    Optimized diffusion gradient orientation schemes for corrupted clinical DTI data sets

    Object:A method is proposed for generating schemes of diffusion gradient orientations which allow the diffusion tensor to be reconstructed from partial data sets in clinical DT-MRI, shoul...

    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 ...

    Slice acquisition order and blood oxygenation level dependent frequency content: an event-related functional magnetic resonance imaging study

    Many event-related functional magnetic resonance imaging paradigms performed so far have been designed to study a limited part of the brain with high temporal resolution. However, event-related paradigms can b...

    Eddy-Current Distortion Correction and Robust Tensor Estimation for MR Diffusion Imaging

    This paper presents a new procedure to estimate the di.usion tensor from a sequence of diffusion-weighted images. The first step of this procedure consists of the correction of the distortions usually induced ...
