| 1. A system for detecting an explosive within an article, comprising:
an energy-discriminating acquisition subsystem including an x-ray computed tomography scanner having a stationary radiation
source and a stationary detector, said acquisition subsystem is adapted to acquire intensity measurements pertaining to the
explosive;
a means for conveying articles to be scanned through the computed tomography scanner; and
a reconstruction subsystem, in communication with the acquisition subsystem, for generating view data from the intensity measurements
and for reconstructing the view data into image data representative of the explosive, wherein said reconstruction subsystem
utilizes three-dimensional reconstruction techniques;
wherein the acquisition subsystem acquires image data of the articles for three-dimensional reconstruction without rotating
the articles.
