The dosimeter response was simulated according to an experimental quenching model. The beam model followed a treatment planning system. The beam was decomposed into finely arranged beamlets with weights estimated by deconvolution of longitudinal dosimeter responses. The distributions of physical and biological doses were reconstructed from the estimated weights and were compared with the plan. We also evaluated the sensitivity to measurement errors and to erratic delivery with an undelivered beamlet.\nResults: The reconstructed physical and biological doses accurately reproduced the simulated delivery with errors approximately corresponding to the measurement errors. The erratic beam delivery was easily detectable by comparison of biological dose distribution to the plan.\nConclusions: We have developed a method to measure physical and biological doses by longitudinal dosimetry of quenched response without using plan data. The method only involves a general optimization algorithm, a radiobiology model, and experimental beamlet data, and requires no extra corrections. Theoretically, this approach is applicable to various dosimeters and to proton and ion beams of any delivery method, regardless of quenching or biological effectiveness.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":" Wiley Periodicals, Inc."}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"30589441","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/mp.13360","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/10.1002/mp.13360","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0094-2405","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":"Kanematsu, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"752997","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku"}],"nameIdentifiers":[{"nameIdentifier":"752998","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yonai, Shunsuke"}],"nameIdentifiers":[{"nameIdentifier":"752999","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"753000","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanematsu, Nobuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"753001","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"753002","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yonai, Shunsuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"753003","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, Hideyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"753004","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":"Technical Note: Reconstruction of physical and biological dose distributions of carbon‐ion beam through deconvolution of longitudinal dosimeter responses","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Technical Note: Reconstruction of physical and biological dose distributions of carbon‐ion beam through deconvolution of longitudinal dosimeter responses"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-12-28"},"publish_date":"2018-12-28","publish_status":"0","recid":"74753","relation_version_is_last":true,"title":["Technical Note: Reconstruction of physical and biological dose distributions of carbon‐ion beam through deconvolution of longitudinal dosimeter responses"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:53:20.836806+00:00"}
