医用高能加速器输出剂量、能量和均整度的监测，是临床体外放射治疗最基本的质量保证措施。本文介绍了对上述剂量学物理参数常规的测试方法和数据处理，并以坐标图形式描述了菲力普医用ＳＬ７５一２０型高能直线加速器六年来的高能Ｘ线、高能电子束线和表征能量的半值水深机器剂量学宏观面状况。本文还对该加速器六年来的监测数据进行了处理，从数学处理后的结果综合评价了该加速器的临床剂量学指标，并在一定误差范围内量化了肿瘤体外放射治疗处方量，但处方量综合误差合成还有待于治疗中其它环节的取材统计，并需作进一步的探索。
Monitoring the output dose, energy, and evenness of the medical high-energy accelerator is the most basic quality assurance measure for clinical external radiation therapy. This article describes the conventional testing method and data processing of the above dosimetric physical parameters, and describes in a graph the high-energy X-ray, high-energy electron beam lines and energy characterization of the Philip SL75-20 high-energy linear accelerator for six years. Half-value water depth dosimetry macroscopic condition. This article also processed the monitoring data of the accelerator for six years, and comprehensively evaluated the clinical dosimetry indicators of the accelerator from the mathematically processed results, and quantified the amount of tumor external radiation therapy prescription within a certain error range, but the prescription quantity was comprehensive. The error synthesis still needs to obtain the statistics of other links in the treatment and needs further exploration.
