Small Aperture Ultrasound Transducers for Intracavitary Tissue Ablation

Conference IEEE International Ultrasonics Symposium Ius · October 1, 2019 Catheter directed ultrasound (US) transducer is capable of delivering high, focused acoustic power to the target tissue inside a body. The direct interaction with the tissue enables to minimize the concern of unintended tissue damages. Despite the potentia ... Full text Cite

Elimination of cavitation-related attenuation in shock wave lithotripsy

Conference Aip Conference Proceedings · March 17, 2017 In shock wave lithotripsy (SWL), acoustic pulses with a leading compression wave followed by a tensile wave are delivered into the patient's body using a water-filled coupling cushion. Cavitation-related acoustic energy loss in the coupling unit depends cr ... Full text Cite

Characterization of jet formation and flow field produced by tandem bubbles

Conference Aip Conference Proceedings · March 17, 2017 Tandem bubble (TB) interactions have been shown to produce directional jets that can be used to create membrane poration on single cells. Jet speed and associated flow field produced around the TB have been postulated to play an important role in TB-induce ... Full text Cite

The effect of stone size on comminution efficiency in shock wave lithotripsy

Conference Aip Conference Proceedings · March 17, 2017 We have investigated the relationship between stone size and stone comminution (SC) in shock wave lithotripsy (SWL). Begostone phantoms of cylindrical shape in 4-, 7- and 10-mm size (W x H) groups were prepared with appropriately equal total mass (i.e., 1. ... Full text Cite

Respiration gating beam steering to precisely target a movable stone in shock wave lithotripsy

Conference 2015 IEEE International Conference on Cyber Technology in Automation Control and Intelligent Systems IEEE Cyber 2015 · October 2, 2015 In this study, a foam mask is introduced to elongate the beam width in the focal plane of a shock wave lithotripter, and a respiration gating beam steering strategy is proposed to accurately target stones, which are movable because of patient respiratory m ...
