In order to estiate the dose at the center of SOBP by the calculation, it is necessary to estimate the field size dependence accuracy. We have developed the dose estimation method using a semi-empirical dose distribution of pencil beam which take into account of the effect of large-angle scattering fragment particles. The obtained field-size dependencies of the therapeutic carbon beam agreed with the measured dependencies very well.}, pages = {55--56}, title = {炭素線治療における線量推定法の開発}, year = {2007} }
