We introduce a robust algorithm to resolve the
ambiguities in fat-water decomposition by utilizing the
smoothness of the field-map in three spatial dimensions.
Many current methods are still sensitive to local minima
effects. We had recently introduced a novel graph cut
algorithm termed as GlObally Optimal Surface Estimation
(GOOSE) that is guaranteed to provide the global
minimum, which was observed to considerably improve the
performance on challenging datasets. However, GOOSE was
restricted to two dimensional and hence not capable of
exploiting the field smoothness between slices. This
work is to extend GOOSE to 3-D therefore to further
improve the robustness.
