Definitive radiotherapy for oropharyngeal cancer (OPC) requires adequate PTV coverage, but the optimal degree of target coverage is unknown. Some protocols require a PTVD95≥95% whereas others require PTVD95≥100% of prescription dose. Prescribing higher PTV do...

To characterize the dependence of relative electron density (RED) to Hounsfield unit (HU) calibration accuracy on acquisition and reconstruction settings on the Varian Ethos HyperSight CBCT to assess implications for adaptive radiotherapy dose calculation.
