MAVIS was the first 3D scanner developed since 1988 in the Medical Imaging Laboratories at the University of Glamorgan. The name MAVIS means Measurement of Area and Volume Instrument System and was coined to describe its use in measuring the dimensions of wounds.
This instrument was based on the structured light technique and weighed more than 100kg. It has been superseeded by MAVIS-II and is now obsolete.
