Procedures for Dosimetric Monitoring of the Radiation Parameters of Clinical Linear Electron Accelerators

Resumo

Procedures for dosimetric monitoring of the radiation parameters of the latest generation of linear electron accelerators for morning and pre-therapeutic testing of plans for irradiation of patients are discussed. It is found that the deviations in the radiation yield of the accelerators lie within the international tolerance of ±2% and the width of the leakage peaks is less than 7 mm. It is shown that for intensity modulated radiation therapy, the calculated and measured values agree to within 75–100% for 95% of irradiation plans.
