| 目的 探讨头颈部肿瘤3D-CRT实施过程的质量控制(QC)方法。方法 采用拓能系统的固定装置、计划系统、激光灯、弓形尺、头部模型(简称头模)模拟3D-CRT的实施过程进行质量控制分组实验。结果 复位标记标在固定装置以及面罩开窗处患者皮肤上的B组,实施过程误差小于复位标志标注在面罩上的A组。能达到3D-CRT过程QC要求。结论 开展头颈部肿瘤3D-CRT必须合理使用头部固定装置。严格按本文规定标准方法操作可达到3D-CRT的实施过程的QC要求。 |

| Objective To discuss the quantity control methods for the practice process of three-dimension conformal radiation therapy(3D-CRT) of the head and neck cancers. Methods To do quality control experiments to simulate the process of 3D-CRT by means of Topsland system,radiation treatment -planning system,laser light,bow form ruler,head model. Results Group B with the tag of reposition on the skin had less error in process than group A with the tag of reposition on the veil.It could reach the QC requirement of 3D-CRT process. Conclusions Head fixing equipment should be used reasonably when 3D-CRT of the head and neck cancer is performed.The patient's coordinates should be founded on the skin,and every link in process ought to be reposited according to the patient's coordinates and validated by photograph before treatment.The QC requirement of the process can be reached if the operation is performed strictly following the standard method stated in this paper. |
