Abstract:
1. A method for providing diagnostic information using endocardial surface data for a patient's heart, the method comprising: receiving endocardial surface data for the left ventricle of a heart, wherein the endocardial surface data represents the endocardial surface of the left ventricle at multiple times over a heartbeat, the multiple times comprising end diastole and end systole of the heartbeat, and wherein the endocardial surface data is obtained using a volumetric imaging application; generating a representation in prolate spheroidal coordinates of the endocardial surface of the left ventricle at end diastole and end systole using the endocardial surface data, wherein the prolate spheroidal coordinates comprise a longitudinal angular coordinate μ, a circumferential angular coordinate θ, and a coordinate λ as a function of longitudinal angular coordinate μ and circumferential angular coordinate θ, and wherein λ computing three-dimensional fractional shortening (“3DFS”) of the left ventricle as 3DFS=(λ
