INSPECTION SYSTEM AND SPATIAL RESOLUTION TECHNIQUE FOR DETECTING EXPLOSIVES USING COMBINED NEUTRON INTERROGATION AND X-RAY IMAGING

X-ray CT (computed tomography) and neutron interrogation (NI) are combined to provide an inspection system (100) and spatial resolution technique for detecting explosives. X-ray CT (510) is used to derive a physical density map of a bag (B). The density map from X-ray CT (510) and data from neutron...

Beschreibung
Zusammenfassung:	X-ray CT (computed tomography) and neutron interrogation (NI) are combined to provide an inspection system (100) and spatial resolution technique for detecting explosives. X-ray CT (510) is used to derive a physical density map of a bag (B). The density map from X-ray CT (510) and data from neutron interrogation (520) is used to generate three-dimensional maps of the chemical make-up of the bag (B) contents. Information from the X-ray CT procedure is also used to focus the neutron interrogation on particularly suspect regions of interest in the bag (B).
