Source localization using virtual magnetoencephalography helmets: A simulation study toward a prior-based tailored scheme

Source localization using virtual magnetoencephalography helmets: A simulation study toward a prior-based tailored scheme

Magnetoencephalography (MEG) source estimation of brain electromagnetic fields is an ill-posed problem. A virtual MEG helmet (VMH), can be constructed by recording in different head positions and then transforming the multiple head-MEG coordinates into one head frame (i.e., as though the MEG helmet...
