Abstract
The present invention is a system and method for graphically displaying a three-dimensional model of a region located within a living body. A three-dimensional model of a region of interest is displayed on a graphical display. The location in three-dimensional space of a physical characteristic (e.g. a structure, wall or space) in the region of interest is determined using at least one probe positioned within the living body. The graphical display of the model is deformed to approximately reflect the determined three-dimensional location of the physical characteristic. Preferably, the probe or probes are moved throughout the region of interest so as to gather multiple data points that can be used to increase the conformity between the graphical display and the actual region of interest within the patient.

59. A method of graphically reconstructing a region of interest of a hollow anatomical structure having an interior surface and a space therein, comprising:
-
acquiring a plurality of anatomical points within the anatomical space, each of the anatomical points being automatically acquired at a specified time within a respective periodic cycle; and
generating a three-dimensional graphical representation of the region of interest based on the acquired anatomical points. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68)

69. A system for graphically reconstructing a region of interest on a hollow anatomical structure having an interior surface and a space therein, comprising:
-
a roving probe configured for being moved around within the anatomical space;
at least one localization processor configured for automatically acquiring three-dimensional locations of at least a portion of the roving probe and deriving anatomical points from the three-dimensional locations as the roving probe is moved around within the anatomical space; and
at least one graphical processor configured for generating a three-dimensional graphical representation of the region of interest based on the acquired anatomical points. - View Dependent Claims (70, 71, 72, 73, 74, 75)
