Abstract
Diagnostic ultrasound is used to measure distance from a transducer to selected tissue structure. In one arrangement, the focal point of a high intensity focused ultrasound transducer is adjusted in accordance with measured distance to the selected tissue structure. In a second arrangement a transducer transport apparatus moves a transducer to maintain a selected distance from tissue structure.
