Detailed Description

template<typename TComponent>
class itk::DiffusionTensor3D< TComponent >

Represent a diffusion tensor as used in DTI images.

This class implements a 3D symmetric tensor as it is used for representing diffusion of water molecules in Diffusion Tensor Images.

This class derives from the SymmetricSecondRankTensor, inheriting most of the Tensor-related behavior. At this level we add the methods that are specific to 3D and that are closely related to the concept of diffusion.

This class was mostly based on files that Jeffrey Duda, Torsten Rohlfing and Martin Styner contributed to the ITK users list during a discussion on support for DiffusionTensorImages. A discussion on the design of this class can be found in the WIKI pages of NAMIC:
