Quote from dineshsaroj on December 9, 2025, 5:55 pmI have simulated the varian truebeam 6 FFF linac I have validated it with linac by comparing relative measurement using PRIMO. When I simulate the SBRT plan ,there is difference in structure volume from TPS to Primo and dose is primo is 2times the dose from TPS. Does anyone know what could be the reason?

Yes I have performed the dose calibration.
