In this work, we present a two-point Dixon method with
flexible echo times where the smoothness of the
inhomogeneity field is imposed as an non-convex energy
minimization problem, solved by Quadratic Pseudo-Boolean
Optimization (QPBO). Robust water/fat separation is
achieved in in contrast enhanced dynamic liver imaging
at 1.5T.
