ABSTRACT:
The transmitted polychromatic x-ray beam in a cross-sectional x-ray imaging system is applied to pulse-height discriminators for energy spectral analysis. Various regions of the energy spectrum are separately counted in order to provide an accurate reconstruction of the cross-sectional density which is independent of the different materials in the path of the transmitted x-ray beam. This same energy spectral information is used to create separate images representing the different materials in the cross section.
