(a) The k-space global angular sampling uniformity of ECG-gated GR (K=96, 12 simulated heartbeat) is dependent on the number of radial spokes within each heartbeat while the proposed segmented GR radial technique provides a much more uniform k-space sampling pattern. The reconstructed images (c–e) using the sampling pattern of conventional ECG-gated GR when M=178, M=189 and M=225 have variable degree of streaking artifacts due to non-uniform k-space sampling while the images obtained from segmented GR (b) have minimal streaking artifacts.
