Published in 2017 at "Acta Oncologica"

DOI: 10.1080/0284186x.2017.1354131

Abstract: Abstract Background: Organ motion during radiation therapy with scanned protons leads to deviations between the planned and the delivered physical dose. Using a constant relative biological effectiveness (RBE) of 1.1 linearly maps these deviations into… read more here.

Published in 2020 at "Physics in medicine and biology"

DOI: 10.1088/1361-6560/abc12d

Abstract: IntroductionA constant relative biological effectiveness (RBE) of 1.1 is currently used in clinical proton therapy. However, the RBE varies with factors such as dose level, linear energy transfer (LET) and tissue type. Multiple RBE models… read more here.
