Abstract:
1. An apparatus for inspecting an object, comprising: a first stage inspection system comprising a conveyor for transporting the object into a first inspection volume, a first X-ray source and a second X-ray source, wherein the first and second X-ray sources are positioned such that X-ray projections from the first X-ray source and X-ray projections from the second X-ray source mirror each other relative to a central vertical plane and wherein at least one of the first X-ray source and second X-ray source is a dual energy X-ray source wherein said dual energy X-ray source is configured to irradiate said first inspection volume with dual energy radiation, and a detector array configured to receive radiation from both the first X-ray source and second X-ray source transmitted through said object, and adapted to generate signals, comprising a high energy data component and a low energy data component, based upon received dual energy radiation; a second stage inspection system configured to inspect a second inspection volume, wherein said second inspection volume is smaller than the first inspection volume; and at least one processor for processing said signals to generate a three dimensional image of said object and to locate a threat within said object.
