First Claim
Patent Images
1. A method of displaying the coronary anatomy, superimposed on and complementing a 3D shape and function of a mammalian heart, comprising the steps of:
- (a) electronically generating a plurality of two-dimensional sections of a mammalian heart;
(b) subjecting said sections automatically to a segmental or helical pattern analysis to generate a three-dimensional model of said mammalian heart;
(c) subjecting said mammalian heart to angiography to obtain a picture of the coronary artery pattern of said mammalian heart;
(d) superimposing said coronary artery pattern on said three-dimensional model using as a reference for locating said coronary artery pattern relative to said model a structural element of said mammalian heart detected in said model; and
(e) displaying said model with said artery pattern superimposed thereon in a three-dimensional display.

Abstract
A method of displaying cardiac function which forms by helical or segmental analysis a three-dimensional cage model which can be shaded and color coded to indicate local and regional dysfunction by thickening or motion and stresses. On this model is superimposed the coronary artery tree including stenosed segments as obtained from the same patient by angiograms and the resulting three-dimensional coronary and mechanical model can be subjected to animation and analysis for diagnostic purposes and to simulate effects of treatment.

10. A method of displaying the function of a mammalian heart, comprising the steps of:
-
(a) generating a plurality of two-dimensional sections of a mammalian heart; (b) subjecting said sections automatically to a segmental or helical pattern analysis to generate a three-dimensional model of said mammalian heart; (c) analyzing said sections for ascertaining a presence of mechanical degradation of certain zones of the heart; (d) electronically coloring zones of the displayed model corresponding to said certain regions; (e) displaying said model with said colored zones; and (f) subjecting the model displayed in step (e) to video animation. - View Dependent Claims (11, 12, 13, 14, 15, 16)
