Transportation Security Administration (TSA) at Antonio B Won Pat International Airport in Guam (GUM), an unincorporated territory of the US, has started using an advanced computed tomography (CT) scanner at its security checkpoint.

The scanner will help TSA officers to spot items inside carry-on luggage that can pose security threats.

During the screening process, an X-ray camera clicks several images while spinning around the conveyor belt to produce a 3D image of the insides of the bag being screened. At the same time, the CT scanner uses a sophisticated algorithm to examine and interpret them.

TSA officers can rotate the image on-screen for a thorough visual inspection to ascertain that no threats are contained in the bag, without opening it.

This will reduce the number of bags that need to be manually inspected to resolve a possible threat, eliminating potential touchpoints amid the ongoing pandemic.

TSA Pacific federal security director Jenel Cline said: “Travellers will see the new CT scanner in use in the security checkpoint at GUM. This unit provides improved security threat detection capabilities, allowing the TSA officer conducting X-ray screening to get a better view of the contents of the bag.

“We are pleased to have this new piece of screening equipment to increase the effectiveness and efficiency of our security operations.”

When the CT is in use, passengers can refrain from removing laptops and other electronic devices from their carry-on luggage.

However, travel-size liquids have to be removed before the X-ray screening.

TSA noted that this technology is similar to what is presently used in the medical field during a CT scan.

As of now, there are more than 280 CT units in place at 140 airports in the US.

In a separate development, P Plus Corporation, a provider of technology-driven mobility solutions, has announced that its Bags Aviation Division will provide Check ‘N Fly baggage check-in services to departing passengers at Tampa International Airport (TPA).

The new service will allow passengers to evade the airline ticket counter lines, maintain social distancing and proceed directly to TSA screening without waiting in line to check-in their luggage.
