AB Won Pat International Airport in Guam, US, is to get two advanced imaging technology machines from the US Transportation Security Administration (TSA) to screen passengers boarding aircraft.
The new machines will streamline the checkpoint screening process and improve capacity, according to guampdn.com.
The machines will be deployed with new automated target recognition software, and are designed to improve privacy by eliminating passenger-specific images.
Advanced imaging technology enhances security by safely screening passengers for metallic and non-metallic threats such as weapons, explosives and other objects that are concealed under layers of clothing.
"The airport will deploy two scanners and three metal detectors, and passengers can expect to be screened soon after the scanners arrive," said Brian Cahill, the US Department of Homeland Security’s TSA federal security director. "The scanners are much more powerful than metal detectors, and passengers will have to remove more than just metal objects from their person."
The scanners produce a generic outline or an image of a person; there are about 540 imaging technology units at more than 100 US airports.
The scanners use either millimetre wave technology, which reflects electromagnetic waves off the body, or backscatter technology, which projects low-level X-ray beams over the body.
This technology can detect threats to transportation security within seconds.
Previously, the airport spent $34m on improving its capacity; projects included extending the runway, installing navigational aids and completing the construction of a parallel taxiway.
