The radiation techniques for lung cancer stereotactic body radiotherapy (SBRT) include intensity modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT) and helical tomotherapy (HT).Concerning the target conformity and dosimetric homogeneity index, HT and VMAT technologies are superior to IMRT.On the contrary, HT and VMAT technology can increase low dose area irradiated of lung.Comparing to other two technologies, VMAT can obviously shorten the treatment time.At present, there is no consensus how to choose individually optimized radiotherapy technology for different location and stages lung tumors.
