Abstract
Medical navigation and mapping system and methods are disclosed for modeling both unobstructed and obstructed portions of a catheter. An exemplary system includes a rendering component operatively associated with an output device. The rendering component overlays a plurality of data images on one another to generate a three-dimensional image representing both the internal tissue and a visible portion of a catheter body. An enhancement component is configured to overlay a silhouette on the three-dimensional image. The silhouette represents an obstructed portion of the catheter body.
Claims20
A medical navigation and mapping system, comprising:
- a rendering component operatively associated with an output device, the rendering component configured to receive position data associated with a catheter body of a catheter and overlay a plurality of data images on one another to generate a three-dimensional image representing both internal tissue and a visible portion of the catheter body;
- and
- an enhancement component configured to overlay a silhouette on the three-dimensional image, the silhouette representing an obstructed portion of the catheter body using the positional data associated with the catheter body.
A medical navigation and mapping system, comprising:
- a rendering component configured to generate a three-dimensional image based on mapping information associated with a catheter body of a catheter and internal tissue, the three-dimensional image representing an outer boundary of the internal tissue and a visible portion of the catheter body relative to the outer boundary of the internal tissue;
- and
- an enhancement component configured to overlay a silhouette of an obstructed portion of the catheter body on the three-dimensional image.
A method for mapping cardiac tissue and graphically illustrating both unobstructed and obstructed portions of an electrode catheter, comprising:
- obtaining mapping coordinates from an electrode catheter inserted into a chamber of a heart, the mapping coordinates representing a surface of the heart;
- generating a three-dimensional image based on the mapping information, the three-dimensional image showing the surface of the heart and a visible portion of the electrode catheter;
- generating a plurality of candidate silhouette fragments representing a body of the electrode catheter;
- determining which candidate silhouette fragments are obstructed by other visible objects in the three-dimensional image;
- and
- overlaying a silhouette of at least one obstructed portion of the electrode catheter using only those candidate silhouette fragments obstructed by other visible objects in the three-dimensional image.
