The respiratory\nperiod was subdivided into 10 phases and\nintrafractional tumor motions were evaluated by\nidentifying the center of mass of gross tumor volume\n(GTV) for each respiratory phase.\nThe mean ranges of the tumor motion over 10 patients\nwere 1.4 mm, 2.2 mm and 6.6 mm in left-right (LR),\nanterior-posterior (AP) and superior-inferior (SI)\ndirections, respectively. A previous work which studied\nthe lung tumor motion for freely breathing patients\nwithout immobilization by using 4DCT have reported\nthat the movement averaged 1.9mm, 4.0mm and 10.3\nmm in LR, AP and SI-directions, respectively. The\nimmobilization reduces the range of the lung tumor\nmotion by 0.5mm, 1.8mm and 3.7mm in each direction.\nThis result shows that immobilization is effective not\nonly for fixing patients to a couch, but also for reducing\nintrafractional tumor motion.","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":"H20年度HIMAC共同利用研究成果発表会","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":"馬場, 雅行"}],"nameIdentifiers":[{"nameIdentifier":"633541","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"蓑原, 伸一"}],"nameIdentifiers":[{"nameIdentifier":"633542","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"土橋, 卓"}],"nameIdentifiers":[{"nameIdentifier":"633543","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森, 慎一郎"}],"nameIdentifiers":[{"nameIdentifier":"633544","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊谷, 始紀"}],"nameIdentifiers":[{"nameIdentifier":"633545","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭, 拓"}],"nameIdentifiers":[{"nameIdentifier":"633546","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中嶋, 美緒"}],"nameIdentifiers":[{"nameIdentifier":"633547","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本, 直敬"}],"nameIdentifiers":[{"nameIdentifier":"633548","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"須金, 紀雄"}],"nameIdentifiers":[{"nameIdentifier":"633549","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神立, 進"}],"nameIdentifiers":[{"nameIdentifier":"633550","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"馬場 雅行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633551","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"蓑原 伸一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633552","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"土橋 卓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633553","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 慎一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633554","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊谷 始紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633555","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭 拓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633556","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中嶋 美緒","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633557","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本 直敬","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633558","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"須金 紀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633559","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神立 進","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633560","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"中心型肺癌に対する炭素イオン線治療における3次元治療計画の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中心型肺癌に対する炭素イオン線治療における3次元治療計画の研究"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-14"},"publish_date":"2011-03-14","publish_status":"0","recid":"64240","relation_version_is_last":true,"title":["中心型肺癌に対する炭素イオン線治療における3次元治療計画の研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:13:52.505486+00:00"}
