Geodesic ray-tracing in white matter fiber crossing region using decomposition of 4th order tensor
(The International Society for Optical Engineering (SPIE), 2021)
The streamline methods in Diffusion tensor imaging (DTI) use principal eigenvectors for tracking white matter fibers. In comparison, the geodesics in a multivalued ray-tracing method are closer to the actual underlying ...
Potential Biomarkers From Positive Definite 4th Order Tensors In Hardi
(IEEE Signal Processing Society, 2021)
In this paper, we provide a framework to evaluate new scalar quantities for higher order tensors (HOT) appearing in high angular resolution diffusion imaging (HARDI). These can potentially serve as biomarkers. It involves ...
