Workflow of the data analysis. The planning CT (pCT) was deformably registered to the CBCT to generate the dCT which has reduced anatomical differences with respect to the CBCT compared to the pCT. The CBCTc was generated using the acquired CBCT. For the CTBCTb a step-wise HU to mass-density conversion curve was calculated. The dose calculated on the CBCTc and CTBCTb were compared to the dose calculated on the pCT and the dCT, respectively
