To measure CNR, we filled 0.125–1.0-inch cavities in an American Association of Physicists in Medicine (AAPM) CT performance phantom with a sodium chloride solution. Five radiological technologists visually evaluated the noise, signal conspicuity at low-and high-signal density, and the overall image quality using paired comparisons based on Thurstone’s law. In a given acquisition matrix, the total view number had the greatest effect on the image noise, artifacts, and signal detectability on C-arm CT images. For a given incident dose per view on the flat-panel detector (FPD), fewer images with noise and streak artifacts resulted when a larger view number was selected.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"http://www.jstage.jst.go.jp/article/jjrt/65/6/65_765/_article/-char/ja/","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人　日本放射線技術学会"}]},"item_16_relation_16":{"attribute_name":"情報源(ISSN)","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"03694305"}]}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2009 Japanese Society of Radiological Technology"}]},"item_16_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00197784","subitem_source_identifier_type":"NCID"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"492.4","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"1898899 bytes"}]},"item_16_text_38":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_text_value":"Japanese Society of Radiological Technology"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"永末, 望"}],"nameIdentifiers":[{"nameIdentifier":"111311","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"船間, 芳憲"},{"creatorName":"フナマ, ヨシノリ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"146914","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鬼木, 里佳"}],"nameIdentifiers":[{"nameIdentifier":"111313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"瀬川, 敦史"}],"nameIdentifiers":[{"nameIdentifier":"111314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩竹, 聡"}],"nameIdentifiers":[{"nameIdentifier":"111315","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川内野, 友彦"}],"nameIdentifiers":[{"nameIdentifier":"111316","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"上谷, 雅孝"}],"nameIdentifiers":[{"nameIdentifier":"111317","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-03-02"}],"displaytype":"detail","filename":"65_765.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"65_765.pdf","url":"https://kumadai.repo.nii.ac.jp/record/24762/files/65_765.pdf"},"version_id":"d6e664ca-1ad3-42f0-b2ad-084191e09a83"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"C-arm CT","subitem_subject_scheme":"Other"},{"subitem_subject":"scan protocol","subitem_subject_scheme":"Other"},{"subitem_subject":"image quality","subitem_subject_scheme":"Other"},{"subitem_subject":"radiation dose","subitem_subject_scheme":"Other"},{"subitem_subject":"abdominal imaging","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"腹部領域のC-arm CTにおけるスキャンパラメータと画質","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"腹部領域のC-arm CTにおけるスキャンパラメータと画質"}]},"item_type_id":"16","owner":"1","path":["443"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-06-07"},"publish_date":"2011-06-07","publish_status":"0","recid":"24762","relation_version_is_last":true,"title":["腹部領域のC-arm CTにおけるスキャンパラメータと画質"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-19T16:42:57.189850+00:00"}
