Body Scanner with Reference Database
First Claim
1. A method for performing automated target recognition on a body scanner, comprising:
- acquiring database scans;
converting said database scans to humanoid coordinates;
acquiring subject scan;
converting said subject scan to humanoid coordinates;
comparing said subject scan to said database scans;
identifying features in said subject scan that appear infrequently in said database scans.

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.
