Transportation Security Administration (TSA) is planning to test a new computed tomography checkpoint scanner (CT) at its checkpoint located at Baltimore Washington International-Thurgood Marshall Airport in the US.

The advanced technology, which offers 3D imaging, provides critical explosives detection capabilities at the TSA checkpoint.

It creates a 3D image that can be viewed and rotated on three axes for thorough visual image analysis by a TSA officer and applies sophisticated algorithms to detect explosives.

The officers will inspect a bag to ensure no threat item is contained inside, or if it requires further screening. The CT test will be carried out in Concourse C at the airport.

“Use of CT technology substantially improves TSA’s threat detection capability at the checkpoint.”

TSA administrator David Pekoske said: “TSA is committed to getting the best technology to enhance security and improve the screening experience. Use of CT technology substantially improves TSA’s threat detection capability at the checkpoint.”

The system, which is similar to the one used for scanning checked baggage for explosive devices, has been ‘sized’ in such a way that it fits at checkpoints to create a clear image of the contents of a bag.

This would enable the system to automatically detect explosives, including liquids, by capturing several images with an X-ray camera spinning around the conveyor belt. This then provides three-dimensional views of the contents of a carry-on bag to TSA officers.

Passengers using Checkpoint CT technology at BWI Airport will be permitted to leave laptops and other electronic devices in their carry-on bags.

TSA plans to install up to 40 units in place at airports across the country by the end of the year, along with 16 units at federal testing facilities.

By the end of the fiscal year 2019, more than 145 will be in airports.
