High quality background field removal is a critical yet
challenging step in quantitative susceptibility mapping
(QSM), as it involves phase unwrapping, skull stripping,
and knowledge of the boundary conditions. In this work,
we provide a theoretical analysis of the background
field removal and propose to bypass all the steps using
a differential equation approach.
