Researchers recently unveiled a prototype magnetoencephalography (MEG) brain scanner that is worn like a helmet and allows movement.
All MEG systems noninvasively measure magnetic fields outside the skull created by brain activity. Current MEG scanners use superconducting sensors housed in cooling chambers. The one-size-fits-all machines are large and heavy and require patients to stay still while their head is immobilized inside them, limiting their clinical usefulness.
