Table 2.
TCP and NTCP values for the TG-166 water phantom irradiated with the UCSF 6 MV Primus beam calculated with TOPAS and Pinnacle. Statistical uncertainties are shown in the parenthesis and are due to the Monte Carlo calculation only. The adaptive convolution algorithm was used to calculate the dose in Pinnacle. S-Model results from TG-166 are shown in the first row.
