1. A method for implementing a dynamic three-dimensional (3D) lung map view for navigating a probe inside a patient's airways, the method comprising: loading a navigation plan into a navigation system, the navigation plan including a planned pathway shown in a 3D model generated from a plurality of CT images; presenting guidance for inserting a probe into a patient's airways, the probe including a location sensor in operative communication with the navigation system; presenting a view of the 3D model showing the planned pathway and indicating a sensed location of the probe; presenting guidance for navigating the probe through the patient's airways; iteratively adjusting the presented view of the 3D model showing the planned pathway based on the sensed location of the probe; and updating the presented view of the 3D model by removing at least a part of an object forming part of the 3D model.
