Planning aims

Dose normalization Prescription dose (D pr

) to %volume of PTV

95% of PTV should be covered by D pr 99% of PTV should receive ≥ 90% of D pr Common prescription levels: 65-85% isodoseline

High dose constraints Dose > 105% of D pr

must be inside PTV

D max

< 125-140% of D pr

Features of SABR

Dose calculation: type B algorithm is advised (especially lung)
