MULTIPOINT DIXON TECHNIQUE

摘要

The predetermined spectral model of the multipoint Dixon technique comprises: at least two spectral components with respective associated relaxation rates; A first phase due to magnetic field non-uniformity; And second phase due to eddy current effect. MR data 25 is by a bipolar multi-echo MR measurement sequence 5 for multiple image points and for each image point the multi-point MR measurement sequence 5 comprises at least three echo times 21, 22, 23 alternately use positive and negative readout gradient magnetic fields 16-1, 16-2, 16-3 for reading MR signals of MR data. At least two spectral components may be determined based on the MR data 25.;
