1. An apparatus for identifying an object concealed within a container, comprising:
- a first stage inspection system having a scanning system to generate a first set of data;
a plurality of processors in data communication with the first stage inspection system wherein the processors process said first set of data and wherein the first set of data is used to identify at least one target region;
a means for positioning an inspection region relative to the target region wherein an inspection region at least partially physically coincides with the target region; and
a second stage inspection system for generating the inspection region wherein the second stage inspection system produces a second set of data having an X-ray signature characteristic of the material in said inspection region and a third set of data having an fluorescence signature characteristic of the material in said inspection region.

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.

30. A method for identifying an object concealed within a container, comprising:
-
generating a first set of data using a first stage X-ray inspection system; processing said first set of data using a plurality of processors in data communication with the first stage inspection system; identifying at least one target region from said processed first set of data; positioning an inspection region relative to the target region wherein the inspection region at least partially physically coincides with the target region; generating the inspection region through a second stage inspection system; and producing a second set of data having a X-ray signature characteristic of the material in the inspection region and a fluorescence signature characteristic of the material in the inspection region. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A device for inspecting high atomic number material located within a target object using a radiation source, comprising:
-
a first member having detector electronics and a diffraction detector head; a second member affixed substantially perpendicularly to the first member; a third member affixed substantially perpendicularly to the second member and parallel to the first member, wherein the third member comprises a radiation source for projecting an X-ray beam toward the target object and comprises a fluorescence detector head; and a conveyor for positioning said target object between said first member and said second member. - View Dependent Claims (51, 52)
