Pathway planning for use with a navigation planning and procedure system

A navigation planning and procedure system comprising:

• a display device;
• at least one processor in communication with the display;
• and
• a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to:
• generate a three-dimensional (3D) model of a luminal network;
• cause the display device to display the 3D model of the luminal network;
• select a target location in tissue adjacent to and outside of the luminal network as displayed on the 3D model;
• identify a point in the luminal network which is proximate to the target location;
• determine an access path between the target location and the identified point in the luminal network;
• calculate a risk of injury to intervening structures between the target location the point in the luminal network which is proximate to the target location, based on the determined access path;
• and
• cause the display device to display the access path and the calculated risk of injury for the access path on the 3D model.

A non-transitory computer-readable storage medium storing instructions which, when executed by a processor, cause a computer to:

• generate a three-dimensional (3) model of a luminal network;
• cause a display device to display the 3D model of the luminal network;
• select a target location in tissue adjacent to and outside of the luminal network as displayed on the 3D model;
• identify a point in the luminal network which is proximate to the target location;
• determine an access path between the target location and the identified point in the luminal network;
• calculate a risk of injury to intervening structures between the target location and the identified point in the luminal network, based on the determined access path;
• and
• cause a display device to display the access path and the calculated risk of injury for the access path on the 3D model.
