IHI installed large container X-ray inspection systems at the Osaka and Kobe customs in February 2002, and at Tokyo, Nagoya and Moji customs in February 2003. The system can inspect export and import cargoes according to the customs law. The purpose is to detect and expose illegal entrants as well as illegal and undeclared cargoes in the container and so on according to the analytic information of the X-ray image. The system can carry out more efficient inspection compared to the conventional open check of cargoes, because the system can acquire an image of the whole container diorama. The outline of the system is described.
