A volume can be reconstructed from each sagittal slice, each giving its own correlation coefficient over all time points; here we report the median across these slices. The best result for each volunteer is shown in bold. The cardiac gating for the acquisition of data for volunteers A-D results in more accurately reconstructed volumes than is the case for E-H, but in both cases the weighted MA scheme is beneficial.
