20140050378 | SYSTEM AND METHOD FOR DETECTING MATERIALS OR DISEASE STATES USING MULTI-ENERGY COMPUTED TOMOGRAPHY - The disclosed embodiments relate to characterizing or quantifying an element or composition of interest within an imaged volume. In accordance with one embodiment, high and low energy images are acquired of a volume of interest using a polychromatic emission source. The high and low energy images are processed to generate monochromatic images. Based on the observed attenuation within the monochromatic images, one or more elements or compositions of interest are characterized within the imaged volume. | 02-20-2014 |
