Researcher creates optical magnetometer prototype that detects errors in MRI scans

Hvidovre Hospital has the world's first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical sensors--and hopefully pave the way for MRI scans that are better, cheaper and faster.
