An ultrasound catheter system and a method for operating an ultrasonic catheter at a treatment site within a patient's vasculature or tissue are disclosed. The ultrasound catheter system comprises a catheter having at least one ultrasonic element and a control system configured to generate power parameters that drive the at least one ultrasonic element to generate ultrasonic energy. The control system is configured to vary at least one of the power parameters and at least one physiological parameter by ramping the power parameter and the physiological parameter between two set of minimum and maximum values.
