Abstract
The end diastole and end systole images from an acquired cardiac loop are shown side by side on an image display for automatic border tracing. The border tracings can be used to calculate ejection fraction in real time. The cardiac loops may be first acquired then processed for automatic border definition, or the acquired images can be processed in real time to indicate their suitability for automatic border detection as they are acquired.
