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 ...

BSLIM: Spectral Localization by Imaging with Explicit $ B _{ 0 } $ Field Inhomogeneity Compensation

Michaël Unser, Mathews Jacob, Dimitri Nestor Alice Van De Ville, Ildar Khalidov

Magnetic resonance spectroscopy imaging (MRSI) is an attractive tool for medical imaging. However, its practical use is often limited by the intrinsic low spatial resolution and long acquisition time. Spectral localization by imaging (SLIM) has been propos ...

3-D Shape Estimation of DNA Molecules from Stereo Cryo-Electron Micro-Graphs Using a Projection-Steerable Snake

Michaël Unser, Thierry Blu, Mathews Jacob

We introduce a three-dimensional (3-D) parametric active contour algorithm for the shape estimation of DNA molecules from stereo cryo-electron micrographs. We estimate the shape by matching the projections of a 3-D global shape model with the micrographs; ...

Improved MRSI with Field Inhomogeneity Compensation

Michaël Unser, Mathews Jacob, Dimitri Nestor Alice Van De Ville, Ildar Khalidov

Magnetic resonance spectroscopy imaging (MRSI) is a promising and developing tool in medical imaging. Because of various difficulties imposed by the imperfections of the scanner and the reconstruction algorithms, its applicability in clinical practice is r ...

3D Reconstruction and Comparison of Shapes of DNA Minicircles Observed by Cryo-Electron Microscopy

Michaël Unser, Andrzej Stasiak, Mathews Jacob, Arnaud Amzallag

We use cryo-electron microscopy to compare 3D shapes of 158 bp long DNA minicircles that differ only in the sequence within an 18 bp block containing either a TATA box or a catabolite activator protein binding site. We present a sorting algorithm that corr ...

Three-Dimensional Feature Detection Using Optimal Steerable Filters

Michaël Unser, Mathews Jacob, François Aguet

We present a framework for feature detection in 3-D using steerable filters. These filters can be designed to optimally respond to a particular type of feature by maximizing several Canny-like criteria. The detection process involves the analytical computa ...
