METHOD AND SYSTEM FOR ADAPTIVE IMAGE GUIDED INTERVENTION
First Claim
1. A method for generating imaging data during a medical intervention performed on a patient, the method comprising:
- attaching an external optical sensor on the patient'"'"'s body, the external optical sensor comprising at least one external orientation fiber core configured to deform due to insertion of a medical intervention instrument during the medical intervention and configured to measure an orientation of the external optical sensor relative to a point of reference;
optically interrogating the external optical sensor to generate external sensor orientation information regarding the external optical sensor during the medical intervention, and using the external sensor orientation information to estimate the orientation of the external optical sensor during the medical intervention; and
displaying deformation of the patient'"'"'s body due to insertion of the medical intervention instrument using, at least in part, the external sensor orientation estimate.

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.
