Diffusion MRI noise mapping using random matrix theory
PURPOSE: To estimate the spatially varying noise map using a redundant magnitude MR series. METHODS: We exploit redundancy in non-Gaussian multi-directional diffusion MRI data by identifying its noise-only principal components, based on the theory of noisy covariance matrices. The bulk of PCA eigenv...
