Diffusion Tensor Estimation

Estimation of Positive Definite Diffusion Tensors from Diffusion Weighted MRI

Vous suivez désormais cette soumission

This script shows how to compute a Diffusion Tensor (DTI) from a given DW-MRI (Diffusion-Weighted MRI) dataset. The method guarantees that the estimated tensor is positive-definite or at least positive semi-definite. The implementation is based on the article by A. Barmpoutis and B.C. Vemuri, "A Unified Framework for Estimating Diffusion Tensors of any order with Symmetric Positive-Definite Constraints", In Proc. of ISBI, 2010.
