We have installed an X-ray fluoroscopic imaging system in our treatment room for clinical use with an amplitude-based gating strategy. We evaluated the effects of this gating under realistic organ motion conditions using 4 DCT data of lung and liver tumors. 4 DCT imaging was done for 24 lung and liver patients using the area-detector CT. We calculated the field-specific target volume (FTV) for the gating window, which was defined for a single respiratory cycle. Prescribed doses of 48 Gy relative biological effectiveness (RBE)/fraction/four fields and 45 Gy RBE/two fractions/two fields were delivered to the FTVs for lung and liver treatments, respectively. Dose distributions were calculated for the repeated first respiratory cycle (= planning dose) and the whole respiratory data (= treatment dose). We applied eight phase-controlled rescannings with the amplitude-based gating. For the lung cases, D95 of the treatment dose (= 96.0 ± 1.0%) was almost the same as that of the planning dose (= 96.6 ± 0.9%). D(max)/D(min) of the treatment dose (= 104.5 ± 2.2%/89.4 ± 2.6%) was slightly increased over that of the planning dose (= 102.1 ± 1.0%/89.8 ± 2.5%) due to hot spots. For the liver cases, D95 of the treatment dose (= 97.6 ± 0.5%) was decreased by ∼ 1% when compared with the planning dose (= 98.5 ± 0.4%). D(max)/D(min) of the treatment dose was degraded by 3.0%/0.4% compared with the planning dose. Average treatment times were extended by 46.5 s and 65.9 s from those of the planning dose for lung and liver cases, respectively. As with regular respiratory patterns, amplitude-based gated multiple phase-controlled rescanning preserves target coverage to a moving target under irregular respiratory patterns.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Oxford University Press"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"24835238","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1093/jrr/rru032","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0449-3060","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":"Mori, Shinichiro"}],"nameIdentifiers":[{"nameIdentifier":"469739","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku"}],"nameIdentifiers":[{"nameIdentifier":"469740","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Furukawa, Takuji"}],"nameIdentifiers":[{"nameIdentifier":"469741","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Wataru"}],"nameIdentifiers":[{"nameIdentifier":"469742","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Mio"}],"nameIdentifiers":[{"nameIdentifier":"469743","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shirai, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"469744","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noda, Koji"}],"nameIdentifiers":[{"nameIdentifier":"469745","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"469746","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Naoyoshi"}],"nameIdentifiers":[{"nameIdentifier":"469747","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 慎一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469748","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭 拓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469749","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古川 卓司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469750","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 渉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469751","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中嶋 美緒","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469752","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"白井 敏之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469753","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野田 耕司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469754","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安田 茂雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469755","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本 直敬","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"469756","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":"Amplitude-based gated phase-controlled rescanning in carbon-ion scanning beam treatment planning under irregular breathing conditions using lung and liver 4DCTs.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Amplitude-based gated phase-controlled rescanning in carbon-ion scanning beam treatment planning under irregular breathing conditions using lung and liver 4DCTs."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-19"},"publish_date":"2015-03-19","publish_status":"0","recid":"47044","relation_version_is_last":true,"title":["Amplitude-based gated phase-controlled rescanning in carbon-ion scanning beam treatment planning under irregular breathing conditions using lung and liver 4DCTs."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:44:34.354949+00:00"}
