On the Use of Antipodal Optimal Dimensionality Sampling Scheme on the Sphere for Recovering Intra-Voxel Fibre Structure in Diffusion MRI

Bates, Alice P.;Khalid, Zubair;Kennedy, Rodney


In di usion magnetic resonance imaging (dMRI), the di usion signal can be reconstructed from measurements collected on single or multiple spheres in q-space using a spherical harmonic expansion. The number of measurements that can be acquired is severely limited and should be as small as possible. Previous sampling schemes have focused on using antipodal symmetry to reduce the number of samples and uniform sampling to achieve rotationally invariant reconstruction accuracy, but do not allow for...[Show more]
