| abstract |
In exemplary embodiments of the present invention, containers, such as, for example, those used in transportation and shipping, can be inspected by using a CT X-ray scanning system with a large area detector plate. In exemplary embodiments of the present invention the detector plate can directly convert X-rays transmitted through the container into visible light, thus forming light patterns on the outer surface of the plates. The plates can then be analyzed using, for example, CCD or ICCD cameras and a data processor so as to form real-time 2D and/or 3D images of objects in the container. In exemplary embodiments of the present invention each such plate can comprise a coating of X-ray converting material such as, for example, a phosphor on a metallic plate. In exemplary embodiments of the present invention an exemplary scanning system can, for example, rotate a rotor having an X-ray source on one side of an axis of rotation, and a detector including such detector plates on the other side of the axis. In exemplary embodiments of the present invention a container can be moved, through an opening in the rotor and support structure in synchronization with the rotor, such as, for example, by transporting the container on rails. |
