In the era of intensity-modulated radiation therapy, classical conformal radiotherapy (CRT) is still a popular treatment technique in routine practice, especially in developing countries. Therefore, CRT treatment planning is still an important task of physicists and dosimetrists. This talk will first briefly review the procedure of CRT treatment planning. Then it will answer the most-frequently asked questions during the planning procedure. The questions are “how to select beam orientations”, “how to choose beam energy”, “how to determine beam shape, “how to determine beam weights and wedges”, and “how to evaluate treatment plans”. Finally it will introduce two practical techniques that are the splitting-field technique and field-in-field technique.

在调强放疗的时代，经典的适形放疗技术仍然是一种经常用到的技术，尤其是在发展中国家。因此，设计适形放疗的计划设计甚然是物理人员的一个重要工作内容。这个报告将首先简单地回顾适形放疗计划设计的过程。然后回答一些在计划设计过程中经常被问到的一些问题。这些问题是“如何选择射野方向”、“如何选择射野能量”、“如何确定射野权重和楔形板”和“如何评价治疗计划”。最后，这个报告将介绍两种实用的照射技术，即分裂野技术和野中野技术。
