加速器辐射质测量方法的比较分析
Comparative Analysis of Measurement Methods for Accelerator Radiation Quality
摘要
Abstract
According to the different measurement methods of accelerator high-energy photon beams radiation quality,the dose ratio (D20/D10) calculated by the formula and the tissue phantom ratio (TPR20.a0) measured by direct experimental,measuring charge in a certain period of time or in a certain Monitor Units is proposed.The radiation quality of 6M-V,10MV and 25MV photon beams are measured respectively at the clinical linac laboratory in National Institute of Metrology(China).The results show that the uncertainty of accelerator high-energy photon beams radiation quality measured in a certain Monitor Units is obviously smaller than measured in a certain period of time,and the certain Monitor Units method of 6 MV,10 MV,25 MV using D20/D10 to calculate the value of the values of TPR20,10 were smaller than 0.27％,0.31％,0.35％.关键词
