The agency says the algorithm update significantly reduces false alarms, enhances accuracy and reduces pat-downs. TSA also updated an algorithm to improve the performance of the nearly 1,000 advanced imaging technology units, technology that safely screens passengers for on-person metallic and non-metallic threats such as weapons and explosives without physical contact.
The technology reduces the need to touch or manually check bags and eliminates the need to take electronics and travel-size liquids, aerosols and gels (LAGs) out of carry-on bags. Throughout 2023, TSA added 267 computed tomography (CT) x-ray scanners, providing high-quality 3D images which can be rotated up to 360 degrees on three axes for a more thorough visual analysis of a carry-on bag’s contents.
