A motion-guided low-rank plus sparse (L+S) approach for reconstruction of respiratory motion fields is presented for dynamic MRI of the lungs with high spatiotemporal resolution. Motion-guided L+S represents a paradigm shift where motion fields that describe deformations between respiratory phases are reconstructed instead of the respiratory phases themselves. The technique is demonstrated for normal and deep breathing imaging and compared against standard L+S reconstruction.
