Claim Text:
1. A method of imaging at least two chemical species using magnetic resonance imaging with signal separation for the two chemical species, the method comprising: acquiring first and second echo data at different echo times resulting in a first and second acquired complex dataset; modelling the first and second acquired dataset, said modelling comprising a spectral signal model of at least one of the chemical species; identifying in the first and second acquired dataset the voxels for which the modelling yields a single, unambiguous mathematical solution for the signal separation; resolving the ambiguity for the voxels for which the modelling yields more than one mathematical solution, if any such voxels remain; and predetermining the different echo times, wherein said predetermination comprises: wherein for the non identified voxels find all mathematical solutions for the signal separation are calculated by means of the modelling and then one mathematical solution is selected based on the identified voxels located in the immediate neighborhood to said non identified voxels.
