String-averaging expectation-maximization for maximum likelihood estimation in emission tomography
(IOP PublishingBristol, 2014-04-17)
We study the maximum likelihood model in emission tomography and propose a new family of algorithms for its solution, called string-averaging expectation-maximization (SAEM). In the string-averaging algorithmic regime, the ...
Estudo longitudinal para avaliar a evolucao clinica e arteriografica de pacientes com Arterite de Takayasu submetidos ao PET-CT com 18F-FDG
