Quicker baggage scans for safer flights

News

University of Manchester mathematicians are combining 2D X-rays from airport hold baggage scans into 3D images to better detect dangerous content and help reduce bottlenecks.

Most airport X-ray machines currently in use only provide a 2D view of a bag’s contents. The new system, now at the working prototype stage, not only generates better images but also does so very quickly. This offers potential reductions in baggage processing times, which could help avoid flight delays.

The system is being developed by CXR, a research-led organisation set up by airport security specialist Rapiscan Systems. The Manchester mathematicians, funded by CXR and the EPSRC, have been overcoming the mathematical challenges involved in developing the specialised computer hardware and software that underpin the system’s capabilities.

The 3 year project, ‘X-ray CT reconstruction algorithms for airport security and process tomography’, is receiving EPSRC funding of nearly £504,000.
