In this study, we attempted to develop a method to estimate linear energy transfer (LET) for a treatment planning system that only handled physical and RBE-weighted doses. The LET taken from a database of clinical broad beams was related to the RBE per energy with two polyline fitting functions for spread-out Bragg peak (SOBP) and for entrance depths, which would be selected by RBE threshold per energy per modulation. The LET estimation was consistent with the original calculation typically within a few keV/$\\mu$m except for the overkill at the distal end of SOBP.\nThe CIRT treatments can thus be related to the knowledge obtained in radiobiology experiments that used LET to represent radiation quality.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"World Congress on Medical Physics & Biomedical Engineering","subitem_description_type":"Other"}]},"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":"Kanematsu, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"717367","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsufuji, Naruhiro"}],"nameIdentifiers":[{"nameIdentifier":"717368","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku"}],"nameIdentifiers":[{"nameIdentifier":"717369","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼松 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717370","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松藤 成弘","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717371","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭 拓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717372","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Estimation of linear energy transfer distribution for broad-beam carbon-ion radiotherapy at the National Institute of Radiological Sciences, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of linear energy transfer distribution for broad-beam carbon-ion radiotherapy at the National Institute of Radiological Sciences, Japan"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-06-11"},"publish_date":"2018-06-11","publish_status":"0","recid":"72816","relation_version_is_last":true,"title":["Estimation of linear energy transfer distribution for broad-beam carbon-ion radiotherapy at the National Institute of Radiological Sciences, Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:35:45.316268+00:00"}
