The microscopic fine structures of the device may enlarge the Bragg-peak width of the beam as compared to the non-porous solid materials with the same water-equivalent thickness. In this study, we investigate this Bragg-peak degradation effect on patient dose distributions in scanned carbon-ion, World Congress on Medical Physics and Biomedical Engineering 2018 (IUPESM2018)}, title = {Bragg-peak degradation of a carbon-ion beam penetrating a patient immobilization device with microscopic fine structures}, year = {2018} }
