简化调强(simplified intensity modulated radiation therapy,sIMRT)技术是调强放射治疗(intensity modulated radiation therapy﹐IMRT)的一种简化模式﹐在临床应用中发挥着非常重要的作用。它具有自己的特点和适用范围。本文综述是基于简化调强技术与三维适形﹑调强放疗等技术的剂量学对比以及在肿瘤治疗中联合其它治疗手段的应用情况﹐旨在证实sIMRT是一种具备应用广泛﹑简易可行﹑性价比高和时效性好等特点的放疗技术﹐为其在临床应用中提供必要的选择依据。“,”The simplified intensity modulated radiation therapy (sIMRT) is a simplified model of intensity modulated radiation therapy(IMRT),which plays an important role in the course of tumor radiotherapy. sIMRT has its own chacateristics and clinical applicability. In this literature review,we mainly gave the contrast analysis of the dosimetry characteristics among those radiotherapy techniques (3DCRT、sIMRT、IMRT,etc) and the clinical application while sIMRT combined with other therapies, finally, aims to confirm that sIMRT features widely used、simple and feasible、high ratio of performance-to-cost benefit and good timeliness, besides, providing the necessary basis for clinical application.
