	abstract = {Background: To compare helical tomotherapy (HT) with X-knife stereotactic body radiation therapy (HT-SBRT/X-SBRT) for primary or metastatic lung cancer regarding planning target volume (PTV) coverage, such as homogeneity index (HI), conformity index (CI) and dose-volume histogram (DVH) of organs at risk (OARs). 
Methods: We retrospectively analyzed 21 patients receiving definitive radiation treatment for non-small cell lung cancer (NSCLC) or pulmonary metastases at our institution between March 2015 and October 2016. Tumors were irradiated with 4–10 Gy per fraction in 5–15 fractions. Plans were compared according to PTV coverage and OARs sparing. 
Results: Significant differences between HT and X-knife were observed for both HI (P=0.003) and CI (P},
