Abstract
We describe the dosimetric characteristics of a newly introduced dual photon energy linear accelerator, the Varian Clinac 1800. Depth doses are compared with other accelerators of the same nominal accelerating potentials (6 and 10 MV). Field flatness at dmax and at 10 cm depth, depth of dmax, wedge characteristics, output factors, and doses in the buildup region are presented.
摘要
我们描述了一种新引入的双光子能量直线加速器——瓦里安Clinac 1800的剂量学特征。将其深度剂量与其他具有相同标称加速电位（6和10兆伏）的加速器进行了比较。给出了在最大剂量深度（dmax）和10厘米深度处的射野平坦度、dmax深度、楔形特征、输出因子以及建成区剂量。
