Effects of varying ultrasound parameters on the oscillation of a microbubble near a boundary

Microbubbles are currently used as ultrasound contrast agents. However, microbubbles have the potential to be used in diagnostic imaging and therapeutic applications. Most numerical work on simulating microbubble oscillation involves modelling microbubbles in infinite medium whereas clinical trials...
