Currently, passengers have to remove items such as electronic items and liquid from hand luggage and put them on trays for security checks. Once implemented, the 3D CTX machines will reduce the time taken for security checks at airports. Passengers wont need to take out electronic devices like laptops or chargers and liquids and put them on trays at security checkpoints.
Airports will also have to reconfigure the layouts at airports as CTX machines are larger than the 2D X-ray scanners in use currently. Besides passenger convenience, CTX machines will also improve detection of prohibited items.
London City Airport in April this year, according to a BBC report, allowed electronics to be kept in hand luggage at security after installation of the CTX machines. The UK government has set a June 2024 deadline for most UK airports to install the machines.
“CTX will not only improve passenger experience at airports by speeding up PESC process, but also improve detection of prohibited items and make security more robust. This will enhance the capability of detecting non-metallic threat objects like liquid, gel or plastic contraband,” TOI had reported citing sources .
How the 3D CTX machines work
The CTX detection systems provide high-resolution 3D images, enhancing the analysis of details and specific structures of suspected threats. It helps in efficient security decisions on all checked bags and cargo packages. These machines use 3D imagery, algorithmic calculations and dual-energy organic/inorganic image capabilities to identify threats, according to Smiths Detection website.
