A Joint Estimation Method for Two-Point Water/fat Imaging with Regularized Field Map

Diego Hernando¹, Peter Kellman², Zhi-Pei Liang¹

Two-point methods for water/fat imaging are attractive because of their moderate acquisition time. In this work, we adapt a previously proposed joint estimation approach for two-point acquisitions and demonstrate its performance using simulations, phantom results and in vivo data. The proposed method, based on a regularized formulation and a graph cut solution, results in good noise properties and the ability to handle large B0 field inhomogeneities.
