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

Bundle-Specific Tractography

2018
Tractography allows the investigation of white matter fascicles. However, it requires a large amount of streamlines to be generated to cover the full spatial extent of desired bundles. In this work, a bundle-specific tractography algorithm was developed to increase reproducibility and sensitivity of white matter fascicle virtual dissection, thus ...

DTI Tractography

Theoretical and Natural Science
The DTI technology used to observe the Nerve fascicle - Nerve fascicle imaging was also discussed in detail. Two types of deterministic and probabilistic traction imaging were compared from effectiveness and computational efficiency perspectives. Then an experimental study was conducted using different software to compare the fiber bundles of the ...
