摘要
目的探讨头颈肩面罩固定体位在胸部肿瘤放疗中的应用效果。方法 96例胸部肿瘤患者随机分为头颈肩面罩组和真空袋组各48例,分3次拍摄验证片,以数字重建放射影像(DRR)图中心"十"字点为坐标,测量验证片上中心"十"字点,比较分析其在X、Y、Z轴上的偏移。结果两组的中心点平均偏移在Y和Z轴上差异均有统计学意义(P<0.05),在X轴上差异无统计学意义(P>0.05)。结论与真空袋相比,胸部肿瘤放疗用头颈肩面罩固定体位能够减少摆位误差,提高体位精准度,且步骤简单易行,值得临床推广。
Objective To explore the application effect of fixed position of head-neck-shoulder mask in radiotherapy of thoracic tumor. Methods 96 cases of patients with thoracic tumor were selected and randomly divided into head-neck-shoulder mask group and vacuum bag group, with 48 cases in each group. The verification films were taken 3 times. Take center " 十 " point of digitally reconstructed radiographs(DRR) picture as the reference point, the center " 十 " points of verification films were measured, and the deviation at X,Y and Z axis were analyzed and compared. Results Statistical difference was found in the average deviation of the center point between the two groups Y and Z axis(P〈0.05), but not found on X axis(P〈0.05). Conclusions Compared with the vacuum bag, the fixed position of head-neck-shoulder mask in radiotherapy of thoracic tumor can reduce the setup error, improve the position accuracy, with simple and easy procedure, which is worthy of clinical promotion.
