Entorhinal and transentorhinal atrophy in preclinical Alzheimer's disease
This work discusses atrophy in the medial temporal lobe during the progression of early Alzheimer's disease.
infinitesimal drift diffeomorphometry models for population shape analysis
This work discusses time dependent models of shape changes to study neurodegeneration.
Coarse-to-Fine Hamiltonian Dynamics of Hierarchical Flows in Computational Anatomy
We developed optimal control formulations for parameterizing deformations and features described at multiple scales. This work is contributing to brain atlasing initatives for microscopy images.
Diffeomorphic Upsampling of Serially Acquired Sparse 2D Cross-Sections in Cardiac MRI
We design diffeomorphic techniques to estimate unobserved data between sparsely sampled slices in cardiac MRI.
Estimating diffeomorphic mappings between templates and noisy data: Variance bounds on the estimated canonical volume form
We derived the Cramer Rau bound for estimating volume changes from deformable image registration, which is a lower bound on the variance of an estimator. We demonstrated its implications for image registration performance in asymmetric methods versus symmetric methods, the former generally performing better.
