Towards a 384-channel magnetoencephalography system based on optically pumped magnetometers
Holly Schofield, Ryan M. Hill, Lukas Rier +13
Magnetoencephalography using optically pumped magnetometers (OPM-MEG) is gaining significant traction as a neuroimaging tool, with the potential for improved performance and practi…
Determining sensor geometry and gain in a wearable MEG system
Ryan M. Hill, Gonzalo Reina Rivero, Ashley J. Tyler +12
Optically pumped magnetometers (OPMs) are compact and lightweight sensors that can measure magnetic fields generated by current flow in neuronal assemblies in the brain. Such senso…
Designing optimal loop, saddle, and ellipse-based magnetic coils by spherical harmonic mapping
Peter James Hobson, Noah Louis Hardwicke, Alister Davis +8
Adaptable, low-cost, coils designed by carefully selecting the arrangements and geometries of simple primitive units are used to generate magnetic fields for diverse applications.…
Benchtop magnetic shielding for benchmarking atomic magnetometers
