Abstract

Methods and systems for displaying a volumetric model of a patient'"'"'s lung including sublobar regions. The system may include a processor and software operable on the processor to receive data from multi-dimensional images of the patient'"'"'s lungs, such as CT images, and produce data for creation of a volumetric model of the patient'"'"'s lungs, including sublobar regions, on a graphical user interface. The system may also display the multi-dimensional images on the graphical user interface. A user may select an airway location in the airways on the volumetric model or a multi-dimensional image on the graphical user interface and the portion of the lung distal to the selected location, which may be a sublobe, may be highlighted and/or characterized by the system.

Claims

1. A system for providing a volumetric model of a patient'"'"'s lungs, the system comprising:

a processor;

software operable on the processor, wherein the software receives data from multi-dimensional images of the patient'"'"'s lungs and produces data for creation of a volumetric model of the patient'"'"'s lungs on a graphical user interface, wherein the volumetric model includes sublobar airways.

2. The system of claim 1 wherein the system allows a user to select a location on the volumetric model, and wherein the system can highlight a portion of the lung distal to the user selected location on the volumetric model, wherein the portion of the lung is a sublobe.

3. The system of claim 1 wherein the software is further operable to display a multi-dimensional image of the lungs on the graphical user interface.

4. The system of claim 1 wherein the software is further operable to display three orthogonal multi-dimensional images of the lungs on the graphical user interface.

5. The system of claim 4 wherein the system allows a user to select a location on one of the multi-dimensional images of the lungs, and wherein the system can highlight on the volumetric model a portion of the lung distal to the user selected location, wherein the portion of the lung is a sublobe.

6. The system of claim 5 wherein the system can further highlight on one or more of the multi-dimensional images the portion of the lung distal to the user selected location.

7. The system of claim 6 wherein the user may select a location on the model and the graphical user interface will highlight an associated region of the lung distal to the selected location in the model and in each of the multi-dimensional images.

8. The system of claim 7 wherein the system can further provide data on the graphical user interface regarding the highlighted region of the lung.

9. The system of claim 6 wherein the data comprises volume and/or density of the highlighted region of the lung.

10. The system of claim 4 wherein the system allows a user to select a location on the volumetric model or on one of the multi-dimensional images as a location of a proposed therapy.

11. The system of claim 10 wherein the proposed therapy is the placement of a one-way valve.

12. The system of claim 4 wherein the system allows a user to select a location on the volumetric model or on one of the multi-dimensional images as a bronchoscopy target.

13. A computer readable medium comprising machine readable instructions for:

receiving data corresponding to multi-dimensional images of a patient'"'"'s lungs;

generating a volumetric model of the patient'"'"'s airway; and

displaying the volumetric model on a graphical user interface, wherein the model includes sublobes of the patient'"'"'s lungs.

14. The computer readable medium of claim 13 wherein the computer readable-medium further comprises instructions for displaying multi-dimensional images of the patient'"'"'s lungs on the graphical user interface.

15. The computer readable medium of claim 14 wherein the computer readable-medium further comprises instructions for:

receiving user input identifying a location on the volumetric model or on a multi-dimensional image on the graphical user interface;

altering the volumetric model to highlight a portion of the airway tree, that portion being all of the airway distal to the user identified location; and

altering the multi-dimensional images to highlight the portion of the airway tree;

wherein the portion of the airway tree is a sublobe.

16. The computer readable medium of claim 15 wherein the computer readable medium further comprises instruction for calculating data corresponding the to the portion of the airway tree and displaying the data on the graphical user interface.

17. The computer readable medium of claim 16 wherein the data comprises volume and/or density.

18. A method of visualizing a sublobe of a patient comprising:

providing multi-dimensional imaging data of the patient'"'"'s lungs to a system, the system comprising;

a graphical user interface;

a processor; and

software operable on the processor, wherein the software receives the data from the multi-dimensional images of the patient'"'"'s lungs and produces data for creation of a volumetric model of the patient'"'"'s lungs on the graphical user interface, wherein the volumetric model includes sublobar airways.

19. The method of claim 18, further comprising:

selecting a location on the volumetric model, wherein the system is adapted to highlight a portion of the lung distal to the user selected location on the volumetric model, and wherein the highlighted portion of the lung is a sublobe.

20. The method of claim 19 wherein the system is further adapted to provide data on the graphical user interface regarding the highlighted region of the lung.
