Fig 2. Example of feature tracking using CVI42, endocardium (red) and epicardium (green) contours manually traced on the SSFP cine short axis stack, long axis in cine 4 chamber, 2 chamber and LVOT series during end diastole and systole.

The yellow dots between the red and green contours correspond to the myocardium which is tracked during systole for feature tracking GLS.
