    Abstract: A method of tracking a medical instrument comprises receiving a model of an anatomical passageway formation and receiving a set of ordered sensor records for the medical instrument. The set of ordered sensor records provide a path history of the medical instrument. The method further comprises registering the medical instrument with the model of the anatomical passageway formation based on the path history. The method further includes displaying a virtual visualization image in a display system, the virtual visualization image being based on the registering of the medical instrument with the model of the anatomical passageway and depicting a rendered view of the model of the anatomical passageway from a perspective of the medical instrument within the model of the anatomical passageway.

    Abstract: A shape sensing apparatus comprises an instrument including an elongated shaft with a neutral axis. The shape sensor also includes a first shape sensor with an elongated optical fiber extending within the elongated shaft at a first radial distance from the neutral axis. The apparatus also includes a shape sensor compensation device extending within the elongated shaft and including a temperature sensor. The apparatus also comprises a tracking system for receiving shape data from the first shape sensor and compensating data from the shape sensor compensation device for use in calculating a bend measurement for the instrument.
