Abstract
A shape sensing device, system and method include an interventional instrument (102) having regions of articulation to be configured to change shape during an interventional procedure. An optical fiber (202) is disposed on or about the areas of articulation in a pattern to provide an optical signal indicating an instantaneous change or current position or orientation of the instrument. A signal interpretation module (115) is configured to receive the optical signals and interpret the instantaneous change or current position or orientation of the instrument.
