The handheld LEXID® X-ray imaging device provides a quick and safe way for Homeland Security personnel, law enforcement, customs and border agents, and Coast Guard boarding parties to view concealed objects and potential threats behind walls, or hidden in containers or vehicles. LEXID® is a single sided X-ray detection and imaging system that provides through-the-wall acquisition and focusing of Compton backscattered photons of hidden objects, contraband, explosive devices, weapons or people. The hard X-ray optics combined with the X-ray detector significantly lowers the exposure dose, while greatly enhancing image resolution. The real-time operating LEXID® software synchronizes images acquired, then processes and displays them on the liquid crystal display. POC can currently demonstrate images through a car door with 4mm resolution. Future systems will have improved resolution, X-ray source and X-ray imaging.
