Pathway planning system and method
First Claim
1. A system for planning a pathway through an anatomical luminal network of a patient, the system comprising:
- a computing device including at least one processor;
a display device in communication with the computing device; and
a user interface configured for display on the display device and configured to guide a user through a pathway planning procedure, the user interface comprising;
a patient selection window configured to receive a user input to select a patient having computed tomographic (CT) image data on which to perform pathway planning;
a target selection window configured to receive a user input to select at least one target from the CT image data; and
an airway finder window configured to generate at least one pathway from the at least one target to an entry point of the anatomical luminal network in response to a user input, wherein the airway finder window is further configured to display a CT image including the selected at least one target, the CT image being initially rotatable about an axis extending from the at least one target to a trachea and upon selection by a user of a first suspected airway redefines the axis of rotation to extend between the target and the first suspected airway.

Abstract
A system and method for planning a pathway through an anatomical luminal network of a patient including a computing device having at least one processor; a display device in communication with the computing device; and a user interface configured for display on the display device and configured to guide a user through a pathway planning procedure. The user interface includes a patient selection window configured to receive a user input to select a patient having CT image data on which to perform pathway planning; a target selection window configured to receive a user input to select at least one target from the CT image data; and an airway finder window configured to generate at least one pathway from the at least one target to an entry point of the anatomical luminal network in response to a user input.

9. A method for planning a pathway through an anatomical luminal network of a patient, the method comprising the steps of:
-
importing computed tomographic (CT) image data of a patient selected by a user input; generating a three-dimensional CT volume from the CT image data; displaying a slice of the three-dimensional CT volume; receiving a user input identifying at least one target; defining initially an axis of rotation extending from the identified at least one target to a trachea of the three-dimensional CT volume, wherein the axis of rotation, upon selection by the user of a first suspected airway, is redefined to extend between the target and the first suspected airway; rotating the slice of the three-dimensional CT volume about the axis of rotation; receiving an input from a user indicating a location for a new waypoint in an airway of the rotated slice; setting a first waypoint in the indicated location in the airway; and generating a first pathway from the at least one target to the first waypoint. - View Dependent Claims (10, 11)

12. A non-transitory computer-readable storage medium encoded with a program that, when executed by a processor causes a user interface to perform the steps of:
-
importing computed tomographic (CT) image data of a patient selected by a user input; generating a three-dimensional CT volume from the CT image data; displaying a slice of the three-dimensional CT volume; receiving a user input identifying at least one target; defining initially an axis of rotation extending from the identified at least one target to a trachea of the three-dimensional CT volume, wherein the axis of rotation, upon selection by the user of a first suspected airway, is redefined to extend between the target and the first suspected airway; rotating the slice of the three-dimensional CT volume about the axis of rotation; receiving an input from a user indicating a location for a new waypoint in an airway of the rotated slice; setting a first waypoint in the indicated location in the airway; and generating a first pathway from the at least one target to the first waypoint. - View Dependent Claims (13, 14)
