摘　　要：目的:探讨宫颈癌患者常规放疗的最佳体位。方法:选择宫颈癌常规放疗患者10例,5例行等中心定角仰卧照射,5例行等中心定角俯卧照射,每位患者每周在模拟定位机上重复摆位验证3次,将验证图像与同一患者定位图像骨性标记点A到X、Z轴的垂直距离进行比较,求出在X、Z轴方向上的偏移。将仰卧照射、俯卧照射所得数据进行比较。结果:仰卧照射与俯卧照射所得数据在X、Z轴方向有统计学差异(P<0.05)。结论:宫颈癌盆腔常规放疗患者俯卧位因摆位误差小而优于仰卧位。Objective To discuss the appropriate position of conventional radiotherapy for cervical cancer patients.Methods Ten cases of cervical cancer patients were selected,5 patients underwent fixed angle source axis distance conventional radiotherapy by supine position,the other 5 patients by prone position,each patient was verified by repeated setup on the simulator 3 times per week,so as to compare the vertical distance of the verified images with that of the skeletal A marked point to the X-,Z-axis of the positioning image for the same patient and find the offset of the X-,Z-axis direction.The data of supine and prone position were compared.Results There were significant difference between the supine and prone position in the X-,Z-axis direction（P0.05）.Conclusion Prone position is better than supine position of conventional radiotherapy for cervical cancer due to the smaller setup errors.[Chinese Medical Equipment Journal,2012,33（6）：63-64,100]
