Complex level dosimetry for brachytherapy plans that contain multiple needles, catheters or radiation sources, calculated on the three‑dimensional volumetric dataset, if: (a) the planning process is required to deliver a prescribed dose to a target volume relative to multiple channel delivery applicators, needles or catheters or radiation sources; and (b) based on review and assessment by a radiation oncologist, the planning process requires the differential of doses between the target, organs at risk and normal tissue dose using avoidance strategies (which include the placement of sources and/or dwell times or tissue packing; and (c) delineation of structures is required as part of the planning process, in order to produce a dose‑volume histogram to review and assess the plan; and (d) dose calculations are performed on a personalised basis, which must include three‑dimensional dose calculation to target and organ at risk volumes; and (e) dose calculations and the dose‑volume histogram are approved and recorded with the plan
