BM4D-PC: nonlocal volumetric denoising of principal components of diffusion-weighted MR images
Vinicius P. Campos, Diego Szczupak, Tales Santini +4
Purpose: Noise in diffusion-weighted MRI (dMRI) is often spatially correlated due to different acquisition and reconstruction strategies, which is not fully accounted for in curren…
