Magnetoencephalography (MEG) is a non-invasive imaging technique for investigating human brain function, uniquely capable of measuring brain activity with good spatial and temporal resolution. MEG operates by detecting magnetic fields naturally produced by the brain, with no applied fields or injections. Epilepsy diagnosis is the most advanced clinical application for MEG but other use cases for MEG are also growing. Optically-pumped magnetometers (OPMs) are a cryogen-free quantum sensor technology with extraordinary magnetic sensitivity.
OPM provides a superior balance of sensitivity, size and proximity to the cortex, but have not yet been implemented in technologies that are simultaneously manufacturable at scale, high-performing, and cost-effective. OPMMEG will develop an OPM array that meets these requirements for wide-spread use of OPMs in MEG.
