Primary Screening for Carry-On Baggage Fact Sheet

Body

The DHS Science and Technology Directorate (S&T) Primary Screening for Carry-On Baggage project develops technology solutions to solve problems for TSA by developing modular, dynamically upgradable screening systems to improve detection capabilities and increase passenger throughput, while improving life cycle costs. This project delivers new carry-on baggage screening systems in full-size and reduced form factors to meet the needs of all sizes of airports and to be compatible with TSA standards and systems. Systems are also being developed with Automatic Threat Recognition (ATR) for explosives and other prohibited items to reduce the false alarm detection rates. Technologies under development include Computed Tomography (CT) based X-ray systems, secondary hybrid systems to resolve alarms, and synthetic data generation for algorithm training.
