New sensor 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.  . . . .   Hans Stærkind’s prototype works using a device for sending and receiving laser light that looks like a 1990’s stereo system. It sends laser light through fiber optic cables — i.e., without any metal — and into four sensors located in the scanner.  Within the sensors, the light passes through a small glass container containing a caesium gas, which absorbs the light at the right light frequencies.”     MORE
