Beschreibung
Zusammenfassung:	A high intensity focused ultrasound (HIFU) transducer comprising a piezoelectric array with a layer of piezoelectric material having a patient-facing front surface and a back surface, the front surface comprising a transmitting surface, and a plurality of electrodes located on the front and back surfaces of the piezoelectric material for applying electrical signals to the piezoelectric array. Electrical connections between an electrode on the back surface to an electrode on the front surface of the piezoelectric array are made through non-magnetic conductive vias extending through the layer of piezoelectric material.
