  High spatio-angular resolution diffusion MRI (dMRI) has been shown to provide
accurate identification of complex neuronal fiber configurations, albeit, at
the cost of long acquisition times. We propose a method to recover intra-voxel
fiber configurations at high spatio-angular resolution relying on a 3D kq-space
under-sampling scheme to enable accelerated acquisitions. Simulations and real
data analysis suggest that accurate FOD mapping can be achieved from severe
kq-space under-sampling regimes potentially enabling high spatio-angular
resolution dMRI in the clinical setting.
