Fast Tractography Streamline Search

2021
In this work, a new hierarchical approach is proposed to efficiently search for similar tractography streamlines. The proposed streamline representation enables the use of binary search trees to increase the tractography clustering speed without reducing its accuracy.

From Vesalius to tractography.

Journal of neurosurgical sciences, 2015
The description of an anatomical specimen may look straightforward, but it appears that it depends in fact on several intermingled factors: technical methods for conservation, dissection and vascular injection and the anatomist skills are of course important. This is especially true when the studied organ, as for instance the brain, is subject to rapid

Tractography Analysis for Electroconvulsive Therapy

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
Computational human head models have been used in electrophysiological studies, and they have been able to provide useful information that is unable or difficult to acquire from experimental or imaging studies. However, most of these models are purely volume conductor models that overlooked the electric excitability of axons in the white matter of the ...

Tractography visualization

Diffusion magnetic resonance imaging tractography is a powerful imaging technique that allows for the visualization of white matter tracts in the brain. This technique has become increasingly important in recent years as a way to study the structural connectivity of the brain and to investigate a wide range of neurological disorders.

Think deep in the tractography game: deep learning for tractography computing and analysis

Brain Structure and Function
Tractography is a challenging process with complex rules, driving continuous algorithmic evolution to address its challenges. Meanwhile, deep learning has tackled similarly difficult tasks, such as mastering the Go board game and animating sophisticated robots.

The Biological Basis of Diffusion Tractography

3rd IEEE International Symposium on Biomedical Imaging: Macro to Nano, 2006., 2006
The magnitude and preferred direction of water molecule motion (i.e. diffusion) in a tissue measured by magnetic resonance imaging (MRI) is dependent on the underlying micro-structure. There is considerable difference in the water diffusion properties between the two major classes of tissue in the brain, the nearly isotropic gray matter CPUs and the ...

Geodesic tractography

Differential geometry is an established framework for handling curves and surfaces. It is therefore natural to regard the problem of tractography from this perspective. In geodesic tractography, tentative tracts are operationally defined as (locally) shortest paths relative to some data-adaptive notion of length or cost. In a broader sense, it includes

Quantitative tractography: joys and sorrows

Brain Structure and Function
Quantitative tractography is the term used to indicate informing the estimation of the major axonal pathways of the brain from diffusion MRI with microstructural information (such as volume, myelin, axonal densities, etc.) to deliver veridical and biologically meaningful connectomes.

Nerve Pathways with MR Tractography

2006
Conventional and morphometric magnetic resonance (MR) techniques provide an accurate representation of the brain’s anatomy at a macroscopic scale, but they do not provide information on the topography of white matter bundles. The study of the anisotropic diffusion of water molecules (diffusion tensor imaging; DTI) and tractography (fibre tracking ...
