Effects of modulation materials for lung dose distribution in proton therapy

This study created an easier approach and successfully created the spread–out Bragg peak (SOBP) in lung heterogeneous media, using statistically fitted matrix with uniformity of SOBP better than 2%. The weighting factors matrix for creating SOBP may theoretically be applied to any multiple range modulation systems. The methodology for the 150 MeV proton beams' range modulation in the lung heterogeneous media can be similarly applied to other energy of proton as well as for heavy ion therapy.
