Claim 15:
16. A system for navigating to a target, the system comprising:
a catheter navigable within a patient's airways, the catheter including a location sensor for detecting a location of the catheter within the patient's airways; and
a computing device operably coupled to the catheter, the computing device configured to:
generate a 3D view using image data of the patient's airways by executing a first transfer function for a first range from the location sensor to identify one or more airways within the image data and executing a second transfer function for a second range from the location sensor to identify one or more targets within the image data, the second transfer function configured to distinguish between a density of the one or more targets and a density of structures other than the one or more targets,
wherein the second transfer function causes the generated 3D view to omit structures other than the one or more targets located beyond the range of the first transfer function to avoid obscuring the view of the one or more targets within the image data based upon the differing densities between the one or more targets and the structures other than the one or more targets.
