Several techniques have been used to explore the
information contained in the diffusion propagator. A
standard methodology to evaluate such techniques (and
the influence of factors such as acceleration methods)
is to compare the reconstructed orientation distribution
functions against a predefined "gold standard".
Nonetheless additional measures may retrieve more
information from the diffusion propagator. In this work
we present preliminary results that may allow a more
robust analysis and comparison of diffusion data and
acceleration methods. Specific indices were extracted
and appear to be helpful in the characterization of the
diffusion propagator and in the comparison of different
reconstruction methods
