Module denoise

Module denoise 

Source
Expand description

MP-PCA denoising for multi-volume data (e.g. multi-echo magnitude).

Random-matrix-theory denoising (Veraart 2016) that removes noise along the volume dimension while preserving spatial edges. Applying [mppca_denoise] to multi-echo magnitude before R2*/R2 fitting reduces relaxation-rate variance without blurring structure.

Functions§

mppca_denoise
Denoise multi-volume data with MP-PCA.
