  • per Apollo Wilson “SRS, 4D, SBRT, SART, can all be delivered via IMRT plans. In fact, in most cases, you would need an IMRT plan for these treatment modalities. Check the dose/fraction and number of fractions prescribed. If the dose is hypofractionated (>200 cGy/fx and < 6 fx), then it’s very likely that the treatment modality is SBRT (06). If the fraction size is standard (180 or 200 cGy/fx), then it is most likely IMRT, if mentioned.”
