Abstract

This paper presents estimation algorithms for the analysis of heart motion and deformation over a cardiac cycle, as well as the visualization techniques for the animation of moving heart evolution. We devote the first part of the paper to the analysis of the heart motion and deformation. The research is based on the general belief that the human heart undergoes both global motion and local deformation, and is conducted on the angiographic data of the heart. We identify the global motion as the relative position and orientation change of the heart as a whole and estimate the motion parameters from the 3-D data of the bifurcation points. We also develop a recursive algorithm for estimating global motion and object shape in order to combat the biased distribution of the bifurcation points. Upon compensation for the global motion, a tensor analysis based approach is introduced to parameterize the deformation of localized region. The estimated stretch tensors give the directions and magnitudes of extreme deformation for each localized region. In the second part of the paper, we present several visualization techniques to vividly examine the spatial and time varying nature of the heart.
