The Transportation Security Administration (TSA) recently announced their plan to test new 3-D technology at security checkpoints to detect explosives and other threats in carry-on baggage. This new scanning equipment, which uses computed tomography (CT) technology, will hopefully result in fewer bag checks and may even make it possible in the future for passengers to leave their laptops and liquids in their carry-ons when going through security. We can only hope.
The screening technology TSA currently uses only generates 2-D images. The 3-D CT technology allows the images to be rotated 360 degrees for more thorough analysis, but TSA officers will still inspect any bags that require further screening.
By the end of 2018, TSA plans to have 40 units in 15 airports around the U.S. and 145 units by the end of fiscal year 2019. If you or your clients traveling through the following airports, you may experience the new scanners:
Travelers through PHX, BOS and JFK may have already put their carry-on through a new scanner, since testing began at PHX and BOS in June 2017 and JFK in July 2018.
