Table 5. Comparison between GKRS and ABMP-SIDCA (Case 1).

Prescription: PTV D95%=100% dose (20 Gy), PTV= planned target volume, GTV=gross tumor volume, Vol.=volume

Cbll=cerebellar, Temp=temporal, Pariet=parietal, Front=frontal, rt=right, lt=left, v.=vermis

*In GK, non-intentional margin is added to cover the whole tumor included in the prescription isodose.
