The present specification discloses a radiographic inspection system for screening an area. The inspection system has a container that defines an enclosed volume, a radiation source positioned within the enclosed volume, a detector array, a movable structure attached to a portion of the base of the container, and a controller programmed to move the movable structure to achieve an optimum height of the radiation source's field of view based upon a plurality of data.

A system for inspecting a moving person comprises an x-ray source, disposed in a fixed position with respect to the moving person, to generate one or more scanning x-ray beams. Each of the one or more x-ray beams being obliquely incident on either a front of the moving person, a rear of the moving person, or both. The system further comprises one or more backscatter detectors arranged to detect radiation scattered from the moving person, and to produce a detection signal therefrom. The system further comprises a processor and a memory with computer code instructions stored thereon. The memory is operatively coupled to the processor such that, when executed by the processor, the computer code instructions cause the system to produce a backscatter image based on the detection signal. When two or more x-ray beams are implemented, the two or more x-ray beams are temporarily interleaved to prevent crosstalk.

A sample inspection system contains a source of electromagnetic radiation and an apparatus that includes a beam former, a collimator and an energy resolving detector.
