Heathrow Airport's new security scanners use advanced Computed Tomography (CT) technology to create detailed three-dimensional images of cabin baggage, improving both security and passenger convenience.
A New Standard for Airport Security
Heathrow Airport has introduced advanced Computed Tomography (CT) security scanners across all passenger terminals, representing one of the most significant improvements to airport screening in recent years. The new technology has been implemented to strengthen aviation security while making the screening process quicker, simpler, and more convenient for millions of passengers travelling through the UK's busiest airport.
Unlike traditional X-ray systems, the latest scanners produce detailed three-dimensional images of cabin baggage, allowing security officers to inspect items with greater accuracy. This enhanced capability reduces unnecessary manual bag checks and helps improve the flow of passengers through security checkpoints.
Whether you are travelling for business, leisure, or an international connection, understanding how Heathrow Airport's new security scanners work can help you prepare for a smoother journey.
Why Heathrow Upgraded Its Security Scanners
As passenger numbers continue to grow, Heathrow remains committed to investing in technology that improves both security and customer experience. The rollout of CT scanners supports the airport's long-term strategy of delivering safer, more efficient, and more reliable airport operations.
The new screening technology has been introduced to.
- Strengthen aviation security.
- Improve baggage screening accuracy.
- Reduce manual luggage inspections.
- Speed up passenger processing.
- Minimise congestion at security checkpoints.
- Enhance the overall airport experience.
These improvements help Heathrow deliver a more modern and efficient journey while maintaining strict international security standards.
How the New CT Security Scanners Work
Computed Tomography technology creates high-resolution three-dimensional images of cabin baggage. Unlike conventional X-ray machines, security officers can rotate and inspect images from multiple angles without opening most bags.
This allows security teams to identify potential risks more effectively while reducing unnecessary secondary inspections.
For many passengers travelling through Heathrow, the new screening process means.
- Laptops and tablets can generally remain inside cabin baggage.
- Permitted liquids can usually stay inside hand luggage.
- Less preparation is required before entering security.
- Fewer plastic liquid bags are needed.
- Reduced waiting during peak travel periods.
- Faster movement through security lanes.
Passengers should always follow the instructions provided by Heathrow security staff, as additional screening may still be required when necessary.
