1. A system for accessing a target location within a luminal network, the system comprising:
- a locatable guide insertable through a luminal network from an entry point to a target location;
a non-transitory computer readable medium storing a program for causing a computer to determine a pathway through the luminal network from the entry point to the target location and assign a plurality of waypoints along the pathway; and
a user interface configured to display an orientation of the locatable guide relative to a next one of the plurality of waypoints as the locatable guide is inserted through the luminal network from the entry point towards the target location.

Abstract
A navigation system for use in a luminal network of a patient, such as the airways, that is able to analyze a three-dimensional model of the luminal network and automatically determine a pathway from an entry point to a designated target. The system further automatically assigns waypoints along the determined pathway in order to assist a physician in navigating a probe to the designated target.

14. A system for accessing a target location within a luminal network, the system comprising:
-
a locatable guide insertable through a luminal network from an entry point to a target location; a non-transitory computer readable medium storing a program for causing a computer to determine a pathway through the luminal network from the entry point to the target location; and a user interface operable in both a planning mode, wherein a simulated navigation view from the entry point to the target location is displayed, and a navigation mode, wherein an orientation of the locatable guide within the luminal network and relative to the pathway as the locatable guide is inserted through the luminal network from the entry point towards the target location is displayed. - View Dependent Claims (15, 16, 17, 18, 19, 20)
