ABSTRACT:
A high-energy X-ray inspection system comprises an X-ray source for generating high energy X rays for inspecting the contents of large objects. The source is contained within an enclosure having an integrally-formed precollimator device that limits the radiation emitted from the source to form a "fan-beam" of X rays. A novel rotating cylindrical collimator converts the fan-beam into a pencil-beam of X rays, which is further limited by a fixed-slit collimator. The high-energy pencil-beam penetrates the entire area of an object and is intercepted by a detector, which transforms the X rays into image data for presentation on a display screen.
