                                                      Simple complexity radiation therapy simulation and dosimetry for treatment planning, with imaging for field setting, if:
                                                      (a) all of the following apply in relation to the simulation:
                                                      (i) treatment set‑up and technique specifications are in preparation for two‑dimensional radiation therapy dose planning;
                                                      (ii) patient set‑up and immobilisation techniques are suitable for two‑dimensional radiation therapy treatment where interfraction reproducibility is required;
                                                      (iii) imaging datasets are acquired for the relevant region of interest to be planned; and
                                                      (b) all of the following apply in relation to the dosimetry:
                                                      (i) the two‑dimensional planning process is required to calculate dose to a volume, however a dose‑volume histogram is not required to complete the planning process;
                                                      (ii) based on review and assessment by a radiation oncologist, the two‑dimensional planning process is not required to maximise the differential between target dose and normal tissue dose;
                                                      (iii) the target (which may include gross, clinical and planning targets as a composite structure or field border outline), as defined in the prescription, is rendered as a two‑dimensional structure as field borders or a volume;
                                                      (iv) organs at risk are delineated if required, and assessment of dose to these structures is derived from dose point calculations, rather than full calculation and inclusion in a dose‑volume histogram;
                                                      (v) dose calculations are calculated using a specialised algorithm, with prescription and plan details approved and recorded with the plan
                                                      Applicable once per course of treatment
