An accelerated sampling strategy is proposed that can effectively reduce both geometric distortion and scan time in the context of the high Angularly Resolved Diffusion Imaging(HARDI) diffusion-weighted imaging method. The approach combines sampling strategies inspired from accelerated dynamic imaging and from the rossing Fiber Angular Resolution of Intra-Voxel structure (CFRI) algorithm to resolve crossing fibers in a manner that is fast and fairly insensitive to susceptibility-induced field variations and geometric distortion.
