Brain Connectivity Using Geodesics in HARDI

We develop an algorithm for brain connectivity assessment using geodesics in HARDI (high angular resolution diusion imaging). We propose to recast the problem of nding bers bundles and connectivity maps to the calculation of shortest paths on a Riemannian manifold dened from ber ODFs computed from HARDI measurements. Several experiments on real data show that our method is able to segment bers bundles that are not easily recovered by other existing methods.
