Computed tomography (CT) has long been used by airports to screen hold baggage. CT technology offers 3D imaging and automatic threat detection, enabling operators to effectively identify prohibited items. CT scanners are the only systems to achieve ECAC's type D and D+ approvals, which means these systems allow passengers to leave laptops, tablet devices and LAGs (liquids, aerosols and gels) in carry-on bags. CT systems are under trial at several key airports in Europe as a method of optimising the checkpoint.
One company that is driving innovation at the checkpoint is Analogic Corporation. Analogic has developed platform checkpoint technology to optimise the airport checkpoint and meet the needs of tomorrow's airports. The COBRA checkpoint CT system is ECAC type D and D+ (standard 2) -approved, the only system in the world with this level of threat detection. The COBRA enables higher throughput, enhanced detection, reduced life cycle costs and improved passenger experience compared with current AT2 systems. There is significant process improvement because passengers can 'throw and go,' which means carry-on bags can be placed on the conveyor belt without divesting laptops, tablets, liquids or duty-free purchases.
Analogic understands that higher throughput means airports can do more with fewer scanners. Although CT scanners are perceived as more expensive, overall cost of ownership can save airports millions and is a significant contributor to the growing importance of airports as hubs for commerce.
