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