Description

The use of two or more radiographs of an object taken with different x-ray spectral characteristics to infer quantitative values of material density or Z number has been of interest to both the medical and industrial worlds for some time. One method uses monoenergetic isotopic sources with well defined energies in conjunction with standard step wedges and solving the resulting simultaneous equations. Besides the problem of finding isotopic sources with the appropriate energies, you have to have a priori knowledge of the materials in the object.
