Abstract Background Helical Tomotherapy HT integrates linear accelerator and computerized tomography CT technology to deliver IMRT. Targets are localized . 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
