Description

The interaction of an x-ray beam from a conventional generator with an object containing more than one type of material is a very complicated process. The shape of the bremsstrahlung spectrum from the generator depends on the target material and orientation, as well as on the inherent filtration and any additional filters through which the beam passes. Absorption of the beam in the part under study varies dramatically with energy and depends critically on the atomic number and density of the material. Thus, interaction of x-rays in an object can provide a great deal of information about the elemental composition of the part. However, this information is difficult to extract from data obtained using a bremsstrahlung spectrum.
