Abstract：Objective To perform a clinical evaluation of the electron beam model of the Oncentra treatment planning system. Methods The dose value were calculated by the Oncentra treatment planning system and compared with the real value that were validated by measurements of five grades of electron beams and percentage depth dose in an IBA 3D (Three Dimensional) water phantom. Comparisons were also made among the calculations of the Oncentra treatment planning system with and without boluses as well as corresponding references. Results The discrepancies between the calculations achieved by the Oncentra treatment planning system and the IBA 3D water phantom were found less than 2%. And the dose changes induced by boluses were in line with the corresponding references. Conclusion The electron beam model for the Oncentra treatment planning system had proven its correctness and stability.
