Dose Course 2018_Flipping book

A feasible energy fluence engine should

• be simple enough so one can understand the behaviour of the model

• have a small number of free parameters

• enable model parameters to be determined from manageable data sources of measurements (output factors, profiles or depth dose curves in water and air) and geometry (linac head design) • be complex enough to confirm all measurements in agreement with the accuracy demands
