A new self-gating acquisition scheme allowing the retrospective reconstruction of several respiratory phases is proposed. This approach takes advantage of the recently introduced Golden-Radial Phase Encoding (G-RPE) trajectory and uses the, inherently acquired, central k-space profiles to derive the respiratory motion signal. The method was tested in in-vivo data using a 32-channel coil and 3 different respiratory phases were reconstructed from undersampled data using non-Cartesian SENSE reconstruction.
