Use of single photon emission computed tomography and magnetic resonance to evaluate central nervous system involvement in patients with juvenile systemic lupus erythematosus
(Associação Brasileira de Divulgação Científica, 2002-07-01)
The objective of the present study was to identify the single photon emission computed tomography (SPECT) and magnetic resonance (MR) findings in juvenile systemic lupus erythematosus (JSLE) patients with CNS involvement ...
String-averaging expectation-maximization for maximum likelihood estimation in emission tomography
(Iop Publishing Ltd, 2014-05-01)
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 ...

Isotropic versus anisotropic techniques in cardiac computed tomography images processing
(IOP Publishing, 2019)
The objective of the work is to compare the performance of two filters, one isotropic
and another one of anisotropic diffusion based on gradient. To do this, experiments are carried
out to establish which of the filters ...
