New wearable, high-precision brain scanner allows for patients to move around

IMG_7590

A radical new wearable magneto encephalography (MEG) brain scanner under development at the University of Nottingham allows a patient to move around, instead of having to sit or lie still inside a massive scanner.

Currently, MEG scanners* weigh around 500 kilograms (about 1100 pounds) because they require bulky superconducting sensors refrigerated in a liquid helium dewar at -269°C. Patients must keep still — even a 5mm movement can ruin images of brain activity. That immobility severely limits the range of brain activities and experiences and makes the scanner unsuitable for children and many patients.
