The scheme of fabricated polymethyl-methacrylate (PMMA) new phantom. a, a certain variable; L, length of PMMA phantom’s slope; H, height of PMMA phantom; W, width of PMMA phantom.|@|~(^,^)~|@|The setup of fabricated new phantom for ocular treatment within 2nd check; depth and dose. (a) Measurement of range with EBT3 film, (b) confirmation of dose using ionization chamber.|@|~(^,^)~|@|The energy dependence results of depth dose profiles at Bragg peaks. (a) Bragg peak of 46.0 MeV, (b) Bragg peak of 32.0 MeV.|@|~(^,^)~|@|The Comparison depth dose profiles between EBT3 film and water. (a) Represents the same value of beam range and SOBP, full modulation case, (b) general case of proton therapy for ocular tumors. SOBP, spread-out Bragg peak.|@|~(^,^)~|@|The EBT3 film analysis ocular tumor data which depend on proton energy. EBT3 film data (a) 57.7 MeV, (b) 46.0 MeV, and (c) 32.0 MeV. Depth dose profiles (d) 57.7 MeV, (e) 46.0 MeV, and (f) 32.0 MeV, and lateral profilers from EBT3 film (g) 57.7 MeV, (h) 46.0 MeV, and (i) 32.0 MeV.|@|~(^,^)~|@|The depth dose profiles with TOPAS, EBT3 film and MLIC. TOPAS, tool for particle simulation; MLIC, multilayer ionization chamber.
