Smiths Detection 3D X-ray technology deployed in £1bn Heathrow upgrade

Smiths Detection, a global leader in threat detection and security screening technologies, today announces that its industry-leading 3D X-ray scanner, the HI-SCAN 6040 CTiX, has been deployed by London Heathrow Airport as part of a £1bn technology upgrade to become the largest airport to fully revolutionize the security screening process.

Smiths Detection’s technology will create a smoother, faster experience for travellers by allowing them to leave liquids and electronic devices in their hand luggage while passing through airport security. 

As part of the upgrade that Heathrow describes as a ‘major milestone’, Smiths Detection’s next generation computed tomography (CT) security screening technology has been rolled out across all passenger terminals, cutting queues and reducing stress for the millions of passengers who use the airport annually. 

What this means for passengers:
•    Liquids up to 2 litres remain in cabin bags
•    Electronic devices, including laptops and tablets, stay in bags
•    Fewer tray steps and a smoother, faster journey through security

Heathrow’s full rollout of advanced CT scanners from Smiths Detection marks a game-changing development for travellers while also enhancing passenger safety. With C3 compliance, the highest performance standard for explosives detection systems for cabin baggage, Heathrow now delivers greater security performance while significantly improving passenger flow and convenience.

Central to this transformation is the HI-SCAN 6040 CTiX scanner. Combining high-resolution volumetric imaging with powerful automatic threat recognition, the technology offers security teams clear, detailed views of bag contents and help reduce manual checks, enhancing throughput without compromising safety.

Andy Evripides, Head of Market UK and Ireland: “We are proud to support Heathrow’s journey toward modernised screening with the HI‑SCAN 6040 CTiX, building on a relationship that has spanned many years. Achieving C3 compliance is a shared milestone that demonstrates our joint focus on strong security, operational efficiency, and an improved passenger experience.”

Heathrow’s full deployment of CT technology is part of its broader investment in innovation and infrastructure, designed to meet stringent regulatory standards, improve operational performance and reinforce its status as a global aviation leader.

Heathrow originally selected Smiths Detection to supply its HI-SCAN 6040 CTiX in March 2021. Heathrow’s full announcement can be accessed here.
