In this work, a sparsity-enforced Kalman filter technique for dynamic cardiac imaging is presented. The Kalman filter is firstly casted into a framework of optimization, and then a sparsity constraint is incorporated to the framework for better motion capture of the imaging object. Applications to cardiac dynamic MRI clearly demonstrated the strength of the proposed method.
