Equivariant spatio-hemispherical networks for diffusion MRI deconvolution
Exploiting the antipodal symmetry of diffusion MRI signals, the authors build an E(3)xSO(3)-equivariant deconvolution network on hemispheres, cutting computation 2 to 5 times while matching or improving fiber orientation recovery.
