Abstract:
1. A method to facilitate identifying material as comprises an object being assessed along a beam path, relative to the object, comprising: developing a first radiation-detection view as corresponds to the material along the beam path using a first interlaced-energy x-ray pulse and a first detector of a stacked detector; developing a second radiation-detection view as corresponds to the material along substantially the beam path using the first interlaced-energy x-ray pulse and a second detector of the stacked detector, wherein the second detector has a different spectral response than the first detector; developing at least a third radiation-detection view as corresponds to the material along substantially the beam path using a second interlaced-energy x-ray pulse and the first detector of the stacked detector, wherein the second interlaced-energy x-ray pulse has a different source spectra as compared to the first interlaced-energy x-ray pulse and wherein additional radiation-detection views may be developed but without using additional interlaced-energy x-ray pulses having a different source spectra as compared to the first and second interlaced-energy x-ray pulses; using the first, second, and third radiation-detection views to identify the material by, at least in part, differentiating the material from other possible materials.
