ESTRO course Dose Modelling and Verification 2017

A feasible energy fluence engine should

• be simple enough to understand the behaviour of the model

• have only a small number of free parameters

• the model parameters should be determined by measurements that are not too complicated and time consuming i.e. output factors, profiles or depth dose curves in water and air • be complex enough to confirm all measurements in agreement with the accuracy demands • fast in sampling the particle properties (if used for Monte Carlo dose engines)
