May facilitate robust arteriogram tracking; leaves open clinical validation for myocardial dysfunction assessment.
A new method of correspondence analysis on the basis of geometrical similarity in tracking the region of interest (ROI) of coronary arteriograms is described. The method is insensitive to scaling, rotation, and gray-level variation. Experiments also show that the algorithm is valid even when large deformations exist. It is an important step toward a new approach to regional myocardial dysfunction analysis.
