摘要:
精确的剂量照射是立体定向放射外科治疗成功的关键。Zap-X系统是一款具有自屏蔽功能的辐射治疗设备，用于脑部及头颈部肿瘤的立体定向放射外科治疗。本研究针对Zap-X系统的相关技术特点进行简述，分别从机械结构、自屏蔽系统、机械运动系统、辐射准直器系统、治疗计划系统、kV图像引导系统、MV影像验证系统等方面着重介绍了Zap-X系统的组成，阐述该系统的治疗过程，并总结对比其临床应用，最后对该系统的未来发展方向提出展望。其旋转式准直器的设计加上自身屏蔽防护的设计极大地降低了设备安装成本，可移动式MV探测器能实时监测治疗过程中的剂量准确性，采用直线加速器代替放射源，安全性、稳定性得到一定程度的提高。作为系统的初代产品，该设备还有诸多技术环节有待进一步改善。
Abstract:
Abstract: Precise dose delivery is the key to the success of stereotactic radiosurgery. Zap-X system is a kind of radiotherapy equipment equipped with self-shielding function for the stereotactic radiosurgery of tumors in the brain, head and neck. Herein the technical characteristics of Zap-X system are briefly described, introducing the composition of Zap-X system from mechanical structure, self-shielding system, mechanical movement system, radiation collimator system, treatment planning system, kV image guidance system and MV image verification system. The treatment process of the system is explained and its clinical application is evaluated. Finally, the future development of the system is discussed. The designs of the rotating collimator and self-shielding protection greatly reduce the installation cost of the equipment. The removable megavoltage radiation detectors can monitor the dose accuracy during the treatment process in real time. The use of linear accelerator instead of radioactive source makes it safe and stable to a certain extent. As the first-generation product of the system, more technical aspects still need to be further improved.
