放射治疗是非小细胞肺癌(non-small cell lung cancer,NSCLC)的主要治疗手段之一,60%以上的NSCLC患者在其治疗的不同时期需要接受放疗。NSCLC放射治疗的目的是最大限度地减少放射性肺损伤,并在确保患者生存质量的前提下,控制局部肿瘤生长、延长患者生存时间或达到治愈,因此,理想的放射治疗是在给予肿瘤高剂量照射的同时,最大限度地保护周围正常的肺组织,这就需要准确
Radiation therapy is one of the main treatments for non-small cell lung cancer (NSCLC). More than 60% of patients with NSCLC require radiotherapy at different stages of their treatment. The purpose of NSCLC radiation therapy is to minimize radiation-induced lung injury, and to control the local tumor growth and prolong the survival time of patients or to achieve the cure under the premise of ensuring the quality of life of the patients. Therefore, the ideal radiation therapy is to give high- At the same time, to maximize the protection of normal lung tissue around, which needs accurate
