ESTRO course Dose Modelling and Verification 2017

Monte Carlo Modelling: Conclusions

• As the distance from the field edge increased so too did the number of low energy photons incident out-of-field

– Implications for detector choice

– Radiobiological Effectiveness

• The ZLAST plots indicate that modelling the peripheral components of the linac head would most likely have a negligible contribution to out-of-field dose
