ABSTRACT:
A method and apparatus are disclosed for coupling ultrasound between an ultrasonic transducer and an object. A fluid cavity in an upper chamber has an inlet for receiving a flow of coupling fluid, a first aperture for admitting the ultrasonic transducer into the fluid cavity and a second aperture for dispensing coupling fluid from the fluid cavity to the object. The first and second apertures may be sized to restrict flow of coupling fluid from the fluid cavity. The focus of the ultrasound transducer may be varied by moving the ultrasonic transducer relative to the upper chamber.
