WebRidgelets S2LET supports the spherical ridgelet transform developed in McEwen & Price (2024). The ridgelet transform is defined natively on the sphere, probes signal content … WebOur method, gSlider-SR, uses a basis of Spherical-Ridgelets to exploit the redundancy of the dMRI data, while at the same time enhancing SNR. We demonstrate that only ten minutes are needed to reconstruct 64 diffusion directions (b=2000s/mm 2) at 860 μm data with reliably signal preservation.
