Three-dimensional dynamic MRI (3D-DMRI) is a promising method to analyze respiratory mechanics. However, current 3D DMRI implementations offer limited temporal, spatial resolution and volume coverage. In this work we demonstrate the feasibility of three compressed sensing reconstruction methods along with view-sharing method with clinical evaluation on 8 healthy subjects by expert radiologists. BCS scheme provides better performance than other schemes both qualitatively and quantitatively. The preliminary results on lung volume changes demonstrate the clinical utility of the BCS scheme.
