1Neuroimaging Research, Barrow Neurological Institute, Phoenix, AZ, United States We introduce a new closed-form multipoint water-fat reconstruction algorithm with flexible echo time increments. Two sets of possible solutions of water, fat and field map are computed from images acquired at N (N>2) echo times. Under the assumption of the local smoothness of the field map, the solutions for water, fat are resolved by thresholding, region-growing and bilinear fitting of the field map. An implementation with multi-coil spiral imaging has demonstrated the feasibility of this method.
