Abstract

Methods and systems for navigating to a target through a patient's bronchial tree are disclosed including a bronchoscope, a probe insertable into a working channel of the bronchoscope including a location sensor, and a workstation in operative communication with the probe and the bronchoscope the workstation including a user interface that guides a user through a navigation plan and is configured to present a three-dimensional (3D) view for displaying a 3D rendering of the patient's airways and a corresponding navigation plan, a local view for assisting the user in navigating the probe through peripheral airways of the patient's bronchial tree to the target, and a target alignment view for assisting the user in aligning a distal tip of the probe with the target.

First claim

What is claimed is:

1 . A system for navigating to a target through a patient's bronchial tree, the system comprising:
a bronchoscope configured for insertion into the patient's bronchial tree, the bronchoscope defining a working channel; a probe insertable into the working channel of the bronchoscope and configured to navigate through the patient's bronchial tree, the probe including a location sensor; and a workstation in operative communication with the probe and the bronchoscope, the workstation including a memory and at least one processor, the memory storing a navigation plan and a program that, when executed by the processor, presents a user interface that guides a user through the navigation plan, the user interface configured to present:
a three-dimensional (3D) view for displaying a 3D rendering of the patient's airways and a corresponding navigation plan;
a local view for assisting the user in navigating the probe through peripheral airways of the patient's bronchial tree to the target; and
a target alignment view for assisting the user in aligning a distal tip of the probe with the target.

2 . The system according to claim 1 , wherein the processor executes a maximum intensity projection (MIP) algorithm for a range from a distal tip of the location sensor.

3 . The system according to claim 2 , wherein the range is predetermined.

4 . The system according to claim 2 , wherein the range is dynamically calculated based on a location of the target.

5 . The system according to claim 2 , wherein the MIP algorithm causes the target to be displayed in a maximal surface size in the target alignment view.

6 . The system according to claim 2 , wherein the MIP algorithm highlights the target and filters out densities of other tissue near the target.

7 . The system according to claim 1 , wherein the target alignment view presents a marking overlaid on the target.

8 . The system according to claim 1 , wherein the target alignment view presents a crosshair to assist alignment to a center of the target.

9 . The system according to claim 1 , wherein the target alignment view presents a distance from a tip of the location sensor to the target.

10 . A system for navigating to a target through a patient's bronchial tree, the system comprising:
a bronchoscope configured for insertion into the patient's bronchial tree, the bronchoscope defining a working channel; a probe insertable into the working channel of the bronchoscope and configured to navigate through the patient's bronchial tree, the probe including a location sensor; and a workstation in operative communication with the probe and the bronchoscope, the workstation including a memory and at least one processor, the memory storing a navigation plan and a program that, when executed by the processor, presents a user interface that guides a user through the navigation plan, the user interface configured to present a target alignment view for assisting the user in aligning a distal tip of the probe with the target, wherein the processor executes a maximum intensity projection (MIP) algorithm for a limited range from a distal tip of the location sensor.

11 . The system according to claim 10 , wherein the limited range is predetermined.

12 . The system according to claim 10 , wherein the limited range is dynamically calculated based on a location of the target.

13 . The system according to claim 10 , wherein the MIP algorithm causes the target to be displayed in a maximal surface size in the target alignment view.

14 . The system according to claim 10 , wherein the MIP algorithm highlights the target and filters out densities of other tissue near the target.

15 . The system according to claim 10 , wherein the target alignment view presents a marking overlaid on the target.

16 . The system according to claim 10 , wherein the target alignment view presents a crosshair to assist alignment to a center of the target.

17 . The system according to claim 10 , wherein the target alignment view presents a distance from a tip of the location sensor to the target.
