This describes the schematics of iNAV respiratory motion correction when applied to dual-phase 3D WH bSSFP. A separate iNAV reference (iNAV REF) was used for systole (a) and diastole (b). All subsequent systolic and diastolic iNAVs (e and f) were registered to their respective reference iNAV (a and b respectively) using normalized cross-correlation (nCC). Images c and d show the reconstructed images obtained
