We investigated three sites: prostate (three cases), head and neck (three cases), and pleura (two cases). We used the total MU and the MU weighted average of segment area (MWSA) in each plan to compare VMAT and IMRT plans. VMAT plans tended to have a larger MWSA and a lower total MU than did IMRT plans in all sites, although there was little difference between dose indices in either irradiation technique. We conclude that VMAT is a better treatment technique due to its higher MU efficiency caused by the larger segment area.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s12194-012-0164-3","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://link.springer.com/article/10.1007%2Fs12194-012-0164-3"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://link.springer.com/article/10.1007%2Fs12194-012-0164-3","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1865-0333","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":"Kawashima, Motohiro"}],"nameIdentifiers":[{"nameIdentifier":"463525","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, Shuichi"}],"nameIdentifiers":[{"nameIdentifier":"463526","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Haga, Akihiro"}],"nameIdentifiers":[{"nameIdentifier":"463527","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakumi, Akira"}],"nameIdentifiers":[{"nameIdentifier":"463528","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurokawa, Chie"}],"nameIdentifiers":[{"nameIdentifier":"463529","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugimoto, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"463530","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Karasawa, Kumiko"}],"nameIdentifiers":[{"nameIdentifier":"463531","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakagawa, Keiichi"}],"nameIdentifiers":[{"nameIdentifier":"463532","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasai, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"463533","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川嶋 基敬","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463534","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"唐澤 久美子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463535","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":"Comparison of total MU and segment areas in VMAT and step-and-shoot IMRT plans","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Comparison of total MU and segment areas in VMAT and step-and-shoot IMRT plans"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-03-29"},"publish_date":"2013-03-29","publish_status":"0","recid":"46514","relation_version_is_last":true,"title":["Comparison of total MU and segment areas in VMAT and step-and-shoot IMRT plans"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:50:51.821043+00:00"}
