摘要：
A method and system for secure ultrasound treatment of living tissues using an ultrasound probe (2) comprising a reflective cavity (9) in acoustic communication with living tissues (L), a transducer (6) to emit an ultrasound wave in the reflective cavity (9) and a transducer (6) to acquire a backscattered signal in the reflective cavity (9).The method comprises the steps ofa) emitting a first ultrasound wave in the reflective cavity (9) that generates a backscattered ultrasound wave in the reflective cavity (9),b) acquiring a backscattered signal in the reflective cavity,c) determining whether an insonification can be safely performed by computing a similarity value between the backscattered signal and a predefined reference signal, andd) if an insonification can be safely performed, treating the living tissues with a second ultrasound wave emitted in the reflective cavity (9). The second ultrasound wave is focused a target point of the living tissues and generates a pressure pulse sufficient to result in cavitation at this target point
