For RPLD dose estimation, we used the ISO 22127 formalism. Additional unit-specific correction factors were introduced and determined via the measured data. For TomoTherapy (7 units) and CyberKnife (4 units), the doses were measured under machine-specific reference fields. For FFF linac (5 units), in addition to the reference condition, we obtained the field-size effects for the range from 5 × 5 cm to 25 × 25 cm. \nResults: The correction factors were estimated as 1.008 and 0.999 for TomoTherapy and CyberKnife, respectively. For FFF linac, they ranged from 1.011 to 0.988 for 6 MV and from 1.011 to 0.997 for 10 MV as a function of the side length of the square field from 5 to 25 cm. The estimated uncertainties of the absorbed dose to water measured by RPLD for the units were 1.32%, 1.35%, and 1.30% for TomoTherapy, CyberKnife, and FFF linac, respectively. A summary of the dosimetry audits of these treatment units using the obtained correction factors is also presented. The average percentage differences between the measured and hospital-stated doses were <1% under all conditions. \nConclusion: RPLD can be successfully used as a dosimetry audit tool for modern treatment units.\n","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"34214838","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ejmp.2021.06.010","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://www.sciencedirect.com/science/article/pii/S1120179721002301?via%3Dihub","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1120-1797","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":"Hideyuki, Mizuno"}],"nameIdentifiers":[{"nameIdentifier":"1015146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamashita, Wataru"}],"nameIdentifiers":[{"nameIdentifier":"1015147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okuyama, Hiroaki"}],"nameIdentifiers":[{"nameIdentifier":"1015148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takase, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"1015149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tohyama, Naoki"}],"nameIdentifiers":[{"nameIdentifier":"1015150","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimizu, Hidetoshi"}],"nameIdentifiers":[{"nameIdentifier":"1015151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujita, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"1015152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kito, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"1015153","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taku, Nakaji"}],"nameIdentifiers":[{"nameIdentifier":"1015154","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigekazu, Fukuda"}],"nameIdentifiers":[{"nameIdentifier":"1015155","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hideyuki, Mizuno","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015156","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taku, Nakaji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigekazu, Fukuda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015158","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":"Dose response of a radiophotoluminescent glass dosimeter for TomoTherapy, CyberKnife, and flattening-filter-free linear accelerator output measurements in dosimetry audit","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dose response of a radiophotoluminescent glass dosimeter for TomoTherapy, CyberKnife, and flattening-filter-free linear accelerator output measurements in dosimetry audit"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-07-29"},"publish_date":"2021-07-29","publish_status":"0","recid":"84055","relation_version_is_last":true,"title":["Dose response of a radiophotoluminescent glass dosimeter for TomoTherapy, CyberKnife, and flattening-filter-free linear accelerator output measurements in dosimetry audit"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:44:22.018758+00:00"}
