Claim 1:
2. A method, comprising:
accessing, by a processor in communication with a memory, a k-space blade echo signal sampled by a magnetic resonance device in communication with the processor, the k-space blade echo signal including a plurality of sub-blade echoes, the plurality of sub-blade echoes including a plurality of odd sub-blade echoes including an odd spin-echo sub-blade echo and a plurality of even sub-blade echoes including an even spin-echo sub-blade echo;
transforming, by the processor, each sub-blade echo of the plurality of sub-blade echoes individually into image space;
generating, by the processor, a spin-echo phase difference map corresponding to a phase difference between the odd spin-echo sub-blade echo and the even spin-echo sub-blade echo in image space; and
correcting, by the processor, a phase of a sub-blade echo of the plurality of sub-blade echoes to align with the even spin-echo sub-blade echo or the odd spin-echo sub-blade echo in image space by:
removing the spin-echo phase difference map from each odd sub-blade echo of the plurality of sub-blade echoes in image space to align with the even spin-echo sub-blade echo; or
removing the spin-echo phase difference map from each even sub-blade echo of the plurality of sub-blade echoes in image space to align with the odd spin-echo sub-blade echo.
