The patient dose depends on the X-ray quality that is derived from the target/filter combination, and a calibration of the dosimeter that is used in the measurement that corresponds to the specific target/filter combination is necessary. However, dosimeters in mammography are generally calibrated with reference to the X-ray quality of Mo/Mo or W/Al combinations, and it is unclear whether or not the X-ray quality that is derived from other target/filter combinations will affect the calibration coefficients. In this paper, the calibration coefficients of different dosimeters were evaluated for target/filter combinations. For an ionization chamber-type dosimeter, good energy dependence was found and the effect of the target/filter combination was small. However, for a semiconductor dosimeter, a large energy dependence was found, and different calibration coefficients that depended on the target/filter combination used were required.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Association of Physicists in Medicine"}]},"item_5_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"26699570","subitem_relation_type_select":"PMID"}}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1526-9914","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12034060","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sekimoto, Michiharu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Katoh, Yoh"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Katoh, Tsuguhisa"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-03"}],"displaytype":"detail","filename":"JACMP_12-6.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"JACMP_12-6","url":"https://tsukuba.repo.nii.ac.jp/record/37292/files/JACMP_12-6.pdf"},"version_id":"62710db0-2989-4351-9e17-bc47258429db"}]},"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":"Calibration coefficients of dosimeters used in mammography for various target/filter combinations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Calibration coefficients of dosimeters used in mammography for various target/filter combinations"}]},"item_type_id":"5","owner":"1","path":["4964","4942"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-03"},"publish_date":"2016-03-03","publish_status":"0","recid":"37292","relation_version_is_last":true,"title":["Calibration coefficients of dosimeters used in mammography for various target/filter combinations"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:06:49.223649+00:00"}
