Abstract
A system and method for ascertaining the identity of an object within an enclosed article. The system includes an acquisition subsystem with a computed tomography machine and an alternate modality subsystem. The alternate modality subsystem includes a detector mounted to a rotatable gantry. The detector may be a quadrupole resonance unit, a dual energy x-ray unit, or a backscatter x-ray unit. The acquisition subsystem analyzes an article and distinguishes regions of interest (may contain contraband) from regions of no interest (do not contain contraband). The article is then transported to the alternate modality subsystem at which the detector further analyzes just the regions of interest.
