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 کاملRed Blood Cells as an Ultrasound Contrast Agent
Microbubbles, shell-stabilized micrometersized gas bubbles, are the most common ultrasound contrast agent. Microbubbles can both improve ultrasound image contrast as well as enhance drug delivery. Current microbubble formulations, however, have a limited halflife in vivo and a limited therapeutic carrying capacity. Red blood cells continue to be investigated as a drug delivery vehicle given the...
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 کامل“Non-thermal” ablation using focused ultrasound and an ultrasound contrast agent
Background/introduction The combination of focused ultrasound and an intravenously-injected microbubble ultrasound contrast agent offers the ability to reduce the power needed to ablate tissue, which is particularly important for targets in the brain since it can eliminate skull heating. When applied at a low duty cycle so that bulk tissue heating does not occur, the mechanical effects induced ...
