Abstract: Body scanners are used in airports and other secured facilities to detect weapons, explosives, and other security threats hidden under persons' clothing. These devices use x-rays, millimeter waves and other radiant energy to produce an electronic image of the person's body and any concealed objects. Examination of these images by human analysts is slow, expensive, and subject to privacy concerns. The Invention provides automated analysis by comparing each image against a database of previous scans, using a plurality of subjects with different body types. This comparison is facilitated by digitally mapping each body scanner image to humanoid coordinates. This overcomes the failings of the prior art by allowing each anatomic location on one person to be referenced to the same anatomic location on all other persons.
