New TSA Tech comes just in time for summer travel. Eight new advanced technology computed tomography (CT) scanners that provide 3-D imaging have been installed at the Transportation Security Administration (TSA) checkpoint at Buffalo Niagara International Airport (BUF). 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. Passengers using these machines at Buffalo will be permitted to leave their laptops and other electronic devices in their carry-on bags.
