Claim 23:
24. The method of claim 1, the plurality of phase maps including an odd spin-echo phase map and an even spin-echo phase map, the method further comprising:
generating, by the processor and using the odd spin-echo phase map and the even spin-echo phase map, a spin-echo phase difference map that corresponds to a phase difference between an odd spin-echo sub-blade echo and an even spin-echo sub-blade echo of the plurality of sub-blade echoes, the odd spin-echo sub-blade echo being oriented orthogonal to the even spin-echo sub-blade echo; and
removing, by the processor, the spin-echo phase difference map from each sub-blade echo of the plurality of sub-blade echoes in image space;
the odd spin-echo phase map corresponding to calibration data for an odd spin-echo sub-blade echo of the plurality of sub-blade echoes of the k-space blade echo signal; and
the even spin-echo phase map corresponding to calibration data for an even spin-echo sub-blade echo of the plurality of sub-blade echoes of the k-space blade echo signal.
