Effective
dipole fitting removes susceptibility induced global background field. It
assumes that each independent voxel outside a given region of interest (ROI)
are responsible for the background field inside that ROI. It removes the
field generated by these sources, while preserving the field arising from
local susceptibility variations inside the ROI.
