Tractography passes the test: Results from the diffusion-simulated connectivity (disco) challenge

Jean-Philippe Thiran, Alessandro Daducci, Ying-Chia Lin, Sara Sedlar, Caio Seguin, Gabriel Girard, Erick Jorge Canales Rodriguez, Alonso Ramirez Manzanares, Marco Pizzolato, Juan Luis Villarreal Haro, Kenji Marshall, Yang Ji

Estimating structural connectivity from diffusion-weighted magnetic resonance imaging is a challenging task, partly due to the presence of false-positive connections and the misestimation of connection weights. Building on previous efforts, the MICCAI-CDMR ...

Robust Monte-Carlo Simulations in Diffusion-MRI: Effect of the Substrate Complexity and Parameter Choice on the Reproducibility of Results

Jean-Philippe Thiran, David Paul Roger Romascano, Gabriel Girard, Jonathan Rafael Patino Lopez, Erick Jorge Canales Rodriguez, Alonso Ramirez Manzanares

Monte-Carlo Diffusion Simulations (MCDS) have been used extensively as a ground truth tool for the validation of microstructure models for Diffusion-Weighted MRI. However, methodological pitfalls in the design of the biomimicking geometrical configurations ...

Robust compressive sensing of sparse signals: A review

Rafael Eduardo Carrillo Rangel, Alonso Ramirez Manzanares

Compressive sensing generally relies on the L2-norm for data fidelity, whereas in many applications robust estimators are needed. Among the scenarios in which robust performance is required, applications where the sampling process is performed in the prese ...

An overview of robust compressive sensing of sparse signals in impulsive noise

Rafael Eduardo Carrillo Rangel, Alonso Ramirez Manzanares

While compressive sensing (CS) has traditionally relied on L2 as an error norm, a broad spectrum of applications has emerged where robust estimators are required. Among those, applications where the sampling process is performed in the presence of impulsiv ...

Quantitative comparison of reconstruction methods for intra-voxel fiber recovery from diffusion MRI

Gloria Menegaz, Jean-Philippe Thiran, Mathews Jacob, Yves Wiaux, Alessandro Daducci, Ying-Chia Lin, Maxime Descoteaux, Erick Jorge Canales Rodriguez, Alonso Ramirez Manzanares

Validation is arguably the bottleneck in the diffusion MRI community. This paper evaluates and compares 20 algorithms for recovering the local intra-voxel fiber structure from diffusion MRI data and is based on the results of the "HARDI reconstruction chal ...
