Brain surgery requires accurate diagnosis and planning. MagnetoEncephaloGrapgy (MEG) is extremely accurate but is not widely used because it is not affordable. As a partner in the EU-funded gateoneproject, CEA LETI’s research team has developed a new sensor that will cut the cost of MEG by a factor of 5. In partnership with BLUMORPHO, the Scientific coordinator of the Gateone project, a whole value chain is gathered on a roadmap for product development and commercialization that sees this technology delivering a breakthrough in the Medical field. Furthermore applications of this sensor for geological and airborne applications are also on the commercialization roadmap.

What is the innovation
The Gateone project invested into a compact Ultra-Low Noise Optically Pumped Magnetometer (ULNOPM). The 20cm3 sensor, which is protected by 19 patents, is a 10x improvement in compactness and delivers a 4 times reduction on noise. In addition, it is maintenance free and does not require cooling or heating compared to the competition. These features will enable a cost breakthrough in Magnetoencephalography (MEG) which is a unique tool for brain surgical planning but remains rarely used because of the huge infrastructure investment and cost of ownership.
