     60 patients with intracranial lesions treated with the first Leksell Gamma Knife Perfexion in China between July to September in 2011.
      Different treatment plans of Leksell GammaPlan version 9.0 were compared for target coverage, number of isocenters, doses of important structures.
     The software generated high dosimetric conformity and good protection for important structures.
     This was a retrospective study.
     The treatment plan of LGK PFX is efficient.
     Images merged with functional MRI improves to decrease high doses for important function area.
