Intermediate level dosimetry calculated on a volumetric dataset for intracavitary or intraluminal or endocavity applicators, for brachytherapy plans that have three‑dimensional image datasets acquired as part of simulation, if: (a) the planning process is required to deliver the prescribed dose to a three‑dimensional volume, and relative to multiple line for channel delivery applicators (excluding interstitial catheters and needles and multi‑catheter devices); and (b) based on review and assessment by a radiation oncologist, the planning process requires the differential of dose between target, organs at risk and normal tissue dose using avoidance strategies (which include placement of sources and/or dwell‑times or tissue packing); and (c) delineation of structures is required as part of the planning process to produce a dose‑volume histogram integral to the avoidance strategies; 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
