Advanced Imaging Technology (AIT)

Traveler's Guide

TSA began testing state-of-the-art Advanced Imaging Technology in 2007 and began deploying units to airports in 2008. This technology can detect a wide range of threats to transportation security in a matter of seconds to protect passengers and crews. 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.

TSA uses two types of imaging technology, millimeter wave and backscatter. Approximately 800 Advanced Imaging Technology units are deployed at more than 200 airports nationwide, aiding in the detection of prohibited, illegal or dangerous items.

Advanced Imaging Technology screening is safe for all passengers and the technology meets national health and safety standards. 

TSA implemented strict measures to protect passenger privacy which is ensured through the anonymity of the image. Additionally, advanced imaging technology screening is optional for all passengers.

TSA Installs New AIT Software

TSA installed new software on all millimeter wave Advanced Imaging Technology (AIT) machines designed to enhance privacy by eliminating passenger specific images.

Passenger Acceptance

Since imaging technology has been deployed at airports, more than 99 percent of passengers choose to be screened by this technology over alternative screening procedures. According to a new CBS poll, 4 out of 5 Americans support the use of advanced imaging technology at airports nationwide. Click here to see more independent polling on AIT acceptance. (cbsnews.com)

Additionally, passengers with joint replacements or other medical devices that would regularly alarm a metal detector often prefer this technology because it is quicker and less invasive than a pat down.
