Abstract

A system and method for a medical intervention procedure within a cardiac chamber having an imaging system to obtain image data of the cardiac chamber and to create a 3D model from that image data, an interventional system to register the 3D model with a real-time image of the cardiac chamber and to display the 3D model, and an interventional tool positioned in the cardiac chamber to be displayed upon the interventional system and to be navigated in real-time over the registered 3D model. Preferably, the method and system also includes a storage medium to store the 3D model and wherein the interventional system receives the stored 3D model to register with the real-time image of the cardiac chamber.

Claims

1. A system for a medical intervention procedure within a cardiac chamber, the system comprising:

an imaging system configured for obtaining image data of a cardiac chamber and for creating a 3D model of the cardiac chamber from the image data;

a post-processing system configured for inserting at least three geometric markers in the 3D model for subsequent visualization, analysis, and registration, each of said three geometric markers corresponding with anatomical landmarks in the 3D model; and

an interventional system configured for registering the 3D model with a real-time image of the cardiac chamber utilizing the three geometric markers, and for displaying the 3D model.

2. The system of claim 1 further comprising:

an interventional tool configured for the medical intervention procedure, the interventional tool being displayable upon the interventional system and navigable in real-time over the registered 3D model.

3. The system of claim 2 wherein the interventional tool is a mapping-ablation catheter.

4. The system of claim 2 wherein the interventional system is a fluoroscopy system.

5. The system of claim 1 further comprising a storage medium configured for storing the 3D model, and wherein the interventional system is configured for receiving the stored 3D model for registering the 3D model.

6. The system of claim 1 wherein the imaging system is a CT system.

7. A method for a medical intervention procedure within a cardiac chamber including vessels thereof, the method comprising:

obtaining image data of a cardiac chamber from an imaging system;

creating a 3D model of the cardiac chamber from the image data;

inserting at least three geometric markers in the 3D model utilizing a post-processing system;

registering the 3D model with a real-time image of the cardiac chamber on an interventional system utilizing the at least three geometric markers;

displaying the registered 3D model on the interventional system;

positioning an interventional tool in the cardiac chamber;

displaying the interventional tool over the registered 3D model on the interventional system; and

navigating the interventional tool in the cardiac chamber using the registered 3D model.

8. The method of claim 7 wherein the 3D model includes endocardial views of the cardiac chamber.

9. The method of claim 7 wherein the imaging system is a CT system.

10. The method of claim 7 wherein the interventional tool is a mapping-ablation catheter.

11. The method of claim 7 wherein the interventional system is a fluoroscopy system.

12. The method of claim 7 further comprising:

storing the 3D model in a storage medium; and

transferring the stored 3D model to the interventional system for registering the 3D model.
