中文摘要:
      目的 探讨用网膜体位固定技术进行腹盆部肿瘤三维适形放疗(3D-CRT)的临床应用价值。方法 11例腹盆部肿瘤病人采用拓能网膜体位固定技术完成3D-CRT。通过对患者CT扫描前、后摆位复位验证片以及CT模拟(CT-sim)后射野证实片与计划数字影像重建DRR图上的相关点的移动情况的测量比较,探讨采用网膜体位固定技术完成3D-CRT过程的误差源及误差范围。结果 实验结果和误差分析表明用网膜体位固定技术完成腹盆部肿瘤3D-CRT过程不确定度小于5mm。结论 网膜体位固定技术在腹盆部肿瘤3D-CRT中应用是切实可行的。
英文摘要:
      Objective To evaluate the clinical application value of positioning immobility technique by thermpolastic sheet for the three-dimension comformal radiation therapy(3D-CRT) of the abdominal and pelvic tumors.Methods Eleven patients were immobilized with Topslane thermoplastic sheet to carry out the 3D-CRT.The field movements were measured and compared between before and after the set-up.Results The inaccuracy of the process of 3D-CRT immobilized with Topslane thermoplastic sheet was within 5 mm.Conclusion Positioning immobility technique by thermoplastic sheet is useful and practical for 3D-CRT of the abdominal and pelvic tumors.
