医用直线加速器的X射线剂量的实验研究

摘要

The paper described the measurements of basic parameters for medical electron linem accelerator dosage distribution.The ion chamber and film were used as detector during the measurements of PDD、TMR and OAR, etc, which are the key data for determining the accelerator X-ray energy and for quality control in clinical application.%本文介绍了用于测量电子直线加速器剂量的电离室和胶片探测器。用这些探测器测量了电子直线加速器在方型和圆形野情况下的几种重要的剂量分布，如百分深度剂量、组织最大比、离轴比等。文中介绍了用这些探测器测量这些参数时的特点。
