Abstract
The present invention relates to an ultrasonic probe for heating, internally, an ultrasonically absorbent target medium, the probe comprising: at least one piezoelectric transducer (21) having a front face (212) intended to be positioned facing the target medium and a back face (211) opposite the front face (212), the transducer being able to emit at least one primary wave emanating from its front face and at least one secondary wave emanating from its back face, the probe being noteworthy in that it furthermore comprises: a reflector (24) facing the back face (211) of the transducer (21), the reflector (24) being suitable for reflecting the secondary wave emitted by the transducer (21); and a cooling-fluid layer (25) between the transducer (21) and the reflector (24).
