Computer-based automated estimation of breast vascularity and correlation with breast cancer in DCE-MRI images
(2017)Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with gadolinium constitutes one of the most promising protocols for boosting up the sensitivity in breast cancer detection. The aim of this study was twofold: ... -
Conductivity of Gd-doped BaCeO3 protonic conductor in H2-H2O-O2 atmospheres
(2013)This work proposes a radically new simple method of evaluation of the proton conductivity based on measurement of the conductivity of ceramic materials depending on the oxygen partial pressure (pO2) at a gradual transition ... -
The effect of cobalt oxide addition on the properties of gadolinium doped barium cerate
(2009)In the present work the effect of cobalt oxide addition on the density and on the electrical properties of gadolinium doped barium cerate is investigated. A series of BaCe0.9-xGd0.1CoxO3-δ (?=0.00, 0.01, 0.03, 0.05, 0.07, ... -
Effect of dopants on CeO2 based solid state electrolytes for intermediate temperature electrochemical devices
(2011)The present work aims at the investigation of the influence of different dopants' ionic radii and their concentration on both the lattice parameters and the density of Ce1-xLnxO2-δ (x = 0-0.20; Ln = La, Nd, Sm, Eu, Gd, Dy, ... -
A modified Seeded Region Growing algorithm for vessel segmentation in breast MRI images for investigating the nature of potential lesions
(2014)The role of Magnetic Resonance Imaging (MRI) as an alternative protocol for screening of breast cancer has been intensively investigated during the past decade. Preliminary research results have indicated that gadolinium-agent ... -
MRI simulation-based evaluation of ECV calculation using MOLLI T1 maps
(2015)Quantification of myocardial extracellular volume (ECV) fraction based on pre- and post-gadolinium MOLLI T1 maps is a research tool that has the potential to become an important prognostic tool for assessing specific ... -
A Sub-Sampling Approach for Data Acquisition in Gamma Ray Emission Tomography
(2016)State of the art data acquisition systems for small animal imaging gamma ray detectors often rely on free running Analog to Digital Converters (ADCs) and high density Field Programmable Gate Arrays (FPGA) devices for digital ... -
Tissue characterization: T1, t2 andt2* techniques
(2015)Noninvasive characterization of tissue has long been the unique domain of magnetic resonance imaging (MRI) when compared to other imaging modalities. Techniques for such typically emphasize one or more MR-based relaxation ...
