Single-shot sequences utilizing spatiotemporal encoding
(SPEN) provide robust alternatives to single-shot EPI
with similar acquisition durations and comparable
resolution, provided that specialized super-resolved
reconstruction algorithms are used in the image
retrieval. Acquisition imperfections known to cause
ghosting artifacts in EPI, can also give rise to
artifacts in processed Hybrid-SPEN images. We
demonstrate that these experiments, unlike EPI, do not
require a reference scan to correct for these
imperfections. A self-referencing algorithm based on the
fact that under-sampling along the SPEN direction does
not generate aliasing, but rather lower resolution
images, is developed. The referenceless algorithm and
sample results are presented.
