Patent ID: 7702068

Claim:
A system for detecting a barrel of a weapon in a container, the system comprising: a CT scanner operative to perform a CT scan of a container; a conveyor for advancing a container through the CT scanner; a host processor in communication with the CT scanner and operative to receive CT data from the CT scanner; and a detection processor in communication with the host processor and operative to: reconstruct slice data; analyze the slice data to determine if at least one of a hollow circular shape and an oval shape of a known diameter exists, the shape being surrounded by metal or dense plastic; if the shape does not exist, then determine if the detection processor has analyzed the last slice for the container; if the detection processor has not analyzed the last slice for the container, then analyzing the next slice to determine if at least one of a hollow circular shape and an oval shape of a known diameter exists, the shape being surrounded by metal or dense plastic; and if the detection processor has analyzed the last slice for the container, then determining that no weapon was found in the container.
