A Robust Fiber Tracking Method in Diffusion Tensor Imaging

摘要

Diffusion tensor imaging (DTI) can be used to study the evolving pathology in the central nervous system by tracking the nerve fibers.To explore a technique for overcoming the obstacles associated discretized nerve fiber images and to find the most likely directions of nerve fibers,we presented a new robust fiber tracking method in diffusion tensor imaging.The robustness lies in that it includes three situations and the joint utilization of the preference direction determined by tensor analysis,the fractional anisotropy values,and the previous propagation directions.Based on fiber tracing with a DTI dataset,we demonstrated the water diffusing patterns and fiber bundle tracks in a brain.This technique is expected to find use in the understanding of brain structure and the image-guided brain surgery.
