Abstract
This invention is directed towards finding, locating, and confirming threat items and substances. The inspection system is designed to detect objects that are made from, but not limited to, special nuclear materials (“SNM”) and/or high atomic number materials. The system employs advanced image processing techniques to analyze images of an object under inspection (“OUI”), which includes, but is not limited to baggage, parcels, vehicles and cargo, and fluorescence detection.

53. 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 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 positioned opposite said dual energy X-ray source, configured to receive dual energy radiation transmitted through said object, and adapted to generate signals, comprising a high energy data component and a low energy data component, based upon said 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. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)

69. 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 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 positioned opposite said dual energy X-ray source, configured to receive dual energy radiation transmitted through said object, and adapted to generate signals, comprising high energy data and low energy data, based upon said received dual energy radiation; at least one processor for processing said signals to generate a three dimensional image of said object, to locate a threat within said object, and to generate a signal comprising data defining said location; and a second stage inspection system comprising a radiation source and a detector array having at least one transmission detector or energy-dispersive detector, wherein said second stage inspection system inspects said object based on said location. - View Dependent Claims (70, 71, 72)
