To realize human magnetoencephalography (MEG) measurements, we evaluated an NV magnetometer integrated with flux concentrators (FCs). Dry-phantom measurements demonstrated a magnetic field enhancement factor of approximately 60, and the sensitivity was estimated to be approximately 7 pT/Hz^1/2. Assuming a brain magnetic field of 200 fT, approximately 5,000 signal averages are required for MEG measurements.
