Radiotherapy dose calculation is typically based on a computed tomography (CT) scan and requires a conversion of CT numbers to the relevant physical parameter, mass density (MD) or relative electron density (RED) for photon therapy, and stopping-power ratio (...

Stopping-power ratio (SPR) uncertainty in proton therapy is typically estimated from computed tomography (CT) scans of adult-sized phantoms and applied to adult and pediatric patients. Adult uncertainties may not represent pediatric patients due to difference...
