Radiation treatment planning has developed into a substantial and effective component of the entire radiation treatment approach. Over the last 2 decades, with the development of high energy electron and x-ray sources, and also with the availability of new radionuclides and techniques for internally applied radiation, all of which permit a high degree of concentration of radiation, treatment planning has been developed to make best use of these modalities. The use of automatic computation has proved necessary in order to handle the large amounts of radiation data involved in treatment dose calculation. Tumor and anatomical localization has been carried out with increasing precision. Several cases are described which illustrate planning and in particular the use of computerized transverse tomography. The use of moving shadow-shields is also described. For internally applied radiation, the features of iodine-125 are illustrated.
放射治疗计划已发展成为整个放射治疗方法中一个重要且有效的组成部分。在过去20年里，随着高能电子和X射线源的发展，以及新的放射性核素和内照射放射技术的出现，所有这些都使得放射能够高度集中，放射治疗计划得以发展，以便充分利用这些方式。事实证明，为了处理治疗剂量计算中涉及的大量放射数据，使用自动计算是必要的。肿瘤和解剖定位的精度越来越高。文中描述了几个案例，阐述了治疗计划，特别是计算机断层扫描的应用。还介绍了移动铅挡器的使用。对于内照射放射，阐述了碘-125的特性。
