Abstract

The mathematical model of an output digital signal from a single measuring channel of a scanning digital X-ray imaging system containing a line of detectors is presented for the case where the main type of signal distortions is the noise due to the quantum nature of radiation. This model is used to develop a one-dimensional algorithm for the automatic detection of local "critical" inclusions in an inspected object and to obtain the statistical estimates of its efficiency based on a model example.
