Abstract
The invention relates to a method of determining the Compton profile of an object to be examined which is situated in an examination zone. The examination zone is irradiated by a monochromatic primary beam whose energy is chosen so that the attenuation of the primary radiation is due essentially only to the Compton Scattering. The scattered radiation is measured in an energy resolving manner and therefrom, as well as from the attenuation in the primary beam, the Compton profiles for the individual pixels in the examination zone are determined.
