Abstract
At least three radiation-detection views are used to facilitate identifying material as comprises an object being assessed along a beam path relative to that object. This comprises developing a first radiation-detection view (101) as corresponds to the material along the beam path, a second radiation-detection view (102) as corresponds to the material along substantially the beam path, and at least a third radiation-detection view (103) as corresponds to the material along substantially the beam path. At least one of the source spectra and detector spectral responses used for these radiation-detection views are different from one another for each view. One then uses (104) these radiation-detection views to identify the material by, at least in part, differentiating the material from other possible materials.
