Abstract:
A method for operating an image system of an imaging medical examination device, the image system having a reception unit for receiving a plurality of signals arising at different locations and a display unit for an image of pixels, the pixels each being assigned at least one signal, the method comprising the steps of:automatically triggering, with a triggering event generated at a defined point in time after an image acquisition procedure, a defect determination for determining a defective pixel in the image and, after the defect determination, automatically triggering a correction process if a defective pixel was detected, wherein the defect determination and the correction process comprise the steps of carrying out a first correction in which already known defects are corrected using an old defect map, analyzing the results of the first correction process to create a new defect map that describes new defects not found in the old defect map, and carrying out a second correction in which the new defects are corrected using the new defect map.
