| 中文摘要: |
| 调强放疗技术在实现精确治疗的同时，也使临床治疗前的剂量验证变得更复杂。目前被广泛采用的实验测量的方法尽管较为准确有效，但同时也存在耗时耗力的缺点。而独立的剂量算法（深度剂量-离轴比、Clarkson积分、卷积、蒙特卡罗）验证在保证一定精度的条件下可以部分解决这些问题。这给临床工作者节省了大量的时间和精力，也成为当今国内外研究的热点和剂量验证的重要发展方向。本综述主要对基于修正和基于模型的独立剂量验证方法进行介绍，并简要论述调强放疗计划剂量验证技术的发展趋势。 |
| 英文摘要: |
| With the rapid development of intensity modulated radiation therapy (IMRT) technique, the accuracy of radiotherapy has improved, while the pretreatment dose verification has become more complex. Although the experimental measurements, a widely used way to perform dose verification, is accurate and effective, its time-consuming and labor-intensive is still a challenge for physicist. The independent dose verification method such as the depth dose-off axis ratios (OAR) empirical model, Clarkson integral model, convolution model and Monte Carlo model, could partially solve these problems effectively when the accuracy is ensured within a certain range. This approach could save physicists' time to conduct dose recalculation and plan check, and has become the hotspot in the world. This paper, therefore, mainly introduces the correction-based and the model-based independent dose verification methods, and briefly discusses the development of dose verification for IMRT plans. |
