Abstract: 

Magnetic resonance imaging (MRI) is increasingly used in clinical settings to image the anatomy and physiological function of the cardiovascular system.  While the image acquisition can be done in a reasonable amount of time, the analysis of these images to obtain quantitative measures of cardiac function is time consuming and requires considerable manual intervention.  Consequently, only left ventricular volumes are measured at two points in the cardiac cycle, end-diastole and end-systole, to obtain stroke volume and ejection fraction.  In this talk, techniques are presented to leverage the manual analysis that is typically done at two time points in the cardiac to compute parameters of cardiac function and shape throughout the cardiac cycle.  Techniques for analyzing advanced cardiac MRI such as tagged MRI and phase contrast MRI are presented along with future directions including machine learning based techniques for automating the image analysis process for cardiac MRI.
