By capturing three dimensional motions of small markers on a heart of a small laboratory animal with 1000 fps stereo images, we realized a cardiac motion analysis system to quantify a rate of change of myocardial area on its heart, which indicates the myocardium's activity for rhythmic expansion/contraction motion in a local area. On the cardiac motion capture system, we actually analyzed three dimensional motion distributions of a heart of a rat model for myocardial infarction, whose heartbeat is 4 times/s or more. In the analysis, a characteristic cardiac motion in ischemic heart diseases was spatio-temporally quantified and visualized that infarction area on the heart of the rat caused by ischemia was spreading around its left ventricle.
