The purpose of this talk is to present an overview of the clinical IMRT procedure and issues related to the implementation of the new radiation modality. We will report on the current status of IMRT practice and discuss a series of clinical questions, such as the importance of patient localization and immobilization, performance of the inverse planning optimization, how much of an improvement can intensity modulation makes to radiotherapy dose distributions, the accuracy of the dose model and delivery system, and the efficiency of the dynamic/static MLC delivery algorithm of the system, and treatment verification.
本讲的目的是讲述调强放射治疗的临床过程和实施中的具体问题。本报告将讲述目前调强放射治疗的现状，讨论一系列的临床问题，比如病人定位和固定的重要性、逆向计划优化的表现、调强放射治疗对剂量分布的改善程度、剂量计算模型和治疗实施系统的准确性、动态/静态多叶准直器调强分子野算法的效率和治疗验证等问题。
