Ultrasonic therapeutic device for outputting an ultrasonic wave having a cavitation effect and thermal effects

摘要

An ultrasonic therapy apparatus including at least one treatment device (12) with at least one piezoelectric transducer element (14) for at least performing said therapy in order to destroy a target (16) such as tissue, and a controller (22) for controlling said device (12). The controllers (20, 22) for controlling said device (12) cause the treatment device (12) to deliver two kinds of ultrasonic waves, namely a first or thermal kind having a predominantly thermal effect on the tissue (16) to be treated, and a second or cavitational kind having a predominantly cavitational effect thereon. Internal or external benign or malignant tumours in the body of a mammal (M) may thereby be ultrasonically treated.
