TSA scanners could let US travellers keep liquids, laptops in carry-on

The TSA said July 30 it plans to roll out computed tomography scanners (CT) at a host of airports in cities across the US. The agency predicted that using CT scanners at checkpoints would lead to fewer bag checks, and that passengers may also be able to keep laptops and liquids in their carry-on luggage in the future. The 3D technology, which has long been used for medical imaging in hospitals, is intended to enhance detection capabilities of critical explosives and other threat items. The CT system uses advanced algorithms to detect explosives and constructs a 3D image that can be rotated 360 degrees and viewed on 3 axes by TSA officers. The scanners provide the agency with a clearer view than traditional X-ray machines. <br/>
