摘　　要：介绍了三维放射治疗计划的坐标系统。阐述了以等中心坐标系、人体坐标系、射束坐标系为基础的坐标体系，推导了它们之间的坐标变换解析式，说明了坐标系的应用和相关处理方法。该系统组织严紧、结构优，对提高 3D-TPS 的整体性能具有重要意义，有很好的实用性和通用性。This paper describes the coordination systems of a three dimension radiation treatment plan. The coordination systems refer to the body coordination , the isocenter coordination and the beam coordination. We have derived the analytical equations for coordination transforms, indicated the applications of the coordination systems , and provided corresponding treating means. With strict construction and perfect structure, the systems have an important significancing for increase the whole capability of a three dimension radiation treatment plan, and can be extensively and flexibly used.
