Mitral Valve Annulus Matching over Time Based on Image Intensities

Abstract:

The mitral valve annulus shape is complex but vital for normal functioning mitral apparatus. In this paper, mitral valve annulus curves at different time instances were matched with image intensities as similarity metric. The quality of matching is described by a cost function, involving a predominant term qualifying the matching quality---image intensities. To ensure the smoothness of the solution to the minimization problem, regularization term was added to generate combined cost functional. Numerical simulation results verified the effectiveness of our method.
