Carbon-12 beams having the energy of 241.5 MeV/u were irradiated on a polyethylene target. The target had a square-prism-shaped cavity in it. The thickness of the cavity was changed from 3.0 to 0.0 cm with 0.3-cm steps. For each setup of the cavity, 7.5 × 10^10 carbon ions were irradiated. A pinhole-type X-ray camera was placed beside the target and utilized to acquire the beam images. The beam trajectory and a gap on the trajectory clearly appeared in the acquired images. The actual beam shifts well coincided with the estimated beam shifts from the acquired images. The maximum fluctuation of the estimated shifts was approximately 0.2 cm. It was confirmed that the internal cavity can be imaged and the range can be accurately evaluated.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.35848/1347-4065/aba22a","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.35848/1347-4065/aba22a","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4922","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":"Yamaguchi, Mitsutaka"}],"nameIdentifiers":[{"nameIdentifier":"879476","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Seiichi, Yamamoto (Nagoya Univ.)"}],"nameIdentifiers":[{"nameIdentifier":"879477","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maki, Kitano (Nagoya Univ.)"}],"nameIdentifiers":[{"nameIdentifier":"879478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshiki, Kubota (Gunma Univ.)"}],"nameIdentifiers":[{"nameIdentifier":"879479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"879480","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takashi, Akagi (Hyogo Ion Beam Medical Center)"}],"nameIdentifiers":[{"nameIdentifier":"879481","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagao, Yuuto"}],"nameIdentifiers":[{"nameIdentifier":"879482","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawachi, Naoki"}],"nameIdentifiers":[{"nameIdentifier":"879483","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Mitsutaka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"879484","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"879485","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagao, Yuuto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"879486","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawachi, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"879487","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":"Estimation of shifts of therapeutic carbon-ion beams owing to cavities in a polyethylene target by measuring prompt X-ray images","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of shifts of therapeutic carbon-ion beams owing to cavities in a polyethylene target by measuring prompt X-ray images"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-02"},"publish_date":"2020-07-02","publish_status":"0","recid":"80150","relation_version_is_last":true,"title":["Estimation of shifts of therapeutic carbon-ion beams owing to cavities in a polyethylene target by measuring prompt X-ray images"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:42:26.483615+00:00"}
