摘要
In a nuclear magnetic resonance tomography apparatus and a method for the operation thereof, on the basis of the 3-point Dixon method, spin collectives having different chemical shifts are separated by means of information maximization despite great field inhomogeneities. The unwrapping of the phases is implemented over interconnected pixel regions (phase unwrapping) proceeds initially only in regions with high signal amplitude and the regions of lower amplitudes are only successively acquired by increments. These are then allocated to the respectively correct spin type, such as fat or water.
