Microbubbles can grow from nuclei and collapse violently under acoustic pressure. This phenomenon is called acoustic cavitation. The gas in the microbubbles is adiabatically compressed in the violent collapse, and its temperature can reach thousands of degrees. This is regarded as the primary mechanism of sonoluminescence and sonochemical reactions. Research undergoing on the use of acoustic cavitation for inducing therapeutic effects with ultrasound is described in this paper.
