Abstract
A method and apparatus for performing therapy using ultrasound. The apparatus uses a treatment device having at least one piezoelectric transducer element to supply ultrasonic waves focussed onto a focal point or region that determines the tissue zone submitted to therapy. The treatment device, which is controlled by a control device, supplies two types of ultrasonic waves, the first one being thermal waves that produce a predominantly thermal effect on the tissue being treated and the second one being cavitation waves that produce a predominantly cavitation effect on the tissue to be treated.
