Collapse Dynamics of Ultrasound Contrast Agent
Ultrasound contrast agents (UCAs) are micron-sized gas bubbles encapsulated with thin shells on the order of nanometers thick. The damping effects of these viscoelastic coatings are widely known to significantly alter the bubble dynamics for linear and low-amplitude behavior; however, their effects on strongly nonlinear and destruction responses are much less studied. This dissertation examines...

متن کاملEffects of ultrasound and ultrasound contrast agent on vascular tissue
BACKGROUND Ultrasound (US) imaging can be enhanced using gas-filled microbubble contrast agents. Strong echo signals are induced at the tissue-gas interface following microbubble collapse. Applications include assessment of ventricular function and virtual histology. AIM While ultrasound and US contrast agents are widely used, their impact on the physiological response of vascular tissue to v...
متن کاملTotal and Partial Liquid Ventilation Using Perfluorocarbons
Introduction The possibilities of using liquid instead of air in the exchange of gases have always fascinated researchers. The first studied liquid was saline solution which appeared to be unsuitable for transporting gases in normobaria. Its capacity to dissolve oxygen is low, and its viscosity and density are high as compared with air. Moreover, the introduction of saline into the lung can rem...
