LEXINGTON, Ky. — A new state-of-the-art computed tomography checkpoint scanner (CT) that provides 3-D imaging has been installed and is in use at the Transportation Security Administration (TSA) checkpoint at Blue Grass Airport (LEX).
The new technology provides critical explosives detection capabilities at the checkpoint and improves the capability for TSA officers to determine whether an item inside a carry-on bag is a possible threat.
The system applies sophisticated algorithms for the detection of explosives by creating a 3-D image that can be viewed and rotated on three axes for thorough visual image analysis by a TSA officer. If a bag requires further screening, TSA officers will inspect it to ensure that a threat item is not contained inside.
“The new unit is an enhancement in our security capability, but it also reduces the need for pulling aside a bag to be opened, thus reducing a touchpoint during the pandemic.,” said Ray Williams, TSA’s Federal Security Director for Kentucky.
This equipment is similar to what is used to scan checked baggage for explosive devices, and has been “sized” to fit at checkpoints to create such a clear image of a bag’s contents that the system can automatically detect explosives, including liquids, by shooting hundreds of images with an X-ray camera spinning around the conveyor belt to provide TSA officers with the three-dimensional views of the contents of a carry-on bag.
Checkpoint CT technology should result in fewer bag checks. Passengers using this machine at LEX will be permitted to leave laptops and other electronic devices in their carry-on bags.
