射波刀治疗肝细胞癌的影像引导定位追踪研究进展

Research progress on image-guided localization and tracking in CyberKnife treatment of hepatocellular carcinoma

  • 摘要: 射波刀具有放疗靶区重复性好、治疗精度高、创伤小等特点,对运动肿瘤可实现实时追踪和立体定向放射治疗。对于放射治疗过程中受呼吸运动影响较大的肝内肿瘤,射波刀可精确定位、设计计划和治疗。本文基于肝细胞癌,对射波刀的结构与迭代、影像追踪模式及其优缺点、常用金属标志物的追踪模式和模式优化方法,以及植入金属标志物后的定位问题进行综述。

     

    Abstract: CyberKnife has the characteristics of good repeatability of radiotherapy target, high precision and less trauma. It is a stereotactic body radiation therapy system for real-time tracking of moving tumors during treatment. For intrahepatic tumors being highly affected by respiratory movements in treatment, CyberKnife provides precise positioning, planning, and treatment. This paper focuses on the treatment of hepatocellular carcinoma (HCC) using CyberKnife, and reviews as following: the structure and iteration of CyberKnife; image-tracking modes and their advantages and disadvantages; tracking modes of common fiducial markers and their optimization methods, the positioning problems after the implantation of fiducial markers.
