Ultrasound is used in many medical applications, such as imaging, blood flow analysis,
dentistry, liposuction, tumor and fibroid ablation, and kidney stone disruption. In the past, low …

Microbubble contrast agents and the associated imaging systems have developed over the
past 25 years, originating with manually-agitated fluids introduced for intra-coronary …

The purpose of this study was to develop a unified model capable of explaining the
mechanisms of interaction of ultrasound and biological tissue at both the diagnostic …

The Rayleigh collapse time is the time it would take to shrink an empty spherical bubble in
an infinite liquid domain to zero size, which is a function of ambient pressure and initial …

The collapse of a cavitation bubble near a rigid boundary induces a high-speed transient jet
accelerating liquid onto the boundary. The shear flow produced by this event has many …

The interfacial convection in multilayer systems is a widespread phenomenon that is of great
importance in numerous branches of technology, including chemical engineering, space …

Background: Augmentation of tissue blood flow by therapeutic ultrasound is thought to rely
on convective shear. Microbubble contrast agents that undergo ultrasound-mediated …

A power toothbrush (10) is disclosed having a handle (15) containing a rechargeable battery
(12), an ultrasonic drive circuit (14), a sonic component (16) such as a motor, and a control …

Ultrasound (US) enhanced with microbubble contrast agents may transiently disrupt the
blood–brain barrier (BBB) with minimal damage, providing a technique for noninvasive …

Brain diseases are notoriously difficult to treat due to the presence of the blood-brain barrier
(BBB). Here, we review the development of focused ultrasound (FUS) as a noninvasive …
