DUAL ENERGY COMPUTED TOMOGRAPHY FOR CHECKED BAGGAGE SCREENING
[chapter]
2009
Handbook of Pattern Recognition and Computer Vision
Single energy computed tomography (CT) scanners use measurements of densities to detect explosives in luggage. It is desirable to apply dual energy techniques to these CT scanners to obtain atomic number measurements to reduce false alarm rates. However, the direct application of existing dual energy techniques has practical problems, such as, approximation errors and lack of boundary constraints in dual energy decomposition, image artifacts, and x-ray spectral drifts. In this paper, we present
