Abstract

A method and system for generating imaging data during a medical intervention are provided. An external optical sensor is attached on the patient'"'"'s body, and includes at least one external orientation fiber core configured to measure an orientation of the external optical sensor relative to a point of reference. The external optical sensor is interrogated to generate external sensor orientation information during the medical intervention. That information is used to estimate an orientation of the external optical sensor, which is then displayed during the medical intervention.
