We propose a self-gated imaging method using navigator projections acquired at high spatiotemporal resolution and gated retrospective reconstruction, with the aim to provide high-quality kinematic joint imaging with minimal patient setup and no mechanical apparatus. Preliminary 2D imaging results of the knee in 3T have shown that the joint in motion can be clearly visualized from the automatically reconstructed cine.
