The implemented PEPTIDE reconstruction pipeline. Reconstructions are performed on a blade-by-blade basis, first applying a GRAPPA undersampling reconstruction, as for EPTI, prior to applying motion correction strategies, as for PROPELLER. Calibration data is matched to the orientation of each blade acquisition and can be further updated to compensate for calculated rotational subject motion. Finally, the reconstructed blades can be gridded and combined with appropriate weighting.
