Predicting the Brain Injury Effects on Physical Arrangement of White Matter Neuronal Tracts using a Finite Element Head Model based on Tractography, Ph.D. Dissertation Sharif University of Technology ; Farahmand, Farzam (Supervisor) ; Shamloo, Amir (Co-Supervisor) ; Oghabian, Mohammad Ali (Co-Supervisor)
Abstract
Diffuse tensor imaging or tractography is a useful method for tracking the axonal tracts pathways within the brain white matter by monitoring the movements of water molecules along the axons. The higher the level of the tissue anisotropy, the more accurate the pathways can be estimated. But in the swelling regions around an edematous tumor, the excess of watery fluid disrupts the directional movement of water molecules, and consequently, the diffuse tensor imaging is unable to track the pathways. This impairment should be resolved by predicting the axontal tracts arrangement in the blind regions of the images using the numerical modeling. To this end, a finite element model of the human...
