Experimental study of localized heating of a biological tissue phantom by high-power phase conjugate ultrasonic beams

Experimental results on heating a biological tissue phantom using phase conjugate ultrasonic beams are presented. A polymer with acoustic properties close to those of biological tissues is used as the phantom. Heating is measured by thermocouples. The advantages of the proposed method of heating via wave phase conjugation include self-targeting of an ultrasonic beam on the region of heating and the weak effect the sample’s position or movement has on the heating parameters within a certain region.
