Fig. 4.

Example results from the phantom tests using respiratory traces 3 (A) and 6 (E). Corresponding MIP images are shown from acquisitions without gating or correction (uncorrected) (B) and (F) and corrected using B2B-RMC (C) and (G). For respiratory trace 3, the MIP image from data acquired with a 5-mm navigator gating window is also shown (D). Respiratory efficiency of the uncorrected and B2B-RMC images (B, C, F, G) is 100% and 54% the navigator gated image (d). Some residual fat is seen in all of the images (arrows).
