ABSTRACT:
A hyperthermia applicator comprises a generator of a focused ultrasonic beam comprising a main high frequency electric wave emitter and a main piezoelectric transducer and an echography device comprising an auxiliary high frequency electric pulse generator associated with an auxiliary piezoelectric transducer which generates an ultrasonic examination beam sweeping the zone to be treated. During a main treatment and checking operating mode, the focused beam is emitted by the main transducer energized by the main emitter during periodic time intervals separated by shorter time intervals. During the shorter time intervals, the examination beam is emitted and echographic images are formed.
