Paper Abstract

Through the use of dual-energy CT, it is possible to obtain a two-dimensional mapping of average electron density and average atomic number within the imaged plane. Preliminary results obtained with medical scanners indicate that these data may provide a reliable criterion for differentiating between explosives and innocent materials contained within a package or suitcase without resorting to imaging, pattern recognition, or operator interpretation. The results of a preliminary systems study indicate that a practical system based on this principle of detection is feasible. Currently, there is a program for the development of a breadboard dual-energy Cm explosives detection system tailored to meet the performance characteristics reauired for a checkpoint operational scenario.
