Abstract

This paper deals with the motion analysis and measurement of Epicardial tissues of the heart during MIDCAB (Minimal Invasive Direct Coronary Artery Bypass) and subsequently determines the effectiveness of a stabilizer used during this process. It involves measurement of the movement of muscles within and outside the stabilizer-using Image processing techniques based on which the surgeons' can determine the effectiveness of the stabilizer. We used a localization approach to measure the displacement of muscles. Comparisons were made with previous approaches that utilized global invariants such as the weighted PSNR method. It is found that the Standard deviation is lower with the localization approach, which means the accuracy of measurement obtained is better.
