The Transportation Security Administration (TSA) at the Antonio B. Won Pat International Airport in Guam has installed a new computed tomography (CT) scanner in the security checkpoint. The scanner utilizes state-of-the art technology and improves the ability of TSA officers to detect items inside carry-on luggage that are potential security threats.

The CT scanner applies a sophisticated algorithm during the screening process while an X-ray camera shoots hundreds of images while spinning around the conveyor belt, generating a 3-D image of the contents of the items being screened.

A TSA officer is able to manipulate the X-ray image on-screen for a thorough visual analysis, clearing the contents of the bag without having to open it. Reducing the number of bag checks is beneficial since it eliminates potential touchpoints amid the ongoing coronavirus pandemic.

“Travelers 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,” said TSA Federal Security Director for the Pacific Jenel Cline. “We are pleased to have this new piece of screening equipment to increase the effectiveness and efficiency of our security operations.”

Travelers whose carry-on luggage is screened by a CT scanner can leave laptops and other electronic devices in their carry-on bags. Travel-size liquids should be removed prior to X-ray screening.

This technology is similar to what is currently used in the medical field during a CT scan. TSA has used CT technology to screen checked baggage for several years and there are more than 280 CT units in place at 140 airports nationwide. TSA began using the CT scanner at GUM this week.
