Abstract:
Objective To calibrate the dose of 12MeV high-energy electron for Siemens MD7745 medical linear accelerator.Methods The international protocols,contents and technical standards were expatiated.Some existing problems in dose calibration of high-energy electron were analyzed.Results The working precision met the requirement of quality assurance in radiotherapy by WHO.Conclusion In order to improve the therapeutic effect,the dose must be calibrated,and the error in dose calibration of high-energy electron should be reduced to the lowest.
