为了解鼻咽癌患者普通摆位方法的位移情况,并探讨准确摆位方法的效果,我们于1991年9月～1992年3月做了下述研究,报告如下。 1 资料与方法 一般资料:10例病理证实的鼻咽癌患者,男6例,女4例,年龄42～66岁。用光野灯清晰的AECL产Theratron780C~(60)Co治疗机作固定野治疗,研究耳前野和颈部切线野位移情况。 摆位方法:每例患者前10次治疗用普通摆位法研究,后10次用准确摆位法对照研究。普通摆位法为光野灯对准皮肤野摆位,辅以小砂袋固定头部;准确摆位法为先模拟机等中心定位,在病人面颈皮肤作三束激光定位灯十字中心标记;治疗时用三束激光灯和光野灯双核对准确摆位,然后使用我们研制的咬嘴式头部
In order to understand the displacement of the ordinary setting method for patients with nasopharyngeal carcinoma and to investigate the effect of accurate positioning methods, we conducted the following studies from September 1991 to March 1992. The report is as follows. 1 Materials and Methods General Information: 10 cases of pathologically confirmed nasopharyngeal carcinoma patients, 6 males and 4 females, aged 42 to 66 years old. A field lamp clear AECL Theratron 780C ~ (60) Co treatment machine was used as a fixed field treatment to study the wild field and neck tangential field displacement. Placement method: The first 10 treatments for each patient were studied with the normal setting method, and the latter 10 times were compared with the accurate setting method. Ordinary setting method is that the light field lamp is aligned with the skin wild position, and the small sand bag is used to fix the head; the accurate setting position method is the first position of the simulator center, and the center mark of the three laser positioning lights is made on the patient’s face neck skin; When using a three-laser and field lamp dual-core to accurately position, then use our developed mouthpiece head
