PRISM: Differentiable Analysis-by-Synthesis for Fixel Recovery in Diffusion MRI
Mohamed Abouagour, Atharva Shah, Eleftherios Garyfallidis
Diffusion MRI microstructure fitting is nonconvex and often performed voxelwise, which limits fiber peak recovery in narrow crossings. This work introduces PRISM, a differentiable…

SuCor: Susceptibility Distortion Correction via Parameter-Free and Self-Regularized Optimal Transport
Sreekar Chigurupati, Eleftherios Garyfallidis
We present SuCor, a method for correcting susceptibility induced geometric distortions in echo planar imaging (EPI) using optimal transport (OT) along the phase encoding direction.…

Spatially Regularized Super-Resolved Constrained Spherical Deconvolution (SR-CSD) of Diffusion MRI Data
Ekin Taskin, Gabriel Girard, Juan Luis Villarreal Haro +4
Constrained Spherical Deconvolution (CSD) is widely used to estimate the white matter fiber orientation distribution (FOD) from diffusion MRI data. Its angular resolution depends o…
