Abstract
A method and apparatus are disclosed for coupling ultrasound between an ultrasonic transducer and an object. A scanning element is attached to an ultrasonic transducer to form an integral transducer assembly in which an ultrasound emitting surface of the ultrasonic transducer is positioned in a fluid cavity of an upper chamber. The ultrasonic transducer assembly may be moved relative to the object to be scanned in order to adjust the focus of the ultrasound. Adjusting a lower wall of the upper chamber in close proximity to the object to be scanned forms a thin film of coupling fluid between a planar region of the lower wall and the upper surface of the object.
