Abstract Background Helical Tomotherapy HT integrates linear accelerator and computerized tomography CT technology to deliver IMRT. Targets are localized i.e. outlined as gross tumor volume GTV and planning target volume PTV on the planning kVCT study while daily MVCT is used for correction of patient s set-up and assessment of inter-fraction anatomy changes. Based on dosimetric comparisons this study aims to find dosimetric equivalency between single fraction HT and Gamma Knife stereotactic
