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 ...

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 ...

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 ...

Echo planar imaging with a contrast medium in studying brain perfusion
Echo planar imaging is a new MRI technique capable of producing images in short periods of time. This type of examination has the time resolution required to study the first passage of contrast medium through ...
