A breathing motion artifact reduction method is demonstrated which can be applied to a clinical shoulder imaging protocol and 1.) uses an orbital navigator (onav) signal to sense the breathing motion and 2.) uses a reconstruction from a reduced dataset to improve image quality. The motion signal from the navigator is used to control which data are used in the reconstruction.
