Disclosed is a method of treatment of soft tissue where at least two ultrasound transducers are applied to a tissue protrusion and operated to emit the protrusion ultrasound radiation in pulse or continuous operation mode. At least one of the transducers receives a portion of the ultrasound power emitted by the other transducer and transmitted through the protrusion. A controller analyzes the received portion of the ultrasound and employs the data for actively monitoring the ultrasound radiation with tissue coupling. Disclosed is also an apparatus enabling implementation of the method.
