High-end brain imaging for precision personalized medicine with OPM-MEG

We believe that our ergonomic, reliable, and room temperature technology will pave the way for a new era of Magnetoencephalographs (MEGs), improve care for patients suffering from brain disorders, starting with diagnosis and rehabilitation after concussion and pre-surgery for epilepsy.

Magnetoencephalography

MEG records the magnetic signature of the electrical currents generated by the neuronal activity.

MEG is the only neuroimaging device that provides millisecond-scale information on brain activity with an anatomical accuracy of a few tens of mm³. It can also provide functional information on brain networks in time-frequency space.  

MEG is not invasive, safe, using neither radiation nor injection.

Technology

Quantum sensors

MAG4Health takes advantage of a quantum technology that works at room temperature to simplify the installation and the use of the MEG. The technology, developed at CEA, is the helium optically-pumped magnetometer.
