Claim 12:
13. A method of registering to images of a patient's at least one body part, comprising:
recording a shape of a segment of the patient's at least one body part based on location data from a sensor, yielding a recorded shape;
generating a three-dimensional (3D) model from 3D images of the patient's at least one body part;
determining a segment in the 3D model that corresponds to the recorded shape;
comparing previously acquired images of the patient's at least one body part to virtual images derived from the 3D images to identify a subgroup of the 3D images of the patient's at least one body part;
registering a location of the sensor relative to the subgroup of the 3D images of the patient's at least one body part based on the location data, yielding a registered location; and
updating the registered location of the sensor based on one or more images selected from the subgroup of the 3D images of the patient's at least one body part.
