1. A system for planning a pathway through an anatomical luminal network of a patient, the system comprising:
- memory storing a computer program configured to analyze and manipulate CT images;
a processor configured to execute the computer program; and
a display device configured to display a user interface of the computer program, the user interface comprising;
an airway finder window displaying a volumetric view of the anatomical luminal network including a target, the volumetric view rotatable about a pre-defined axis of rotation to assist a user in identifying an airway of the anatomical luminal network in proximity to the target, wherein the pre-defined axis of rotation extends outside of the airway of the anatomical luminal network and as the volumetric view of the anatomical luminal network is rotated about the pre-defined axis a simulated CT image of the anatomical luminal network depicting a slice of the volumetric view along the pre-defined axis of rotation is displayed.

Abstract
A system and method for planning a pathway through an anatomical luminal network of a patient including memory storing a computer program that is configured to analyze and manipulate CT images, a processor configured to execute the computer program and a display device configured to display a user interface of the computer program. The user interface includes an airway finder window displaying a CT image including a target. The CT image is rotatable about a pre-defined axis of rotation to assist a user in identifying an airway of the anatomical luminal network.

11. A method for planning a pathway through an anatomical luminal network of a patient, the method comprising the steps of:
-
defining an axis of rotation, from a target to a known airway of the anatomical luminal network, wherein the axis of rotation extends outside of an airway of the anatomical luminal network; rotating a CT image about the axis of rotation such that a non-displayed airway of the anatomical network becomes a displayed airway of the anatomical network; receiving an input from a user indicating a location for a new waypoint in an airway of the rotated CT image based on the displayed airway of the anatomical network; and generating a new pathway from the target to the new waypoint. - View Dependent Claims (12, 13, 14, 15)
