Waste Crate and Container Imaging Using the Vehicle and Cargo Inspection System. Innovative Technology Summary Report
Description: The Vehicle and Cargo Inspection System (VACIS) is a highly penetrating gamma ray imaging system that provides a means to non-invasively image crate contents prior to crate disassembly. The VACIS unit uses a 1.6 Curie collimated source (Cesium-137) aimed at a linear detector to create an image as the unit passes by the crate. In the demonstrated mobile unit, the source and detector were mounted on a boom truck. As the crate passed between the source and detector, a near real-time composite image of the contents was constructed from the linear image of the VACIS unit's on board computer and recorded on disk.
