We propose a new algorithm for diffusion tensor reconstruction based on the robust least median squares estimator. The developed method allows one to determine the outliers that may appear due to physiological noise or other tissue-related singularities. This feature and the stability of the least median squares to noise level variation yield a new and very promising approach in research and in clinical practice.
