In this work a joint cardio-respiratory motion estimation technique is introduced for the compensation of both the respiratory and cardiac motion of the heart during free-breathing cardiac MRI examinations. The proposed technique is combined with an extra-dimensional reconstruction scheme in which respiratory and cardiac motions are resolved. Initial results for 2D cine cardiac MRI are presented for synthetic and real data.
