© 2015 IEEE. Local contractility evaluation is a promising area of cardiovascular research. We propose strain (local deformation measure) calculation method based on 2d non-rigid image registration on CINE magnetic resonance imaging data. First we register pairs of consecutive images in time series then we apply the results to whole study. Presented 2d approach is stable and faster then 3d or 3d+t methods. We validated results against two Grand Challenges (2009 Left Ventricle Segmentation and 2011 Motion Tracking). Both tracking myocardial contours and tracking points give satisfactory results. We show that our approach gives similar information as ejection fraction on global level.
