Scanning someone’s brain using Magnetoencephalography, or MEG, can be tricky. The scanners are currently bulky, one-size-fits-all machines that require you to sit perfectly still inside them. This makes it difficult to scan small children, or patients that are likely to move around a lot.
Now, researchers at the University of Nottingham have developed a prototype MEG scanner that a patient can wear on their head. It could theoretically be customised to fit any shape of head and, crucially, the patient can move around and perform different actions while having their brain scanned.
