Paper Abstract

Imaging and visualization techniques for aircraft security are discussed. Planar transmission imaging techniques using x-rays and nuclear radiation are described along with their intrinsic limitations. Methods for distinguishing materials using dual - energy and multi-energy x-ray sources are shown along with techniques for simulating materials with mixtures of other materials. Tomographic reconstruction methods are derived and estimates made of their performance. X-ray diffraction imaging is shown as an alternative method to transmission measurements. Evaluation of overall system performance through the use of "receiver operator characteristics" (ROC) methods is discussed along with their application to evaluation of performance of screening systems.
