.
