Abstract
The invention relates to a method of determining the share of different chemical elements in a layer of an examination zone. The Compton scattered radiation and the Rayleigh scattered radiation are separately determined and the variation of the differential scatter coefficients derived from the measurement values is influenced by the shares of the various chemical elements contained in the individual pixels. Therefore, the share of these chemical elements can be determined therefrom.
