Diffusion-Tensor Magnetic Resonance Imaging (DT-MRI) is a relatively recent
imaging modality. DT-MRI images are measurements of the diffusion tensor of
water in each voxel of an imaging volume. They can be viewed as noisy,
discrete, voxel-averaged samples of a continuous function from 3D space into
the positive definite symmetric matrices. These DT-MRI images can be used to
probe the structural and architectural features of fiber tissue such white
matter and the heart ventricles. We will present an overview of the
problems, methods and applications associated with DT-MRI data and their
