At the same time that CT data was acquired, the\nrespiratory signal of the patient and the X-ray on/off signal on CT scanner were recorded. Each CT image was\ntimed according to the phase of respiration waveform. Conversion of the CT number to the water equivalent path\nlength (WEL) was performed with our treatment planning system that included a conversion table. As an\nillustration, the CT images of a patient with liver cancer at the right upper lobe were analyzed. The geometric\nsize of the liver and WELs from body surface to isocenter were measured in each CT image.\nResults: Variations of WEL from body surface to isocenter at the anterior-posterior and posterior-anterior\ndirection were 6.2 mm and 18.9 mm, respectively. Liver size changed by 35.2 mm. However, these variations were\nshown to be considerably reduced by gated irradiation.\nConclusion: A method using sequential CT images with respiration waveform was proposed. It appeared to be\nuseful in evaluating the uncertainties of the range calculation associated with patient breathing.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0360-3016","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":"Minohara, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"428559","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Endo, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"428560","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanai, Tatsuaki"}],"nameIdentifiers":[{"nameIdentifier":"428561","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katou, Hirotoshi"}],"nameIdentifiers":[{"nameIdentifier":"428562","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Hirohiko"}],"nameIdentifiers":[{"nameIdentifier":"428563","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"蓑原 伸一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"428564","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"遠藤 真広","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"428565","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金井 達明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"428566","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤 博敏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"428567","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻井 博彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"428568","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":"Estimating Uncertainties of the Geometrical Range of particle Radiotherapy during Respiration","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimating Uncertainties of the Geometrical Range of particle Radiotherapy during Respiration"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-04-15"},"publish_date":"2003-04-15","publish_status":"0","recid":"43069","relation_version_is_last":true,"title":["Estimating Uncertainties of the Geometrical Range of particle Radiotherapy during Respiration"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:31:38.206198+00:00"}
