Megavoltage planning—level 3.2 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
