Abstract

The invention relates to a method for the combined three-dimensional image display of a catheter. The catheter is inserted into the heart area of a patient with electrophysiological data, as part of a cardiological investigation or treatment. A current position of the catheter is localized with fluoroscopy-aided. The current position of the catheter and the electrophysiological data of the patient are blended into a three-dimensional volumetric image of a structure of the heart for the combined three-dimensional image display.

Claims

1-10. -10. (canceled)

11. A method for a three-dimensional image display comprising electrophysiological data of a heart of a patient and a catheter inserted into the heart of the patient, comprising:

generating a three-dimensional volumetric image of a structure of the heart;

registering the three-dimensional volumetric image relative to a coordinate of a biplanar X-ray system;

recording two X-ray projections of the catheter in two different directions by the biplanar X-ray system;

determining a current position of the catheter by feedback projecting the two X-ray projections of the catheter;

generating the electrophysiological data; and

blending-in the current position of the catheter and the electrophysiological data into the three-dimensional volumetric image for the three-dimensional image display.

12. The method as claimed in claim 11, wherein the three-dimensional volumetric image of the structure of the heart is recorded pre-procedurally.

13. The method as claimed in claim 11, wherein the three-dimensional volumetric image of the structure of the heart is recorded intra-operatively.

14. The method as claimed in claim 11, wherein the current position of the catheter is blended into the three-dimensional volumetric image via ECG-triggered.

15. The method as claimed in claim 11, wherein the electrophysiological data comprises a position of an ablation or a mapping point of the current position of the catheter in the three-dimensional volumetric image of the structure of the heart.

16. The method as claimed in claim 15, wherein the ablation or the mapping point is color-coded blended into the three-dimensional volumetric image of the structure of the heart.

17. The method as claimed in claim 11, wherein the three-dimensional image display is controlled by a user for rotating, enlarging, or reducing.

18. The method as claimed in claim 11, wherein the current position of the catheter is displayed by a color or flashing in addition to the electrophysiological data.

19. The method as claimed in claim 11, wherein the current position of the catheter is three-dimensional.

20. A medical device, comprising:

a biplanar X-ray system that records two X-ray projections of a catheter to be inserted into a heart of a patient in two different directions;

an electrophysiological measuring device that generates an electrophysiological data of the heart of the patient; and

a computer that;

registers a three-dimensional volumetric image of a structure of the heart relative to a coordinate of the biplanar X-ray system,

determines a current position of the catheter by feedback projecting the two X-ray projections of the catheter,

blends-in the current position of the catheter and the electrophysiological data into the three-dimensional volumetric image, and

displays the three-dimensional volumetric image blended in the current position of the catheter and the electrophysiological data.
