Abstract

A system and method of tracking a flexible elongate instrument within a patient is disclosed herein. The system is configured to obtain remote localization measurement data of the flexible elongate instrument and obtain elongation measurement data of the flexible elongate instrument. This data is combined and transformed to a coordinate reference frame to produce a localization of the flexible elongate instrument that is more accurate than the remote localization measurements or elongation measurement data alone. The combined localization is then provided to a localization consumer.
