Description

Diffusion Tensor Estimation by Maximizing Rician Likelihood.

Notes

Diffusion Tensor Estimation by Maximizing Rician Likelihood.Tensor Estimation while taking into account the joint
distribution of all observed data in the context of an
augmented tensor model to account for variable levels of
Rician noise.
Inputs:
-DWI and Reference Image(s) Data (4D file collection)
-Table of diffusion weighting directions (file)
-Table of b-values (file)
-Table of k-Space Average (file)
-Mask Volume to Determine Region of Tensor Estimation (3D file, optional)
-Noise Field (3D file, optional)
-Constant Noise Level (float)
