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 ...

Global tractography

Tractography aims to infer, from a series of diffusion MRI images of the brain, the trajectories of the axonal fibers that generated them; however, as the typical size of the axons is much smaller than the spatial resolution attainable with MRI, this estimation process is ill-posed.

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 ...

Filtered tractography.

2010
Computer vision encompasses a host of computational techniques to process visual information. Medical imagery is one particular area of application where data comes in various forms: X-rays, ultrasound probes, MRI volumes, EEG recordings, NMR spectroscopy, etc.
