Optimal Experimental Design for Biophysical Modelling in Multidimensional Diffusion MRI

Published in MICCAI, 2019

This paper shows that combining LTE and PTE maximizes precision in the estimation of the tensors in the cumulant expansion.

Resolving degeneracy in diffusion MRI biophysical model parameter estimation using double diffusion encoding

Published in Magnetic Resonance in Medicine, 2019

This paper shows that incorporating double diffusion encoding (DDE) measurements help resolve the degeneracy in the parameter estimation for the Standard Model of diffusion in white matter for a Watson fiber distribution function (ODF). This is also the case for an arbitrary ODF, as was later proved.
