Abstract
An X-ray device for scanning objects moving on a conveyor path and for processing the detector signals acquired by the scan has a comparator for identifying faulty signals, the comparator being in a control chain for an image storage memory such that, in the event of a faulty detector signal, the contents of a memory row preceding the faulty detector signal are transferred into the memory row into which the faulty detector signal, if a correct signal, would have been stored. The system also includes a correction element for generating a reference signal at 100% radiation intensity in which the mean value of a number of measured signals is formed. The system also includes an element for reducing the amplitude of the useful signal during measurement in comparison to the amplitude allocated to a radiation intensity of 100%.
