Determining and correcting for phase jumps

摘要

A continuous phase magnetic field map is provided by dividing the field map of elements into regions; determining discontinuities in the regions and adding a constant modulo 2 pi to the phase values of each element of the region which results in a minimum difference between adjacent elements of the region. Then similarly joining the continuous regions to form continuous sections and the continuous sections to form continuous zones until substantially continuous phase magnetic field maps are obtained.
