The revised method deals with 11 representative tissues with specific elemental composition and density, based on a latest compilation of standard tissue data. We report here how the revision was actually implemented into clinical practice. We applied the revised method to 7 CT-scanning conditions currently in use for treatment planning. For each condition, we derived CT numbers and stopping-power ratios of the representative tissues to constitute a polyline conversion function. We analyzed the target-depth change by the revision for 38 beams in treatment plans for 13 randomly sampled patients. The revision caused a mean change of +0.3 mm with a standard deviation of 0.4 mm. The maximum change was +1.2 mm or +0.5% of the depth, which may be clinically insignificant. The transition to the revised method was straightforward and would slightly improve the accuracy of beam range in particle therapy.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本医学物理学会"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"28924096","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11323/jjmp.37.1_34","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":"https://doi.org/10.11323/jjmp.37.1_34"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.11323/jjmp.37.1_34","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1345-5354","subitem_source_identifier_type":"ISSN"}]},"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":"兼松, 伸幸"}],"nameIdentifiers":[{"nameIdentifier":"485928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森, 慎一郎"}],"nameIdentifiers":[{"nameIdentifier":"485929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭, 拓"}],"nameIdentifiers":[{"nameIdentifier":"485930","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼松 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485931","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 慎一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485932","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭 拓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485933","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"粒子線治療計画のためのCT値阻止能比変換の校正方法の更新","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"粒子線治療計画のためのCT値阻止能比変換の校正方法の更新"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-06"},"publish_date":"2017-10-06","publish_status":"0","recid":"48351","relation_version_is_last":true,"title":["粒子線治療計画のためのCT値阻止能比変換の校正方法の更新"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:29:06.427269+00:00"}
