Objective: Provide a way for noise removal in diffusion weighted images incorporating the Rician noise model. The Rician noise level is estimated automatically and used to parametrize the local Linear Minimum Mean Squared Error estimator.

Progress: The method was evaluated on real and synthetic datasets. A Slicer 3 module was developed.
