Abstract
Method and apparatus for detecting and analyzing heart mechanical activity at a region of interest of a patient's heart are provided. The method comprises acquiring a time sequence of 2-dimensional X-ray images of a region of interest over at least part of a cardiac cycle; detecting coronary vessels in the X-ray images; tracking the coronary vessels through the sequence of images to identify movements of the coronary vessels; and analyzing the movements of the coronary vessels to quantify at least one parameter characterizing heart wall motion in the region of interest.
