Recent years have seen a technological revolution in radiation oncology. Enhanced use of imaging combined with computer-controlled methods of dose delivery provides the capability of escalating tumor doses without increasing morbidity. A pivotal component of this modern technology is the computerized radiation treatment planning system (RTPS) which is used to develop the optimal treatment technique. Modern treatment planning systems make increased use of images, possibly from various imaging modalities, enhanced 3-D displays, more sophisticated dose calculation algorithms, more complex treatment plan evaluation tools, combined with the generation of images which can be used for treatment verification. In addition, the implementation of intensity modulated radiation therapy (IMRT) has added a further complexity to the RTPS and this is combined with automated optimization routines which are essential if IMRT is going to be used to its best advantage. A thorough commissioning of a modern 3-D RTPS has become a daunting task. This refresher course will review issues associated with the commissioning and quality assurance of a modern RTPS. The specific objectives of this review are:
1. To review the major functionality of a modern radiation therapy planning system.
2. To describe generic quality assurance (QA) concepts.
3. To provide an overview of commissioning a modern RTPS.
4. To provide an overview of the QA associated with a modern TPS.

近年来放射肿瘤学发生了一场技术革命。影像的广泛应用与剂量实施的计算机控制方法相结合提供了在不增加并发症率的同时提高肿瘤剂量的可能。这项现代技术的一个关键组成部分就是用于设计最优计划的治疗计划系统疗（RTPS）。现代治疗计划系统增加了影像的用途、可以使用不同的影像形式，增强了三维显示，采用更加成熟的剂量计算方法，更加成熟的治疗计划评估工具，还能生成用于治疗验证的图像。调强的应用使RTPS更加复杂，因为要体现调强的优势，RTPS还需要包括自动优化程序。一套现代三维放射治疗计划系统的完整验收已成为一项使人畏缩的任务。这个进修课程将回顾现代放射治疗计划系统验收和质量保证的要点：
1. 综述现代放射治疗计划系统的主要功能；
2. 介绍通用的质量保证概念；
3. 概述现代放射治疗计划系统的验收方法；
4. 概述现代放射治疗计划系统的质量保证程序。
