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 sensor, the sensor configured to generate location information and pose information; 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, causes the workstation to:
receive the location information and the pose information,
execute a maximum intensity projection (MIP) algorithm for a range from a distal tip of the sensor according to the location information and the pose information,
present 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 display of the 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
an alignment view for assisting the user in aligning a distal tip of the probe with the target, the alignment view including an image generated from the execution of the MIP algorithm.

2. The system according to claim 1 , wherein the range is predetermined.

3. The system according to claim 1 , wherein the range is dynamically calculated based on a location of the target.

4. The system according to claim 1 , wherein the MIP algorithm highlights the target and filters out densities of other tissue near the target.

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

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

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

8. 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 sensor, the sensor configured to generate location information and pose information; 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, causes the workstation to:
receive the location information and the pose information,
execute a maximum intensity projection (MIP) algorithm for a range from a distal tip of the sensor according to the location information and the pose information,
presents a user interface that guides a user through the navigation plan, the user interface configured to present an alignment view for assisting the user in aligning a distal tip of the probe with the target,
wherein the range from the distal tip of the sensor is a limited range from the distal tip of the sensor.

9. The system according to claim 8 , wherein the limited range is predetermined.

10. The system according to claim 8 , wherein the limited range is dynamically calculated based on a location of the target.

11. The system according to claim 8 , wherein the MIP algorithm highlights the target and filters out densities of other tissue near the target.

12. The system according to claim 8 , wherein the alignment view presents a marking overlaid on the target.

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

14. The system according to claim 8 , wherein the alignment view presents a distance from a tip of the sensor to the target.
