A method for locating a catheter transducer in a 3-D ultrasound field

摘要

This paper presents a method for using ultrasound to locate a catheter mounted transducer in three dimensions. The method processes signals received on the catheter transducer to locate its position within the emitted ultrasonic field. Thesimulation results indicate the position of the catheter tip can be determined with an average angular error of 0.12° for a signal-to-noise ratio of 20dB.
