Megavoltage planning—level 4 Stereotactic body radiation therapy (SBRT) 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 inverse planning with multiple non-coplanar, rotational or fixed beam stereotactic delivery or intensity modulated radiation therapy (IMRT) stereotactic delivery; (ii) personalised patient set-up and immobilisation techniques are suitable for reliable imaging acquisition and reproducible, including techniques to minimise motion of organs at risk and targets; (iii) small-field and ablative treatment is used; (iv) a high-quality three-dimensional or four-dimensional image volume dataset is acquired in treatment position for the relevant region of interest to be planned, treated and verified (through daily planar or volumetric image guidance strategies); and (b) all of the following apply in relation to the dosimetry: (i) the planning process is required to calculate dose to single or multiple target structures and requires a dose-volume histogram to complete the planning process; (ii) based on review and assessment by a radiation oncologist, the planning process maximises the differential between target dose, organs at risk and normal tissue dose; (iii) all relevant gross tumour volumes, clinical target volumes, planning 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 using a validated stereotactic-type algorithm, with prescription and plan details approved and recorded with the plan Applicable once per course of treatment
