THERMAL THERAPY APPARATUS AND METHOD USING FOCUSED ULTRASONIC SOUND FIELDS

摘要

Apparatus and method for delivering increased amounts of energy to localized treatment zones in a target tissue volume are provided. In some instances the non¬ linear wave propagation and other properties of the treatment apparatus and propagation medium as well as novel beam forming and control of the treatment apparatus are employed to generate extended focal zones for efficient treatment of a condition in a patient.
