Fibre
Orientation Distributions (FODs) computed by Constrained Spherical
Deconvolution can resolve multiple fibres within a single voxel. We have
developed a symmetric diffeomorphic registration method to exploit crossing
fibre information provided by FODs to spatially normalise high angular
resolution diffusion weighted imaging data. We demonstrate the utility of the
proposed method by generating a group average FOD template.
