Choice of Magnetometers and Gradiometers after Signal Space Separation

open access: yesSensors, 2017
Background: Modern Elekta Neuromag MEG devices include 102 sensor triplets containing one magnetometer and two planar gradiometers. The first processing step is often a signal space separation (SSS), which provides a powerful noise reduction.
