Claim 2:
3. A system, comprising:
a processor in communication with a memory, the memory including instructions executable by the processor to:
access a k-space blade echo signal 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 set of odd sub-blade echoes, the set of odd sub-blade echoes including a first odd gradient echo sub-blade echo, a second odd gradient echo sub-blade echo, and an odd spin-echo sub-blade echo; and
a set of even sub-blade echoes, the set of even sub-blade echoes including a first even gradient echo sub-blade echo, a second even gradient echo sub-blade echo, and an even spin-echo sub-blade echo;

transform each sampled sub-blade echo of the k-space blade echo signal individually into image space;
correct a phase of each odd sub-blade echo to align with the odd spin-echo sub-blade echo in image space; and
correct a phase of each even sub-blade echo of the set of even sub-blades echo to align with the even spin-echo sub-blade echo in image
access calibration data for each sub-blade echo of the plurality of sub-blades of the k-space blade echo signal; and
transform the calibration data into image space to generate:
a set of odd sub-blade phase maps, the set of odd sub-blade phase data including a first odd gradient echo phase map, a second odd gradient echo phase map, and an odd spin-echo phase map; and
a set of even sub-blade phase maps, the set of even phase data including a first even gradient echo phase map, a second even gradient echo phase map, and an even spin-echo phase map.
