Abstract

Micro-bubbles are used as contrast agents in the field of medical ultrasound. When bubbles in liquid are driven by an acoustic wave, they repeatedly expand and contract. As the sound pressure increases, the bubbles vibrate nonlinearly and finally collapse with generation of a shock wave. The shock wave induces a high-pressure sound around the bubble. Therefore, in the practical usage of micro-bubbles in the human body, it is important to investigate the shock wave effects.
