Noise and artifact suppression in SQUID and wearable OPM-MEG: A systematic review of background, physiological, and Technical interference

NeuroImage
Magnetoencephalography (MEG) is a non-invasive imaging technique that captures neural activity with high spatio-temporal resolution. In recent years, novel wearable devices based on Optically Pumped Magnetometer (OPM) have emerged as a new driving force ...

Spatial Resolution of Low-Density OPM-MEG: A Comparative Analysis With High-Density EEG

IEEE Transactions on Instrumentation and Measurement
Electroencephalography (EEG) and magnetoencephalography (MEG) are noninvasive neuroimaging techniques used to detect and localize brain activity. Unlike cumbersome MEG systems that employ superconducting quantum interference devices (SQUIDs), EEG and the

Source Extent Estimation in OPM-MEG: A Two-Stage Champagne Approach

IEEE Transactions on Medical Imaging
The accurate estimation of source extent using magnetoencephalography (MEG) is important for the study of preoperative functional localization in epilepsy. Conventional source imaging techniques tend to produce diffuse or focused source estimates that fail to capture the source extent accurately.
