  • Automatic concealed object detection system having a pre-scan stage
    Patent number: 5182764
    Abstract: An apparatus for detecting concealed objects, such as explosives, drugs, or other contraband is disclosed. The apparatus uses CT scanning to identify concealed objects with a density corresponding to the density of a target object such as explosives or drugs. To reduce the amount of CT scanning required, a number of prescanning approaches are disclosed. Based upon the prescan data, selected locations for CT scanning are identified. CT scanning is undertaken at the selected locations. The resultant CT scan data is utilized to automatically identify objects of interest. This identification of objects may be verified through further automatic analysis of such attributes as shape, texture, and context. Finally, the objects of interest may be reconstructed and displayed on a computer monitor for visual analysis by an operator.
