High Angular Resolution Diffusion Imaging (HARDI) Tutorial
Date: 02/02/2012
Description:
A tutorial on analyzing high-angular resolution diffusion imaging (HARDI) data. I’ll mainly focus on the practical aspects of data analysis, including preprocessing steps, model fitting, and analysis. I’ll also go over some of the analysis tools that I use, such as MRtrix, mrDiffusion and dipy, and give practical examples from each of them.
