Optimizing dual-energy CT technique for iodine-based contrast-to-noise ratio
Fatma Terzioglu, Emil Y. Sidky, Jp Phillips +3
Purpose: This study proposes a systematic method for determining the optimal x-ray tube settings/energy windows and fluence for minimal noise and maximum CNR in material density im…
4D-image reconstruction directly from limited-angular-range data in continuous-wave electron paramagnetic resonance imaging
Zheng Zhang, Boris Epel, Buxin Chen +5
Objective: We investigate and develop optimization-based algorithms for accurate reconstruction of four-dimensional (4D)-spectral-spatial (SS) images directly from data collected o…
Simultaneous activity and attenuation estimation in TOF-PET with TV-constrained nonconvex optimization
Zhimei Ren, Emil Y. Sidky, Rina Foygel Barber +2
An alternating direction method of multipliers (ADMM) framework is developed for nonsmooth biconvex optimization for inverse problems in imaging. In particular, the simultaneous es…
