Dixon techniques offer robust water/fat separation in the presence of static field inhomogeneity. Two-point Dixon imaging with flexible echo times is desirable because of its high scan efficiency and flexibility. A major challenge in two-point Dixon imaging is how to estimate the phase error resulting from field inhomogeneity. In this work, we formulate a binary quadratic optimization and propose a fast projected power method to resolve the phase ambiguity in two-point Dixon imaging.
