title: The impact of peak-kilovoltage settings on heterogeneity-corrected photon-beam treatment plans.
abstract: Differences were evaluated in external-beam treatment plan dose calculations that result from the use of different Hounsfield-unit to electron-density conversion curves with CT images acquired with various tube potentials. These differences were found to be clinically insignificant and it was concluded that the impact of CT tube potential on treatment planning is negligible.
