Here we present a set of metrics and experiments that
evaluate the performance of several single- and
multi-shell high angular resolution diffusion imaging
(HARDI) acquisition schemes. In particular, we assess
the angular resolution, the peak accuracy, the peak
precision as well as the distribution function accuracy
and distribution function precision at several different
fiber configurations. We show that low b-value
acquisitions in a multi-shell configuration can reach
similar performances as high b-value acquisitions on a
single shell.
