Innovation & Technology

The Transportation Security Administration (TSA) was founded after the attacks of September 11, 2001 to protect our nation's transportation systems and keep the traveling public safe. At TSA, the testing and use of emerging technology is critical to achieving that mission and staying ahead of known threats to transportation security.

Since 2007, TSA piloted state-of-the-art advanced imaging technologies that can detect a wide range of threats to transportation security in a matter of seconds at airports across the country to protect passengers and crews. This imaging technology is an integral part of TSA's effort to continually look for new technologies that help ensure travel remains safe and secure by staying ahead of evolving threats.

Currently, there are 40 millimeter wave imaging technology units in use at 19 airports. Six machines are used as primary screening at six airports and 34 machines are used for secondary, or random screening, as an alternative to a pat down at 13 airports.

TSA has tested both millimeter wave and backscatter imaging and announced that it plans to purchase an additional 150 backscatter units.

Use of advanced imaging technology is optional to all passengers.
