Abstract
The present application discloses a system for scanning a shoe for illegal materials. The system includes an X-ray source for projecting a beam of X-rays onto the shoe, a detector array for detecting X-rays transmitted through the shoe and at least one metal detector coil for detecting metals within the shoe. The system produces a radiographic image of the shoe by processing the detected X-rays and data obtained from the at least one metal detector coil. Other embodiments are directed toward other screening technologies, including millimeter wave screening technologies.
