Methods and Systems for Controlling and Acoustic Energy Deposition in Various Media

摘要

A system and method for controlling acoustic energy deposition in various media or objects are disclosed. The system and method can generate an acousto-mechanical or acousto-elastic effect in the various media or objects. The acousto-mechanical or acousto-elastic effect can induce a fragmentation of the media or objects.

1. A method of inducing an acousto-mechanical or acousto-elastic effect in a target zone of a medium, the method comprising:
a) coupling an ultrasound energy source to the target zone of the medium, the ultrasound energy source configured to produce a pulsed first ultrasound energy having a frequency of between 100 kHz and 200 MHz and a pulse duration of between 100 picosecond and 1 millisecond; b) directing from 500 nJ to 5 J of the pulsed first ultrasound energy from the ultrasound energy source into the target zone of the medium, thereby initiating an acousto-mechanical or acousto-elastic effect in the target zone.
