Prediction of the respiratory and beating motion of the heart has several useful applications in cardiovascular MRI. Despite its usefulness, there is currently no available technique that establishes a predictive model of both cardiac and respiratory 3D motion. The main bottleneck is the inherent slow nature of MRI that prevents obtaining real-time 3D images of the heart with both high spatial and temporal resolution. In this work, we present a novel technique that predicts 2D real-time images for any cardiac and respiratory motion state. By combining several 2D acquisitions, the method predicts 3D images of the heart, including through-plane motion.
