MEG is a non-invasive form of imaging which measures the tiny magnetic fields produced by electrical activity in the brain. It can be used to analyse brain function with millisecond and millimetre precision, allowing clinicians to identify the exact location of the source of epileptic seizures, for instance.
Until now, MEG scanning - which is not as mature as other forms of imaging, such as MRI - has required the patient to stay completely still during the scan, sometimes requiring sedation. Traditional MEG scanners are also optimised for adults and are of limited use in children due to their size.
The development of the first wearable MEG helmet will make the process far easier for children, especially those with complex needs, by allowing them to move freely during the scan. The helmet can fit a child of any age and provides higher sensitivity and spatial precision compared to the current scanner.
