BYPASSING OBSTACLES IN FOCUSED ACOUSTIC WAVES

摘要

A method for irradiation includes defining a target (34) to be irradiated by acoustic energy from an acoustic emitter (24). An obstacle zone (36) is identified in a path of acoustic waves (32) between the acoustic emitter and the target. An excitation waveform to be applied to the acoustic emitter is computed so as to cause the acoustic energy emitted by the acoustic emitter to focus on the target while bypassing the obstacle zone.
