11. A method for endoscopic path planning, comprising:
-
manually selecting a target in a lung, wherein the target is located in or near a peripheral airway of the lung;
manually selecting a location inside an artery leading to the target, and a location inside an airway leading to the target, wherein the two locations form a jump point;
automatically determining which of the two locations corresponds to the inside of the artery and the inside of the airway;
manually selecting a target point within an artery that is near the target;
automatically generating a retrograde angioscopic path from the target point to the jump point; and
automatically generating a retrograde bronchoscopic path from the jump point to a trachea. - View Dependent Claims (12, 13, 14)

15. A method for endoscopic path planning, comprising:
-
manually selecting a target in a lung;
manually selecting a location inside an artery leading to the target, and a location inside an airway parallel to the selected artery, wherein the two locations form a jump point;
manually selecting a point within an artery that is near the target;
manually generating a retrograde angioscopic path from the artery near the target to the jump point; and
manually generating a retrograde bronchoscopic path from the jump point to a trachea. - View Dependent Claims (16)

17. A method for performing a bronchoscopy using a planned endoscopic path, comprising:
-
inserting a bronchoscope into a lung;
acquiring a first image, wherein the first image includes a location of a tip of the bronchoscope in the lung;
registering the first image with a corresponding image from the planned endoscopic path; and
determining where the tip of the bronchoscope is located in relation to where it is located in the planned endoscopic path. - View Dependent Claims (18)

19. A system for endoscopic path planning, comprising:
-
a memory device for storing a program;
a processor in communication with the memory device, the processor operative with the program to;
identify a target in a lung, wherein the target is located in or near a peripheral airway of the lung; and
generate an endoscopic path to the target, wherein a peripheral artery is used as a surrogate for the peripheral airway. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

31. A method for method for automatically deriving computer-generated virtual endoscopic pathways leading from airways to peripheral nodules using arteries as substitute markers for the location of peripheral airways when the peripheral airways are not detectable by computed tomographic (CT) scans, comprising:
-
identifying a nodule in a lung, wherein the nodule is located in or near one of the peripheral airways;
generating a virtual endoscopic path to the nodule, wherein one of the peripheral arteries is used as a substitute for one of the peripheral airways leading to the nodule, the step of generating the virtual endoscopic path comprises;
segmenting data associated with the lung, wherein airways and arteries of the lung are segmented;
computing an airway tree of the segmented airways and an artery tree of the segmented arteries;
matching the computed airway and artery trees;
determining the virtual endoscopic path to the target; and
selecting a jump location where the virtual endoscopic path switches to the peripheral artery which is the substitute for one of the peripheral airways; and
viewing the virtual endoscopic path.
