Abstract:
1. An inspection system for inspecting footwear of an ambulant shod person, the system characterized by a first side and an opposing side, the system comprising: a. a source of penetrating radiation mounted on the first side of the system for providing a fan beam of penetrating radiation contained in a substantially vertical plane that traverses at least one foot of the ambulant shod person during the course of walking and exposes each foot to a dose of penetrating radiation of no more than 25 μR; b. a collimated linear array of photon-counting detectors disposed on the opposing side of the system for detecting penetrating radiation that has traversed the footwear of the ambulant shod person and generating a transmission signal; and c. a segmenting module implemented in software on a controller for identifying anomalies in the footwear of the ambulant shod person on a basis of the transmission signal.
