Key to the success of phase-sensitive water-fat separation lies in robust estimation of field inhomogeneities. This work describes a novel field map estimation technique that systematically incorporates field map smoothness and a priori likelihood of field map values via belief propagation algorithm, which perform joint estimation of field inhomogeneities across 2D image grid.
