In the paper the authors describe the research on thin-film surface heat sources created on flexible textile substrate. The novelty of research is included in using two technologies: physical vapour deposition and laser ablation. Two structures in form of meander and clover were implemented in Comsol Multihysics package to laser ablation optimization and to modeling of structure heating. Experiments...
Recent works in neurology have explored ways to obtain a better understanding of blood flow circulation in the brain with the ultimate goal of improving the treatment of cerebrovascular diseases, such as strokes, stenosis, and aneurysms. In this paper, we propose a framework to reconstruct three-dimensional (3D) models of intracerebral vessels from biplane angiograms. The reconstructed vessel geometries...
Stainless steel 470 Li-24 Cr and 460Li-21 Cr are two new generation super-ferritic nickel free grades, contains titanium (Ti), niobium (Nb) and very small percentage of carbon (C) and nitrogen (N). The Ti and Nb enhance the corrosion resistance while the low interstitial content of C and N leads to finer precipitates and greater ductility. These grades are economic alternative to 316L and 304 with...
Our goal is to develop a complete ultrasound platform based on real-time SAFT (Synthetic Aperture Focusing Technique) GPU processing. We are planning to integrate all the ultrasound modules and processing resources (GPU) in a single rack enclosure with the PCIe switch fabric backplane. The first developed module (RX64) provides acquisition and streaming of 64 ultrasound channels. We implemented and...
The objective of our project is to develop a complete ultrasound platform with real-time GPU processing. The platform is designed to be modular and scalable both in number of ultrasound channels (64–256), as well as in communication bandwidth and processing power. By standardizing on the PCIe switch fabric, we are planning to integrate all the ultrasound modules and processing resources (GPU) in a...
There is a continuous trend towards small and portable ultrasound systems with multichannel processing. The objective of the work was to develop a modular acquisition and processing platform based on the following architecture principles: limited hardware processing, external high-speed data communication and software based on SAFT processing using embedded graphics processing unit (GPU). The acquisition...
