                                                      Complex intensity modulated radiation therapy (IMRT) simulation and dosimetry for treatment planning, if
                                                      (a) all of the following apply in relation to the simulation:
                                                      (i) treatment set‑up and technique specifications are in preparation for multiple‑dose level IMRT planning or single‑dose level IMRT planning requiring motion management;
                                                      (ii) patient set‑up and immobilisation techniques are suitable for image volume data acquisition and reproducible IMRT treatment;
                                                      (iii) a high‑quality three‑dimensional or four‑dimensional volume dataset is acquired in treatment position for the relevant region of interest to be planned and treated with image verification; and
                                                      (b) all of the following apply in relation to the dosimetry:
                                                      (i) the IMRT planning process is required to calculate dose to multiple‑dose level volume structures or single‑dose level volume structures (including structures moving with physiologic processes or requiring precise positioning with respect to beam edges) and requires a dose‑volume histogram to complete the planning process;
                                                      (ii) based on review and assessment by a radiation oncologist, the IMRT planning process optimises the differential between target dose, organs at risk and normal tissue dose;
                                                      (iii) all relevant gross tumour targets, clinical target volumes, planning target volumes, internal target volumes and organs at risk are rendered and nominated with planning dose objectives;
                                                      (iv) organs at risk are nominated as planning dose constraints;
                                                      (v) dose calculations and dose‑volume histograms are generated in an inverse planned process using a specialised algorithm, with prescription and plan details approved and recorded with the plan;
                                                      (vi) a three‑dimensional or four‑dimensional image volume dataset is used for the relevant region to be planned and treated, with image verification for a multiple‑dose level IMRT planning or single‑dose level IMRT planning requiring motion management
                                                      Applicable once per course of treatment
