调强放射治疗剂量验证研究进展

Verification of the dose distribution of IMRT plan

调强放射治疗(IMRT)以其较好的靶区剂量分布和保护正常组织等特点已在国内多家医疗单位开展。但是由于此项治疗技术受到诸如影像、逆向计划设计、精确定位及治疗设备等因素的影响,对于治疗方案的剂量验证显得尤为重要。现对近年来世界多个国家的肿瘤组织关于 IMRT 计划剂量验证方面的研究作一综述。

Intensity modulated radiation therapy was used by many countries because of fine dose dis- tribution of GTV and better protection of normal tissue.The result of IMRT is affected by many factors such as imaging,designing of contrary,plan,exact position of GTV and equipments,so it is very important to verify the dose distribution about treatment plan.This article is a summary about the studies on verification of IMRT which has been done by many tumor organizations in difference countries.
