We introduce a motion-resolved solution to clinical brain MRI for quantitative multiparametric mapping using Multitasking, which is generalizable to translation, rotation, discrete and periodic motion without explicit need for motion correction or compensation.

reconstruction schematics for motion-resolved brain MRI.
Figure 5. In vivo demonstration of no
motion (top), discrete motion experiment (bottom left) and periodic motion
experiment (bottom right) with no motion
handling, motion-removal, and motion-resolved, along with example images of
identified motion states. The proposed motion-resolved solution provided the
best image quality
with sharper tissue structures and less blurring/ghosting artifacts.
