TDF-TRACT: Probabilistic tractography using the tensor distribution function
Fractional anisotropy (FA), a widely used measure of fiber integrity based on diffusion tensor imaging (DTI), is theoretically confounded by several other quantities including the...

Modelling Noise-Induced Fibre-Orientation Error in Diffusion-Tensor MRI
Diffusion-Tensor MRI can be used to measure fibre orientation within the brain. Several studies have proposed methods to reconstruct known white matter fibre tracts in the brain. ...

Validation and regularization in diffusion MRI tractography
We present a physical phantom designed for fibre tractography validation and use it to evaluate tracking algorithms that employ (a) the classic diffusion tensor model of diffusion...

A Geometry-Based Particle Filtering Approach to White Matter Tractography
Abstract. 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 ...

Probabilistic multi-tensor estimation using the Tensor Distribution Function
Diffusion weighted magnetic resonance (MR) imaging is a powerful tool that can be employed to study white matter microstructure by examining the 3D displacement profile of water m...
