Fundamental limits and simulations on time difference of arrival source localization using ultrasound signals

Abstract

A catheter-mounted transducer transmits a signal that is received by a widely-spaced array of single element transducers. The signal time or time difference of arrival values at the transducers estimate the catheter position. System signal and noise characteristics dictate the lower bound jitter values for time delay estimates. Transducer placement in… (More)
