Vanderbilt University, Richard V Eckert Seamans Cherin & Mellott Westerhoff, August 22, 2000: US06106464 (94 worldwide citation)

An A-mode ultrasound transducer is tracked in three-dimensions by an optical position tracking system as the transducer is scanned over the skin to generate measurements of bone surface distance from the transducer. A processor correlates the ultrasound data with position and orientation data to gen ...
