Introduction on Dose Optimisation

While the determination of D from Ψ , the solution of the so-called forward problem , is always possible, the inverse problem , i.e. determination of Ψ for a specified D is not always possible. The forward problem is the dose calculation problem for which a unique solution exists. {Ψ*}, {D*} : all possible

{Ψ}, {D} : physically possible (feasible)
