System and method of intraluminal navigation using a 3D model
First Claim
1. A system for lung navigation comprising:
- a tracking system receiving signals from a probe;
a workstation in operable communication with the tracking system; and
a user interface in operable communication with the workstation, wherein the user interface is configured to display;
a three-dimensional (3D) lung model generated from a plurality of computer tomography (CT) images;
a planned pathway to a target on the 3D lung model;
an image of at least a portion of a digital probe in the 3D lung model, wherein a displayed position of the image of the at least a portion of the digital probe in the 3D model corresponds to signals from the probe; and
the 3D model with an object that is hidden or ghosted out.

Abstract
A method for implementing a dynamic three-dimensional lung map view for navigating a probe inside a patient'"'"'s lungs includes loading a navigation plan into a navigation system, the navigation plan including a planned pathway shown in a 3D model generated from a plurality of CT images, inserting the probe into a patient'"'"'s airways, registering a sensed location of the probe with the planned pathway, selecting a target in the navigation plan, presenting a view of the 3D model showing the planned pathway and indicating the sensed location of the probe, navigating the probe through the airways of the patient'"'"'s lungs toward the target, iteratively adjusting the presented view of the 3D model showing the planned pathway based on the sensed location of the probe, and updating the presented view by removing at least a part of an object forming part of the 3D model.

8. A method of updating a lung navigation user interface, comprising:
-
displaying a planned pathway to a target on a three-dimensional (3D) lung model generated from a plurality of computer tomography (CT) images on the user interface; displaying at least a portion of a digital probe in the 3D lung model, wherein a displayed position of the digital probe in the 3D lung model corresponds to a determined position of a catheter; and updating the user interface upon detection of a change in location of the catheter to update the displayed position of the digital probe in the 3D lung model and to alter a transparency of at least a first portion of the 3D lung model and remove at least a second portion of the 3D lung model in response to detected change in location of the catheter. - View Dependent Claims (9, 10, 11, 12, 13, 14)
