基于知识的放射治疗技术研究

文章介绍了基于知识的放射治疗技术（KBRT）相关概念和KBRT技术的实现方法，重点介绍了KBRT中的特征检索法以及在机器学习上的应用。随后回顾了当前KBRT在多部位肿瘤放疗中的应用及对于剂量学评价标准的改进、KBRT模型相关参数和离群值的研究以及KBRT与多种放疗技术相结合等研究热点。文章还指出了KBRT技术在现阶段遇到的问题和挑战，从而进一步提出了KBRT在今后研究中的发展方向，并对KBRT在多中心合作、自适应放疗以及在机器学习方法的深入研究等相关话题展开讨论。

Research on knowledge-based radiation therapy

Abstract: This paper introduces the related concepts of knowledge-based radiation therapy (KBRT) and the implementation methods of KBRT technology, with emphasis on the featured retrieval method in KBRT and its application in machine learning. This paper then reviews some research hotspots such as the current application of KBRT in different kinds of tumor radiotherapy, the improvement of dosimetric evaluation standards, the study of related parameters and outliers of KBRT model, and the combination of several radiotherapy technologies. This paper also points out the problems and challenges encountered in the current stage of KBRT technology, thus further suggesting the development direction of KBRT in future research and discussing the related topics such as KBRT in multicenter cooperation, adaptive radiotherapy and in-depth study of machine learning methods.
