In this study, we proposed a motion-compensated Iterative Self-consistent Parallel Imaging (SPIRiT) acceleration scheme with analytical Q-Ball imaging (QBI) based reconstruction4 to obtain orientation distribution function (ODF) with high spatial and angular resolution. This metric demonstrates improved quality with reduced noise and motion artifacts compensated with the method.
