Planning CT, w1CBCT and sCT slices for two patient cases along with residual images between w1CBCT/pCT (MAE 216.19 HU) and sCT/pCT (MAE 31.47 HU). Histograms of residual images show that the sCT image residual errors are concentrated around 0 HU largely contained within ± 100 HU whereas w1CBCT images show extremely large differences compared to pCT.
