    Abstract: A method of operating a shape sensing apparatus is provided. The method comprises receiving shape data from an elongated shape sensor having a first portion coupled to a reference fixture, a second portion coupled to an anatomic target, and a third portion coupled to the reference fixture. The first and third portions are maintained in a known kinematic relationship. The method further comprises determining a first shape of the elongated shape sensor between the first and second portions. The method further comprises determining a second shape of the elongated shape sensor between the third and second portions. The method further comprises determining a position of the second portion at the anatomic target from the first and second shapes.

    Abstract: A medical system includes an elongate instrument, a tracking system, and one or more processors. The tracking system is disposed along at least a portion of the elongate instrument. The one or more processors are coupled to the tracking system and are configured to: generate a plurality of linked bounded-surface elements corresponding to a set of connected passageways of a patient anatomy; receive shape information from the tracking system, the shape information indicating a shape of at least a portion of the elongate instrument when the portion is disposed in the set of connected passageways; register the shape information to the plurality of linked bounded-surface elements; and based on the registering, display a composite image including an instrument image of the elongate instrument displayed within a model of the set of connected passageways.
