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.

Real-time tractography: computation and visualization
Brain Structure and FunctionDid you know that even though tractography is often considered a computationally expensive and offline process, the latest algorithms can now be performed in real-time without sacrificing accuracy? Interactive real-time tractography has proven to be valuable in surgical planning and has the potential to enhance neuromodulation therapies, highlighting ...

SPIE Proceedings, 2012
Fiber tracking algorithms yield valuable information for neurosurgery as well as automated diagnostic approaches. However, they have not yet arrived in the daily clinical practice. In this paper we present an open source integration of the global tractography algorithm proposed by Reisert et.al.1 into the open source Medical Imaging Interaction ...

From Vesalius to tractography.
Journal of neurosurgical sciences, 2015The 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), 2018Computational 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 of the Median Nerve
Seminars in Musculoskeletal Radiology, 2009The median nerve is one of the most commonly affected peripheral nerves in various pathologies such as entrapment syndromes or transections. The diagnostic procedures applied in these situations are electromyography, physical examination methods, ultrasonography, and magnetic resonance imaging.

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

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 ...

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 ...
