    Uncinate fasciculus fiber tracking in mesial temporal lobe epilepsy. Initial findings

    In temporal lobe epilepsy (TLE) due to hippocampal sclerosis (HS), ictal discharge spread to the frontal and insulo-perisylvian cortex is commonly observed. The implication of white matter pathways in this pro...

    MR Diffusion-Based Inference of a Fiber Bundle Model from a Population of Subjects

    This paper proposes a method to infer a high level model of the white matter organization from a population of subjects using MR diffusion imaging. This method takes as input for each subject a set of trajecto...

    Fiber Tracking in q-Ball Fields Using Regularized Particle Trajectories

    Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel. New e...

    A Spin Glass Based Framework to Untangle Fiber Crossing in MR Diffusion Based Tracking

    We propose a general approach to the reconstruction of brain white matter geometry from diffusion-weighted data. This approach is based on an inverse problem framework. The optimal geometry corresponds to the ...

    Regularization of MR diffusion tensor maps for tracking brain white matter bundles

    We propose a new way for tracking brain white matter fiber bundles in diffusion tensor maps. Diffusion maps provide information about mobility of water protons in different directions. Assuming that diffusion ...
