Abstract

An ultrasonic processing apparatus is provided. The ultrasonic processing apparatus comprises an ultrasonic therapy transducer (ATA) adapted to generate focused ultrasonic waves; an ultrasonic imaging transducer (UID) connected to the ultrasonic therapy transducer; and an electronic system configured to control the ultrasonic therapy transducer so as to emit a pulse train of ultrasonic waves generating a cloud of cavitation bubbles (BC); control the ultrasonic imaging transducer so as to acquire at least one image of the region to be processed; acquire a plurality of echo signals of ultrasonic wave pulses emitted by the ultrasonic therapy transducer captured by the ultrasonic imaging transducer; process the plurality of echo signals so as to reconstruct an image of the cloud of cavitation bubbles; and display said image of the cloud of cavitation bubbles superposed on said image of the region to be processed. The processing includes spatio-temporal filtering.
