剂量对比研究对确保临床试验的统一辐射剂量给药具有相当重要的意义。本文研究了拉合尔国际剂量学调查团以及核医学与肿瘤学协会(INMOL)所做的X射线高功率直线加速器的性能对比分析。实验采用基于国际原子能机构(IAEA)关于吸收剂量-水剂量标准TRS-398协议的柱形电离室进行测量,偏差百分比为0.5%-1%。研究发现拉合尔INMOL关于直线加速器输出特性的实验结果与IAEA剂量调查团的研究结果一致。 Dose contrast studies are of great importance to ensure uniform radiation dose administration in clinical trials. In this paper, a comparative analysis of the performance of the X-ray high-power linear accelerator made by the International Cooperative Investigation Mission in Lahore and the National Institute of Nuclear Medicine and Oncology (INMOL) was conducted. Experiments were performed using a cylindrical ionization chamber based on the International Atomic Energy Agency (IAEA) protocol TRS-398 for absorbed dose-water dosages, with a percent deviation of 0.5% -1%. The study found that Lahore INMOL experimental results on the linear accelerator output characteristics consistent with the findings of the IAEA Dose Mission.
