1. A method for generating high power the therapeutic ultrasound waves in a propagation medium, said ultrasound waves produced by an ultrasonic transducer having at least one ultrasound transducer element, the method comprising the steps of:

  • activating the at least one ultrasound transducer element with an electronic signal supplied by a signal generator;

    said signal generator supplying a wideband electronic signal to said at least one ultrasound transducer element for reducing or preventing cavitation phenomena resulting from the propagation of the ultrasound waves emitted by the at least one ultrasound transducer element within the propagation medium; and

    said wideband electronic signal being a Golay coded pseudo-random type signal.
