1. An image-guided prosthetic valve deployment system, comprising:

  • a prosthetic valve;

    a catheter having an elongated body with a proximal tip and a distal tip, the elongated body including a delivery section adjacent the distal tip for deploying the prosthetic valve relative to a heart valve within an anatomical region,wherein the delivery section includes a delivery segment operable for sensing a shape and an orientation of the delivery section within the anatomical region relative to a reference element located at a position along the delivery section, andwherein the delivery segment includes;

    an optical fiber including a deformation sensor optic array operable for sensing the shape and the orientation of the delivery section within the anatomical region relative to the reference element; and

    an electromagnetic coil for defining the reference element;

    a delivery tracking system in communication with the delivery segment to track a position and an orientation of the prosthetic valve relative to the heart valve as a function of a sensed shape and a sensed orientation of the delivery section within the anatomical region relative to the reference element as sensed by the delivery segment; and

    an image guiding system in communication with the delivery tracking system to display an orientation of the prosthetic valve relative to a valve annulus plane of the heart valve derived from at least one of the sensed shape and the sensed orientation of the delivery section within the anatomical region relative to the reference element,wherein the valve annulus plane is extracted from within a volume image of the anatomical region excluding the prosthetic valve.
