Three-dimensional digital ultrasound tracking system

Abstract

A method and apparatus for simultaneous measurement of multiple distances by means of networked piezoelectric transducers. Through the use of high frequency digital counters, the propagation delay between the activation of an ultrasonic transducer and the reception by similar transducers is quickly and accurately defined. By alternating the duty cycle between transmit and receive modes, the system can track and triangulate the three-dimensional positions for each transducer.
