Distributing points uniformly on the unit sphere under a mirror reflection symmetry constraint
Cheng Guan Koay
Uniformly distributed point sets on the unit sphere with and without symmetry constraints have been found useful in many scientific and engineering applications. Here, a novel vari…
Conceptual Foundations of Diffusion in Magnetic Resonance
Cheng Guan Koay, Evren Özarslan
A thorough review of the q-space technique is presented starting from a discussion of Fick's laws. The work presented here is primarily conceptual, theoretical and hopefully pedago…
Sparse and Optimal Acquisition Design for Diffusion MRI and Beyond
Cheng Guan Koay, Evren Özarslan, Kevin M Johnson +1
The focus of this paper is on the development of a sparse and optimal acquisition (SOA) design for diffusion MRI multiple-shell acquisition and beyond. A novel optimality criterion…
Pseudometrically Constrained Centroidal Voronoi Tessellations: Generating uniform antipodally symmetric points on the unit sphere with a novel acceleration strategy and its applications to Diffusion and 3D radial MRI
Cheng Guan Koay
Purpose: The purpose of this work is to investigate the hypothesis that uniform sampling measurements that are endowed with antipodal symmetry play an important role when the raw d…
