Modeling diffusion directions of Corpus Callosum
conference contribution
posted on 2017-05-16, 10:05 authored by Safa Elsheikh, Andrew Fish, Roma Chakrabarti, Diwei ZhouDiwei Zhou, Mara CercignaniDiffusion Tensor Imaging (DTI) has been used to study the characteristics of Multiple Sclerosis (MS) in the brain. The von Mises-
Fisher distribution (vmf) is a probability distribution for modeling directional
data on the unit hypersphere. In this paper we modeled the diffusion directions of the Corpus Callosum (CC) as a mixture of vmf
distributions for both MS subjects and healthy controls. Higher diffusion
concentration around the mean directions and smaller sum of angles between the mean directions are observed on the normal-appearing CC of the MS subjects as compared to the healthy controls.
