The SPR of water to the RGD was calculated by Monte Carlo simulation, and $\\varepsilon _{{\\rm LET}}^{{\\rm RGD}}$ was investigated experimentally using a 70 MeV proton beam. For clinical usage, the residual range R res was used as a quality index to determine the correction factor for the beam quality $k_{{\\rm Q},{{{\\rm Q}}_{0}}}^{{\\rm RGD}}$ and the LET quenching effect of the RGD $k_{{\\rm LET}}^{{\\rm RGD}}$ . The proposed method was evaluated by measuring D w at different depths in a 200 MeV proton beam.\n\\nFor both non-modulated and modulated proton beams, $k_{{\\rm Q},{{{\\rm Q}}_{0}}}^{{\\rm RGD}}$ decreases rapidly where R res is less than 4 cm. The difference in $k_{{\\rm Q},{{{\\rm Q}}_{0}}}^{{\\rm RGD}}$ between a non-modulated and a modulated proton beam is less than 0.5% for the R res range from 0 cm to 22 cm. $\\varepsilon _{{\\rm LET}}^{{\\rm RGD}}$ decreases rapidly at a LET range from 1 to 2 keV µm−1. In the evaluation experiments, D w using RGDs, $D_{{\\rm w},{\\rm Q}}^{{\\rm RGD}}$ showed good agreement with that obtained using an ionization chamber and the relative difference was within 3% where R res was larger than 1 cm. The uncertainty budget for $D_{{\\rm w},{\\rm Q}}^{{\\rm RGD}}$ in a proton beam was estimated to investigate the potential of RGD postal dosimetry in proton therapy.\n\\nThese results demonstrate the feasibility of RGD dosimetry in a therapeutic proton beam and the general versatility of the proposed method. In conclusion, the proposed methodology for RGDs in proton dosimetry is applicable where R res  >  1 cm and the RGD is feasible as a postal audit dosimeter for proton therapy.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1361-6560/aa9155","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://iopscience.iop.org/article/10.1088/1361-6560/aa9155"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://iopscience.iop.org/article/10.1088/1361-6560/aa9155","subitem_relation_type_select":"URI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"張, 維珊"}],"nameIdentifiers":[{"nameIdentifier":"491468","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古場, 裕介"}],"nameIdentifiers":[{"nameIdentifier":"491469","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katayose, Tetsurou"}],"nameIdentifiers":[{"nameIdentifier":"491470","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasui, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"491471","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Omachi, Chihiro"}],"nameIdentifiers":[{"nameIdentifier":"491472","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hariu, Masatsugu"}],"nameIdentifiers":[{"nameIdentifier":"491473","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saitoh, Hedetoshi"}],"nameIdentifiers":[{"nameIdentifier":"491474","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 維珊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491475","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古場 裕介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"491476","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Correction of stopping power and LET quenching for radiophotoluminescent glass dosimetry in a therapeutic proton beam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Correction of stopping power and LET quenching for radiophotoluminescent glass dosimetry in a therapeutic proton beam"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-24"},"publish_date":"2018-04-24","publish_status":"0","recid":"48801","relation_version_is_last":true,"title":["Correction of stopping power and LET quenching for radiophotoluminescent glass dosimetry in a therapeutic proton beam"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:24:10.434615+00:00"}
