A Nonparametric Riemannian Framework for Processing High Angular Resolution Diffusion Images (HARDI)
15 years 5 months ago
High angular resolution diffusion imaging has become an
important magnetic resonance technique for in vivo imaging.
Most current research in this field focuses on developing
met...
