Abstract
A method for producing an image of a subject with a magnetic resonance imaging (MRI) system in which a signal contribution of a chemical species is depicted and a signal contribution of another chemical species is substantially separated is provided. For example, the provided method is applicable for water-fat separation. Spectral differences between at least two different chemical species are exploited to produce a weighting map that depicts the likelihood that one chemical species being depicted as another. A weighting map that characterizes the smoothness of a field map variation is also produced. These weighting maps are utilized to produce a correct field map estimate, such that a robust separation of the signal contributions of the at least two chemical species can be performed.
