Toward global tractography

NeuroImage, 2013
Diffusion-based tractography is an ill-posed problem, because the step-by-step reconstruction of a fibre bundle trajectory cannot afford any serious mistake in the evaluation of the local fibre orientations. Such evaluation is difficult, however, because the myriad fibres passing through a single voxel follow different directions.

Validation of Tractography

2009
The validation of tractography is fundamental to the implementation of the technique as a useful biomedical tool. The technique has the potential to help in the diagnosis of patients suffering from brain injury and disease, as well as providing insights into basic neuroscience.

Fast Approximate Stochastic Tractography

Neuroinformatics, 2011
Many different probabilistic tractography methods have been proposed in the literature to overcome the limitations of classical deterministic tractography: (i) lack of quantitative connectivity information; and (ii) robustness to noise, partial volume effects and selection of seed region.

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.

Real-time tractography: computation and visualization

Brain Structure and Function
Did 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 ...

MITK global tractography

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, 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 of the Median Nerve

Seminars in Musculoskeletal Radiology, 2009
The 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.
