Shock wave lithotripsy (SWL) suffers from the fact that it can produce residual stone fragments of significant size (>;2 mm). Mechanistically, cavitation has been shown to play an important role in the reduction of such fragments to smaller debris. In this study, we assessed the feasibility of using cavitationally-based pulsed ultrasound therapy (histotripsy) to erode kidney stones. Previous work...
Reliability and dependability challenges within the aerospace, military and civil aviation industries are driving the need for advances in health and usage monitoring technology. One promising method with the potential to complement conventional inspection and electrical test techniques for wiring is acoustic methods. In this paper modelling and experimental results for acoustic signal propagation...
Histotripsy is a well-controlled ultrasonic tissue ablation technology that mechanically and progressively fractionates soft tissue using cavitation. Significant ultrasound backscatter reduction occurs as the tissue in the treated volume is fractionated. This paper studies the quantitative correlation between the degree of histotripsy-induced tissue fractionation, as indicated by the percentage of...
Wiring onboard of legacy aircraft is becoming a liability due to a prolonged use of aircraft. Testing as well as repairs and maintenance require extensive number of man-hours bringing up the costs and reducing flight time of the aircraft. There is a number of conventional electric testing methods for wire testing, yet we propose and evaluate an acoustic (mechanical) testing method. Acoustic testing...
