Image Quality Analysis in Dual-Source CT
Dual Source CT (DSCT) is new CT medical application, in which three sets of image data can be obtained by two independent X ray tubes to achieve a better tissue differentiation. In the present work, the noise, low contrast and high resolution behavior is measured for the Siemens DSCT system …

Characterization of The Count Rate Performance and Evaluation of The Effects of High Count Rates On Modern Gamma Cameras
… using established methods (Decay and Dual Source) under a variety of experimental conditions. For the Decay method, input count rate was plotted against observed count rate and fit to the paralyzable detector model (PDM) to estimate τ (Rates method). A novel expression for observed …

Synthesis and characterisation of CdS and PbS nanoparticles in an imidazolium based ionic liquid
… and the injection protocol using single and dual source precursors. Cadmium ethyl xanthate was used as single source precursor whereas cadmium acetate and dodecanethiol were used as dual source molecular precursors in the presence of 1-ethyl-3-methylimidazolium methanesulfonate ionic liquid. …

The effects of competition on defense contractor pricing behavior
… with competition. Pricing data for five dual source subsystems of the AIM-9M Sidewinder missile were examined. Key findings of the study include: • The introduction of a second source led to increased price reductions by the first source; • The first source exhibited a greater price …

Business case analysis of the Joint Strike Fighter's alternate engine program
… engine program. It compares the competition (dual-source) and sole-source scenarios with regards to the development, production, and life-cycle sustainment of the JSF engine. The study also explores past Department of Defense (DoD) engine acquisition programs, including the highly successful …

Deposition and properties of Co- and Ru-based ultra-thin films
… implemented in the interconnect. Using a dual-source chemistry of dicobaltoctacarbonyl and trimethylphosphine at temperatures from 250-350 °C, amorphous cobalt-phosphorus can be deposited by chemical vapor deposition. The films contain elemental cobalt and phosphorus, plus some carbon …

Hepatocellular Carcinoma Image-Guided Intervention: Quantitative Characterization of Reagents For Thermochemical Ablation
… image guidance.</p> <p>Quantitative dual-energy computed tomography (DECT) imaging with cationic cesium (Cs<sup>+</sup>) as a theranostic was also evaluated for TCA image guidance. DECT high- and low-energy data was acquired of Cs<sup>+</sup> standards in a commercial phantom to …
