In a method for driving an injection device for injecting ultrasound into a tissue, the ultrasound has a predetermined thermal effect and a predetermined mechanical effect in the tissue. Ultrasound pulses are successively injected utilizing the injection device. Each ultrasound pulse comprises a pulse width and a duty ratio of the ultrasound pulses is set as a function of the thermal and mechanical effects of the ultrasound pulses. |
