    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.

    Abstract: A method includes collecting a set of measured points with a flexible catheter as the flexible catheter is inserted into one or more anatomic passageways of a patient in which the measured points are based on a position of the flexible catheter in a patient space, assigning each measured point of the set of measured points to a respective subset of a plurality of subsets of measured points based upon a depth of each measured point within the one or more anatomic passageways, comparing the plurality of subsets to identify an optimal subset of the plurality of subsets, and registering a model of the one or more anatomic passageways to the patient space based on a set of model points of the model and the optimal subset.
