Metal artifact reduction strategies for improved attenuation correction in hybrid PET/CT imaging

Metallic implants are known to generate bright and dark streaking artifacts in x-ray computedtomography (CT) images, which in turn propagate to corresponding functional positron emissiontomography (PET) images during the CT-based attenuation correction procedure commonlyused on hybrid clinical PET/CT scanners. Therefore, visual artifacts and overestimation and/orunderestimation of the tracer uptake in regions adjacent to metallic implants are likely to occur andas such, inaccurate quantification ...

The need for economy of translation found in sub ...

Numerical modeling of non-isothermal reduction of a porous wustite pellet with Syngas

Abstract
A non-isothermal transient model has been developed to simulate the reduction process
and thermal behaviors of a porous wustite pellet undergoing chemical reactions with a
mixture of hydrogen, carbon monoxide, water vapor and carbon dioxide which is
commonly named Syngas. The model describes the chemical reaction itself, the mass
balance for each gaseous species and the energy equation within the pellet. For solution of
the governing equations, a Computational Fluid Dynamic (CFD) ...
