Design, performance analysis, and optimization of a new X-ray detector for region of interest angiography and fluoroscopy for implementation in neurovascular interventional procedures
Image guided neuro-interventions require high spatial resolution, about 4 to 10 lp/mm, for visualization of small vessels called perforators which maybe 50-300 μ m in diameter, and for precise localization of interventional ...
Design, x-ray image guidance and flow characterization of new asymmetric vascular stents
Recent advances of x-ray imaging techniques have made possible improvement and development of new minimally invasive image guided interventions (IGI). Capabilities such as real-time, high special resolution image guidance ...
Photonic crystal based optical circuitry
This work focuses on the microfabrication and nanofabrication of structures in three-dimensional photonic crystals and their exploitation in optical circuitry. We have shown microfabrication of defect structures such as ...
Molecular simulation study of fundamental effects of molecular association on properties of fluid interfaces
Fluids with molecular association such as hydrogen bonding often exhibit a variety of anomalous properties. An extreme example is hydrogen fluoride (HF), in which properties are dominated by the formation of clusters in ...
Determination of three-dimensional structured objects, vascular structures, and imaging geometry from single-plane and biplane projection images
Three-dimensional (3D) vessel trees can provide useful visual and quantitative information during interventional procedures. To calculate the 3D vasculature and improve these measurements, we have developed methods for the ...
Optimization of second-phase spatial sampling using auxiliary information
In spatial sampling, once initial samples of the primary variable have been collected, it is possible to take additional measurements at other locations, an approach known as second-phase sampling. In this dissertation, ...
