The inventive body scanner is used to screen persons entering a security controlled area for the presence of security threats hidden under the clothing, such as guns, knifes, explosives and contraband. The Invention is an improvement on prior art body scanners that operate primarily by acquiring backscatter x-ray images, but only acquire transmission images over a limited part of the person's body. These prior art systems provide x-ray sources on the anterior and posterior sides of the person being screened, and x-ray sensitive detectors on the sides of these x-ray sources. While sufficient for backscatter imaging, the gaps between these detectors results in blind areas in the transmission images, resulting in lower ability to detect security threats hidden under the clothing. The present Invention overcomes these limitations of the prior art by providing x-ray sensitive detector on the outside of the x-ray sources. That is, the pair of x-ray sources are located within the pair of x-ray detectors, and the person being screened is located within the pair of x-ray sources. In conjunction with this imaging geometry, spatial offsets in the location of the x-ray sources provide effectively full transmission coverage for transmission imaging.

The inventive shoe scanner is used to screen persons entering a security controlled area for the presence of security threats hidden within their shoes, such as guns, knifes, explosives and contraband. In one embodiment the person being screened stands on a base assembly containing a flying spot x-ray source and detector. X-rays produced by the x-ray source irradiate the person being screened from below their feet, resulting in a backscatter signal being produced by the detector. This detected signal is converted into a digitally represented image and examined by a security officer, allowing detection of any hidden objects. In another embodiment, x-rays that are transmitted through the person's feet are detected by an x-ray detector positioned above the base assembly, and the resulting signal converted into another digitally represented image for display to the security officer. The shoe scanner may be used alone, or as part of a more comprehensive body scanner, such as scanning of the person's front and rear using backscatter and/or transmission x-ray imaging.
