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.
