On September 13, 2016 , the USPTO issued U.S. Patent Number 9,442,213 to RAPISCAN SYSTEMS, INC., which was successfully prosecuted by Novel IP.
The '213 patent is directed towards 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, an electron beam generated by a single radiation source is steered by an electron beam transport mechanism comprising at least two dipoles and a quadrupole on to a target arranged in an approximated arc. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.
Independent Claim 1 describes " An inspection system for generating a plurality of scanning views of an object under inspection, comprising: a source for generating at least one high-energy electron beam; a first set of magnets for directing the at least one electron beams into an electron beam transport system; the electron beam transport system comprising at least two electron beam transport stations, for directing said at least one electron beam to more than one target, wherein said more than one target produces radiation beams for scanning the object; at least one second set of magnets to maintain the at least one electron beam in a desired trajectory; at least one detector array for detecting said radiation and generating said plurality of scanning views; a transport mechanism to move the object through the system; and a processor for reconstructing tomographic images by combining said plurality of scanning views.
