Optimized weighting for Fourier rebinning of three-dimensional time-of-Flight PET data to non-time-of-flight
TL;DR: This paper addresses the question of optimal rebinning in order to make full use of TOF information and consequently to maximize image quality and focuses on FORET-3D, which rebins 3D TOF data into 3D non-TOF sinogram formats without requiring a Fourier transform in the axial direction.
Journal ArticleDOI
Lower white matter volume in beta-thalassemia associated with anemia and cognitive performance.
Book ChapterDOI
Generating Cortical Constraints for MEG Inverse Procedures Using MR Volume Data
TL;DR: The forward problem relating the measured EEG or MEG signal and the primary current sources can be solved using a boundary element method (BEM), and the brain region for the BEM can be found using the method described here.

The equivalence of linear spherical deconvolution and model-free linear transform methods for diffusion MRI
TL;DR: This work provides a theoretical analysis of linear spherical deconvolution methods in diffusion MRI, building off of a theoretical framework that was previously developed for model-free linear transforms of the Fourier 2-sphere.
