Main Paths of Brain Fibers in Diffusion Images Mixed with a Noise to Improve Performance of Tractography Algorithm-Evaluation in Phantom [PDF]

Journal of Biomedical Physics and Engineering
Background: Some voxels may alter the tractography results due to unintentional alteration of noises and other unwanted factors.Objective: This study aimed to investigate the effect of local phase features on tractography results providing data are mixed

Optimum Diffusion Encoding Steps for Fiber Tractography

, 2006
This work investigated the number of diffusion gradient steps in diffusion tensor imaging (DTI) that is optimum for fiber tractography. We quantified the effect of gradient encoding steps on the tractography in terms of a coherence index.

Probabilistic Clustering and Shape Modelling of White Matter Fibre Bundles using Regression Mixtures [PDF]

We present a novel approach for probabilistic clustering of white matter fibre pathways using curve-based regression mixture modelling techniques in 3D curve space. The clustering algorithm is based on a principled method for probabilistic modelling of a

Combining DTI and fMRI to investigate language lateralisation [PDF]

, 2013
Hemispheric lateralisation in the human brain has been a focus of interest in different fields of neurosciences since a long time (Galaburda, LeMay, Kemper, & Geschwind, 1978; Rubino, 1970).
