Claim 2:
3. A control system for an ultrasound catheter comprising control circuitry the control system configured to implement a non-linear protocol in a control routine to non-linearly vary a power parameter and a physiological parameter created by an ultrasonic element of an ultrasonic catheter connected to an energy source, wherein the control circuitry comprises a hard-wired voltage source, wherein the power parameter is selected from the group consisting of peak power, pulse repetition frequency (PRF), pulse width, and duty cycle and the physiological parameter comprises at least one of mechanical index and soft tissue thermal index, wherein when the PRF is not the power parameter selected to be varied non-linearly, the PRF is selected to be varied linearly.
