Plastic Shaping of Concentrator-Waveguide Tip for Ultrasound Endovascular Ablation
نویسندگان
چکیده
One of the most effective methods treating intravascular formations at present is use stepped ultrasonic waveguide systems a tubular type (concentrators-waveguides) with hollow spherical tip, presence which makesit possible to supply liquid media dislocation zone an formation aim additional cavitation effect and as efficiently possible. destroy due vibration impact. Based on results analysis features existing shaping for obtaining tip concentrator-waveguide, it advisable plastic deformation – expansion crimping. The paper presents preliminary calculations, numerical modeling experimental studies processes concentrator-waveguide by distribution On basis finite element method in environment ABAQUS software package, crimping pipe billet was carried out, has made to: evaluate stress-strain state deformable conical section billet, change wall thickness during forming process calculate length design section; establish patterns influence geometric parameters power modes process; set crimping, ensure required geometry. obtained calculation, have similar values, confirms correctness using both calculation development technology manufacturing concentrator-waveguide.

Planar waveguides are useful to transport, concentrate and distribute light uniformly over large dimensions. Their capacity to collect and gather light efficiently over a large distance is interesting for many applications, like backlighting and solar concentration. For these reasons, the possibility of making them even more efficient could be of considerable interest for the community. The obs...

RESULTS: Embolization was technically successful in all patients. Cornplete occlusion was achieved in 14 (67%) patients; 90% occlusion was achieved in seven (33%) patients. There was partial reperfusion of the aneurysm in three patients (14%) after 6 months, which necessitated repeated embolization. The clinical results were excellent in 13 patients, good in six, and fair in one. One patient di...

It is generally accepted that small to medium level concentrators could be used as cost-competitive replacements for tracked solar panels. The objective is to design a system that can reach a good level of sun concentration with only one sun-tracking axis and is cheap to fabricate. As the most critical parameter for all concentrator designs, optical efficiency needed improvement to reduce the c...
متن کاملPlanar waveguide concentrator used with a seasonal tracker.
Solar concentrators offer good promise for reducing the cost of solar power. Planar waveguides equipped with a microlens slab have already been proposed as an excellent approach to produce medium to high concentration levels. Instead, we suggest the use of a cylindrical microlens array to get useful concentration without tracking during the day. To use only a seasonal tracking system and get th...
