The US Transportation Security Administration (Tsa) at Syracuse Hancock International in New York has started using an advanced computed tomography (CT) checkpoint scanner at its security checkpoint.

Through its 3D imaging, the new scanner has enhanced capabilities to detect explosives.

TSA Upstate New York federal security director Bart R Johnson said: “The new checkpoint technology provides critical explosives detection capabilities and improves the capability for our TSA officers to determine whether an item inside a carry-on bag is a possible threat.”

To detect explosives, the system uses sophisticated algorithms and creates a 3D image that can be viewed and rotated on three axes for improved visual analysis by a TSA officer.

In case luggage needs additional screening, TSA officers will examine it to ensure that the bag is not containing any hazardous item.

With the help of 3D imagery, TSA officers will be able to manipulate the image on the screen to get a better view of contents within a bag, thereby eliminating the need for the TSA officers to carry out manual inspections.

Johnson said: “Not only does this state-of-the-art technology represent an improved security threat detection capability at the checkpoint, but it also reduces the need for pulling aside a bag to be opened, thus reducing a touchpoint during the pandemic.”

The agency said that the equipment is similar to what is used for scanning checked luggage for explosive devices.

The scanner has been built to fit at the checkpoints of the airport.

Travellers using this machine at the airport will be allowed to leave laptops and other electronic devices in their carry-on bags.

The agency said that the new equipment will result in fewer bag checks.

TSA recently deployed credential authentication technology (CAT) and computed tomography (CT) scanners at El Paso International Airport (ELP).

CAT authenticates the validity of travellers’ identifications (IDs), along with their flight information, in near real-time.

At the travel document checking station, travellers are required to hand over their ID to the security officer, who will confirm the authenticity of the document by inserting it in the CAT unit.
