  1. The table includes the mean ± variance of SSIM and PSNR based on 4D-CT for five patients. The significance of 4D-sCT was evaluated using paired t test, and the significance of the differences between 4D-sCT generated by the two methods was assessed
  2. "–" indicates that no comparison was made
