Filtered Multitensor Tractography
(Institute of Electrical & Electronics Engineers (IEEE), 2010)
We describe a technique that uses tractography to drive the local fiber model estimation. Existing techniques use independent estimation at each voxel so there is no running knowledge of confidence in the estimated model ...
A Geometry-Based Particle Filtering Approach to White Matter Tractography
(Springer Science + Business Media, 2010)
We introduce a fibre tractography framework based on a particle filter which estimates a local geometrical model of the underlying white matter tract, formulated as a `streamline flow' using generalized helicoids. The ...
A filtered approach to neural tractography using the Watson directional function
(Elsevier BV, 2010)
We propose a technique to simultaneously estimate the local fiber orientations and perform multifiber tractography. Existing techniques estimate the local fiber orientation at each voxel independently so there is no running ...
Tensor kernels for simultaneous fiber model estimation and tractography
(Wiley-Blackwell, 2010)
This paper proposes a novel framework for joint orientation distribution function (ODF) estimation and tractography based on a new class of tensor-kernels. Existing techniques estimate the local fiber orientation at each ...
Biomarkers for Identifying First-Episode Schizophrenia Patients Using Diffusion Weighted Imaging
(Springer Science + Business Media, 2010)
Recent advances in diffusion weighted MR imaging (dMRI) has made it a tool of choice for investigating white matter abnormalities of the brain and central nervous system. In this work, we design a system that detects ...
