SYSTEM AND METHOD FOR REAL-TIME SURFACE AND VOLUME MAPPING OF ANATOMICAL STRUCTURES
First Claim
1. A method for three-dimensionally mapping a volume within a region of interest (ROI) located within a body, comprising the steps of:
- tracking the position of an invasive medical device within said ROI in real-time, said tracking step comprising the substeps of;
computing a contour for said medical device as a function of at least one of a shape constraint and a positional constraint; and
translating said contour into a plurality of three-dimensional positions wherein said plurality of three-dimensional positions include both known and virtual positions based on said at least one of said shape and positional constraints;
determining a real-time spatial volume based on at least one of said virtual three-dimensional positions; and
rendering a real-time three-dimensional graphical representation of said spatial volume.

Abstract
A method and system for mapping a volume of an anatomical structure includes a processor for computing a contour of a medical device as a function of positional and/or a shape constraints, and to translate the contour into known and virtual 3D positions. The processor is configured to determine a spatial volume based on a virtual position, and to render a 3D representation of the spatial volume. A method and system of mapping a surface of an anatomical structure includes a processor configured to obtain an image of the structure. The processor is further configured to receive a signal indicative of a medical device contacting the surface of the anatomical structure, and to determine a position of the device upon when contact has been made. The processor is configured to superimpose marks on the image indicative of a contact points between the device and the structure.

12. A method for mapping a surface of an anatomical structure in real-time, comprising the steps of:
-
obtaining an image of said anatomical structure; determining a real-time position of a medical device when said medical device contacts said anatomical structure; and superimposing on said image a mark corresponding to said position of said medical device to indicate said anatomical structure was contacted at the point on said anatomical structure where said mark is disposed.
