A statistical framework for the classification of tensor morphologies in diffusion tensor images.
Tractography algorithms for diffusion tensor (DT) images consecutively connect directions of maximal diffusion across neighboring DTs in order to reconstruct the 3-dimensional trajectories of white matter tracts in vivo in the human brain. The performance of these algorithms, however, is strongly influenced by the amount of noise in the images and by the presence of degenerate tensors-- i.e., t...

متن کاملPropagation Framework for Diffusion Tensor Imaging via Diffusion Tensor Error Propagation Framework for Diffusion Tensor Imaging via Diffusion Tensor Representations
This preprint is made available because the published work cited below had several infelicities due to production error, i.e., awkward layout of equations and font styles. The conversion from the Words document here to IEEE TMI format was a mess. Abstract An analytical framework of error propagation for diffusion tensor imaging (DTI) is presented. Using this framework, any uncertainty of intere...
متن کاملA Riemannian Framework for Denoising Diffusion Tensor Images
Diffusion Tensor Imaging (DTI) is a relatively new imaging modality that has been extensively used to study diffusion processes in the brain and has applications ranging from diagnostic to surgical planning. However, DTI imaging systems are highly sensitive to noise, leading to reconstructed images with low SNR. Thus, there is a need for image denoising algorithms specifically designed to regul...
متن کاملGeometric statistical processing of brain diffusion tensor images
Nowadays, the functioning of the human brain is still one of the biggest mysteries of humanity. The multiple holes in the understanding of the human brain explain why an intensification of brain-oriented research can be observed since a few years. One of the most recent techniques to better understand the brain is Diffusion Tensor Imaging (DTI), a noninvasive imaging modality that provides info...
