Multichannel system based on a high sensitivity superconductive sensor for magnetoencephalography

Sensors (Basel). 2014 Jul 8;14(7):12114-26. doi: 10.3390/s140712114.

Abstract

We developed a multichannel system based on superconducting quantum interference devices (SQUIDs) for magnetoencephalography measurements. Our system consists of 163 fully-integrated SQUID magnetometers, 154 channels and 9 references, and all of the operations are performed inside a magnetically-shielded room. The system exhibits a magnetic field noise spectral density of approximatively 5 fT/Hz(1=2). The presented magnetoencephalography is the first system working in a clinical environment in Italy.
