Claim 4:
5. An ultrasound therapeutic system comprising:
an ultrasonic delivery device having at least one ultrasonic element; and
a control system configured to generate a plurality of power parameters that drive the at least one ultrasonic element to generate ultrasonic energy waves, the control system including control circuitry comprising a hard-wired voltage source;
wherein the control system is configured to implement a non-linear protocol in a control routine to vary non-linearly at least one of selected power parameters of the plurality of power parameters and a physiological parameter;
wherein the a plurality of power parameters are selected from the group consisting of peak power, pulse repetition frequency (PRF), pulse width, duty cycle peak rarefactional pressure, spatial peak pulse average intensity, spatial peak time average intensity, or any combination thereof, and the physiological parameter comprises at least one of mechanical index and soft tissue thermal index, or any combination thereof;
wherein when the PRF is not the power parameter selected to be varied non-linearly, the PRF is selected to be varied linearly.
