Multi-View Cargo Scanner
First Claim
1. An inspection system for generating an increased number of scanning views of an object under inspection, comprising:
- a source for generating a high-energy electron beam;
an electron beam steering system comprising a plurality of steering devices, for directing said electron beam to a corresponding plurality of production targets, said production targets generating radiation that scans the object;
a plurality of detector arrays that detect said radiation to produce a corresponding plurality of scanning views; and
a transport mechanism to move the object through the system.

Abstract
The present invention provides a multi-view X-ray inspection system. In one embodiment, a beam steering mechanism directs the electron beam from an X-ray source to multiple production targets which generate X-rays for scanning which are subsequently detected by a plurality of detectors to produce multiple image slices (views). The system is adapted for use in CT systems. In one embodiment of a CT system, the X-ray source and detectors rotate around the object covering an angle sufficient for reconstructing a CT image and then reverse to rotate around the object in the opposite direction. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.

10. A Computed Tomography (CT) system for scanning an object, comprising:
-
a high-energy X-ray source; at least one detector subsystem placed opposite to said high energy X-ray source and configured to move along with said high energy X-ray source around the object in an arcuate trajectory; and a transport mechanism to move the object through the system, wherein said source and said at least one detector subsystem in each scanning step rotate an angle around the object then reverse to rotate around the object in the opposite direction in a subsequent scanning step. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
