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.
