Cardiff University uses 3D scans to help facial surgery
Patients who need facial surgery and those recovering from strokes could benefit from world-leading research of analysing facial movements in 3D.
Scientists at Cardiff University are using cutting-edge face scanners developed by American firm 3dMD.
The technology can also record the facial movements of two individuals simultaneously while they talk.
It allows more detailed analysis than by either direct observation or video recordings.
Consultant orthodontist Dr Hashmat Popat explains to BBC Wales health correspondent Owain Clarke why it is so useful for doctors.
He is followed by Prof David Marshall, from the university's school of computer science and informatics, who talks about the challenges for the software developers.
