摘　　要：目的 探索是适形调强放射治疗(Intensity Modulation Radiation Therapy)技术在鼻腔筛窦癌放疗的临床应用。方法 对2001年4月～2002年5月在我院利用NOMOS公司的孔雀系统实施放疗的鼻腔筛窦癌病人作分析。结果 靶区剂量剖面图显示射野形状和剂量分布形状从三维方向上充分与肿瘤靶区的截面形状相适形,而邻近的重要器官(如晶体、视神经、垂体)的剂量与靶区剂量相差明显。DVH图。结论 IMRT具有明显的剂量分布优势,不但给予肿瘤高剂量放疗,而且避免器官的放射性损伤。Objective To explore the clinical use of intensity modulation therapy for naso-ethmoid sinus. Methods The patients with such cancers treated from April 2001 to May 2001 received radiotherapy by Deacock system of NOMOS Company. Result The target dose section chart showed the shapes of fields and dose distribution were suitable for the tumor targets in 30 and the shapes of nearby important organs (eg. Crystal, optic nerve, pituitary) were very different from the targets Conclu-sion IMRT has great dose-distribution superiority for offering the famous with a high dose and avoiding radioactive injury of the important organ.
