Abstract
A method performed by a computing system comprises receiving a collected set of spatial information for a distal portion of an instrument at a plurality of locations within a set of anatomic passageways and receiving a set of position information for a reference portion of the instrument when the distal portion of the instrument is at each of the plurality of locations. The method also comprises determining a reference set of spatial information for the distal portion of the instrument based on the collected set of spatial information and the set of position information for the reference portion of the instrument and registering the reference set of spatial information with a set of anatomical model information.
