X‐Ray Cargo Inspection: Status and Trends

Gongyin Chen; Paul Bjorkholm; Timothy R. Fox; Zane Wilson; Xavier Bonsergent

Over the past several years, x‐ray cargo inspection has experienced tremendous growth. There are several hundred systems in use world wide and a few new units are installed every week. Fielded systems are mostly located in north and West Africa, Middle East, Europe (especially Russia), East Asia, and South America. The majority of systems are powered by Varian M3, M6 or M9 Linac x‐ray sources. The spatial resolution of these systems is typically 3–5 mm, penetration ranges from around 200 mm to 450 mm of steel and contrast sensitivity is typically 1–4%. Inspection throughput ranges from about 20 trucks per hour to 200 trucks per hour. Currently the systems are primarily used to fight import tax evasion and smuggling of controlled substances. There are a few clear trends: Imaging performance has been steadily improving; a variety of systems have been developed to fit different needs; also, there is a strong effort in material discrimination, or even identification and automatic detection. The last, but not ...
