Simulations improve MEG spatial resolution – Physics World

Improved beamforming and 3D printed headcasts increase the spatial resolution of magnetoencephalography

MEG reveals separate spatial locations of the beta rebound for the index finger (red) and little finger (blue) in a single participant. (Courtesy: E Barratt et al NeuroImage 10.1016/j.neuroimage.2018.06.041/CC BY 4.0) Researchers at the University of Nottingham have demonstrated an optimized method to analyse magnetoencephalography (MEG) data that can improve spatial resolution to the order of 3-5 mm. They achieved this with the aid of an optimized algorithm and custom 3D-printed foam headcasts that restricted participant head movement to about 1 mm. First shown in simulation, then validated i
