The DAP for each patient was used as the input dose parameter and the collected information from the RDSR relating to kVp and beam filtration was used to define the beam quality in PCXMC. The patient position relative to the gantry did not change drastically between each patient case, and thus, the geometric setup in PCXMC was kept constant during the simulation of each procedure. In reality, there may have been minor changes in the geometric configuration, due to different body morphology of the patients and operator preferences. The median effective dose was reported from the PCXMC output.
