Abstract
Abstract A system and method for inspecting an object with transmitted and/or scattered penetrating radiation using either a fan beam or multiple pencil beams while maintaining resolution comparable to that achievable using a single scannable pencil beam. The system and method provide for spatial resolution of transmitted radiation using a fan beam or multiple pencil beams and a nonsegmented detector.
