Accelerated Wirtinger Flow: A fast algorithm for ptychography
Rui Xu, Mahdi Soltanolkotabi, Justin P. Haldar +4
This paper presents a new algorithm, Accelerated Wirtinger Flow (AWF), for ptychographic image reconstruction from phaseless diffraction pattern measurements. AWF is based on combi…
Multidimensional Correlation Spectroscopic Imaging of Exponential Decays: From Theoretical Principles to In Vivo Human Applications
Daeun Kim, Jessica L. Wisnowski, Christopher T. Nguyen +1
Multiexponential modeling of relaxation or diffusion MR signal decays is a popular approach for estimating and spatially mapping different microstructural tissue compartments. Whil…
OEDIPUS: An Experiment Design Framework for Sparsity-Constrained MRI
Justin P. Haldar, Daeun Kim
This paper introduces a new estimation-theoretic framework for experiment design in the context of MR image reconstruction under sparsity constraints. The new framework is called O…
