A computed tomography checkpoint scanner is to be installed at the TSA checkpoint at Elmira Corning Regional Airport.

Elmira Corning Regional Airport in Chemung County, New York, will have its security screening boosted later this month with the installation of a computed tomography (CT) checkpoint scanner.

The new system applies algorithms for the detection of explosives by creating a 3-D image that can be viewed and rotated on three axes for visual image analysis by a TSA officer. If a bag requires further screening, TSA officers will inspect it to ensure that it does not contain a ‘threat item’. 

The new unit will be installed in the week of January 31, with installation expected to take several days.

“Use of CT technology substantially improves threat detection capability at the checkpoint,” said Bart R Johnson, TSA’s federal security director. “TSA’s current screening technology for carry-on bags uses 2-D images. The CT technology applies sophisticated algorithms for the detection of explosives, including liquid explosives and other threat items.”

This new technology creates 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, according to the TSA. Passengers using this machine will be allowed to leave laptops and other electronic devices in their carry-on bags.
