Investigation of iterative image reconstruction in three-dimensional optoacoustic tomography
, 2012 Iterative image reconstruction algorithms for optoacoustic tomography (OAT), also known as photoacoustic tomography, have the ability to improve image quality over analytic algorithms due to their ability to incorporate accurate models of the imaging ...

A Novel Kernel-Based Regularization Technique for PET Image Reconstruction
Technologies, 2017 Positron emission tomography (PET) is an imaging technique that generates 3D detail of physiological processes at the cellular level. The technique requires a radioactive tracer, which decays and releases a positron that collides with an electron ...

Parallel extragradient-proximal methods for split equilibrium problems [PDF]
, 2015 In this paper, we introduce two parallel extragradient-proximal methods for solving split equilibrium problems. The algorithms combine the extragradient method, the proximal method and the hybrid (outer approximation) method.

Parameter-independent Iterative Approximate Byzantine Consensus [PDF]
, 2012 In this work, we explore iterative approximate Byzantine consensus algorithms that do not make explicit use of the global parameter of the graph, i.e., the upper-bound on the number of faults ...

Topological Value Iteration Algorithms
, 2011 Value iteration is a powerful yet inefficient algorithm for Markov decision processes (MDPs) because it puts the majority of its effort into backing up the entire state space, which turns out to be unnecessary in many cases. In order to overcome this problem, many approaches have been proposed.
