Improved tractography using asymmetric fibre orientation distributions
Diffusion MRI allows us to make inferences on the structural organisation of the brain by mapping water diffusion to white matter microstructure. However, such a mapping is generally ill-defined; for instance, diffusion measurements are antipodally symmetric (diffusion along x and -x are equal), whereas the distribution of fibre orientations within a voxel is generally not symmetric. Therefore,...
متن کاملApparent Fibre Density: A New Measure for High Angular Resolution Diffusion-Weighted Image Analysis
Introduction Numerous clinical studies have used voxel based analysis of diffusion tensor (DT) invariants, such as fractional anisotropy (FA) [1], to investigate group differences in white matter (see [2] for a review). However, results are difficult to interpret in regions with crossing fibres due to the simple Gaussian diffusion model assumed with the DT. High Angular Resolution Diffusion-wei...
متن کاملImproved probabilistic streamlines tractography by 2 order integration over fibre orientation distributions
Figure 4: whole-brain results obtained by launching from 100,000 seed points placed randomly throughout the brain, shown as a 1mm thick coronal projection. Tracks are colour-coded according to their local orientation (red: left-right; green: anterior-posterior; blue: inferior-superior). Right: a close-up of the region highlighted on the left, showing an excellent delineation of the subcortical ...
متن کاملFatigue behaviour of short fibre reinforced polyamide: morphological and numerical analysis of fibre orientation effects
The fatigue behaviour of injection moulded short fibre reinforced polymers depends upon fibre orientation, as shown in experiments conducted with notched specimens injected through different injection gates. The different fatigue behaviour is related to the different local elastic properties, as determined by the different fibre orientation patterns, resulting into different strain distribution...
متن کاملA Family of Symmetric Distributions on the Circle
We propose a new family of symmetric unimodal distributions on the circle which contains the uniform, von Mises, cardioid and wrapped Cauchy distributions, amongst others, as special cases. The basic form of the densities of this family is very simple, although its normalisation constant involves an associated Legendre function. The family of distributions can also be derived by conditioning an...
