摘要: 肺组织是并联器官,属于放射敏感器官,在胸部放疗时需要严格控制正常肺组织的受量。本文通过用两种正常肺组织的不同定义勾画后得到的DVH图有关数据进行比较分析发现,肺内大体积肿瘤时,定义正常肺组织时应减去肿瘤体积,以期指导正常肺组织的勾画,更客观反映功能性肺组织的受量,更精确的预测肺损伤。

关键词: 肺肿瘤, 调强放射治疗, 正常肺组织

Abstract: The lung is a parallel organ,which is radiation sensitive. It is necessary to strictly control the dose to normal lung tissue during chest radiotherapy. By comparing and analyzing the DVH map data obtained after the definition of two different lung ttissue, it is found that when a large tumor in the lung is defined, the tumor volume should be subtracted from the definition of normal lung tissue in order to more objectively reflect the functional lung ttissue intake and guide the delineation of normal lung tissue, so that lung injury can be predicted more accurately.

Key words: Lung tumor, Intensity-modulated radiation therapy, Normal lung tissue
