Fusion is an advanced checkpoint system that combines computed tomography for material discrimination and automated explosives detection with high-resolution two- and three-dimensional imaging to scan for weapons and other prohibited items. Developed by Reveal Imaging Technologies, Inc., of Bedford, Massachusetts, in partnership with the U.S. Transportation Security Administration, the system is designed to efficiently screen carry-on items. The automated bin-return system delivers empty bins back to the front of the checkpoint for the net passengers. It is fully compatible with Reveal’s ImageNet multiplexing architecture, which allows security officers to be located at the scanner or centralized to improve flow at the end of the checkpoint.
