Patient doses were measured with small sized - less than 7mm wide - silicon-photodiode dosimeters, 34 in number, which were implanted at various tissue and organ positions within adult and 6-year-child anthropomorphic phantoms.  Output signals from photodiode dosimeters were read out on a personal computer, from which organ and effective doses were computed.  For the adult phantom, organ doses for organs within scan range and effective doses were 8-35 mGy and 7-18 mSv in chest CT, and 12-33 mGy and 10-21 mSv in abdominopelvic CT.  For the paediatric phantom, these were 4-17 mGy and 3-7 mSv in chest CT, and 5-14 mGy and 3-9 mSv in abdominopelvic CT.  Doses for organs at the boundaries of scan length were higher for 64-slice CT scanners using large beam widths and/or large pitch because of larger extent of overranging.  CTDIvol, DLP and the effective dose in 64-slice CT for the adult and paediatric phantoms were the same levels as those obtained in 4, 8 and 16-slice CT.  Conversion factors of DLP to the effective dose by ICRP Pub.103 were 0.024 and 0.019 mSv mGy-1 cm-1 for respectively adult chest and adult abdominopelvic CT scans.","subitem_description_type":"Abstract"}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://bjr.birjournals.org/cgi/reprint/82/984/1010"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://bjr.birjournals.org/cgi/reprint/82/984/1010","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0007-1285","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":"Fujii, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"454161","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aoyama, Takahiko"}],"nameIdentifiers":[{"nameIdentifier":"454162","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawaura, Chiyo"}],"nameIdentifiers":[{"nameIdentifier":"454163","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koyama, Shuji"}],"nameIdentifiers":[{"nameIdentifier":"454164","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamauchi, Masato"}],"nameIdentifiers":[{"nameIdentifier":"454165","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ko, Susumu"}],"nameIdentifiers":[{"nameIdentifier":"454166","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akahane, Keiichi"}],"nameIdentifiers":[{"nameIdentifier":"454167","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishizawa, Kanae"}],"nameIdentifiers":[{"nameIdentifier":"454168","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤井 啓輔","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"454169","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"赤羽 恵一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"454170","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西澤 かな枝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"454171","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":"Radiation dose evaluation in 64-slice CT examinations with adult and paediatric anthropomorphic phantoms","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radiation dose evaluation in 64-slice CT examinations with adult and paediatric anthropomorphic phantoms"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-24"},"publish_date":"2009-12-24","publish_status":"0","recid":"45698","relation_version_is_last":true,"title":["Radiation dose evaluation in 64-slice CT examinations with adult and paediatric anthropomorphic phantoms"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:00:42.650207+00:00"}
