Background interference on the color of dental composite materials with different thickness by digital contrast
(2007-08-31)
In this work the color dependence of resin composites with the background color was evaluated. The objective was to measure since what thickness the color of the sample stops being influenced by the color of the background ...

Synergistic multi-contrast cardiac magnetic resonance image reconstruction
(ROYAL SOC, 2021)
Cardiac magnetic resonance imaging (CMR) is an important tool for the non-invasive diagnosis of a variety of cardiovascular diseases. Parametric mapping with multi-contrast CMR is able to quantify tissue alterations in ...
Multiple imaging radiography at LNLS
(ELSEVIER SCIENCE BVAMSTERDAM, 2008)
An analyzer-based X-ray phase-contrast imaging (ABI) setup has been mounted at the Brazilian Synchrotron Light Laboratory (LNLS) for multiple imaging radiography (MIR) purposes. The algorithm employed for treating the MIR ...
Controle de qualidade em raios x digital: iImpacto na resolução espacial e de contraste da imagem aplicando as mudanças de filtros por região anatômica
(Universidade Tecnológica Federal do ParanáCuritibaBrasilTecnologia em RadiologiaUTFPR, 2017-02-16)
This study performs an analysis on quality control in digital images through tests made with image plates (IPs) in the digital radiology sector using TOR CDR phantom. This phantom allows the evaluation of several parameters ...
