Improving the sensitivity of tractography using microstructure modeling and pseudo-inversion
Original language description
Tractography is a method to map white matter bundles within brain tissue based on diffusion MRI techniques. It seems to be a promising way of detecting white matter structure in vivo, however, method seems to be prone to false positives if standard methods of tractography are used. The paper promises to explore the possibilities of optimization techniques which would enable to include more informative models to the tractography procedure by filtering out false positives from a set of candidate tracts. To detect anatomically plausible tracts, inverse problem from matrix equation y=Ax is solved with help of pseudo-inversion technique. However, pseudo-inversion seems to be an anappropriate for system of such dimensions and conditioning.
