These characteristics were evaluated by measuring the characteristic curves, presampled modulation transfer function, Wiener spectrum, and energy dependence. In addition, the detective quantum efficiency (DQE), which was calculated based on the measurements of these characteristics, was evaluated. The indirect conversion FPD imaging system showed better sharpness and graininess characteristics compared with a computed radiography (CR) imaging system. The DQE of the indirect conversion FPD system was higher than that of the CR system at all frequencies. Indirect conversion FPD showed tube voltage characteristics with the best granularity for the FPD system at 80 kV (36.6 keV). Based on the evaluation of the basic imaging characteristics of the indirect conversion FPD system, it was concluded that the system has the potential to provide low exposure and high image quality.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"純真学園大学"}]},"item_10002_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"純真学園大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12581584","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2186-6481","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1710308327429":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"【資料】間接変換型Flat Panel Detector システムの画質特性の 観点からみた撮影条件の検討","subitem_title_language":"ja"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"村上, 誠一"},{"creatorName":"ムラカミ, セイイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"髙木, 剛司"},{"creatorName":"タカキ, タケシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大田, 哲"},{"creatorName":"オオタ, サトル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MURAKAMI, Seiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAKI, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OOTA, Satoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-04-08"}],"displaytype":"detail","filename":"純真学園大学雑誌-11号_p135-144.pdf","filesize":[{"value":"4.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"純真学園大学雑誌-11号_p135-144","url":"https://junshin.repo.nii.ac.jp/record/325/files/純真学園大学雑誌-11号_p135-144.pdf"},"version_id":"a0ae883b-466f-4187-bd1e-d70a0722332a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"間接変換型FPD","subitem_subject_scheme":"Other"},{"subitem_subject":"画質特性","subitem_subject_scheme":"Other"},{"subitem_subject":"管電圧依存性","subitem_subject_scheme":"Other"},{"subitem_subject":"デジタル画像","subitem_subject_scheme":"Other"},{"subitem_subject":"Computed Radiography（CR）","subitem_subject_scheme":"Other"},{"subitem_subject":"FPD （indirect conversion flat panel detector）","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image quality characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"energy dependence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"digital image","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Computed Radiography（ CR）","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"【資料】間接変換型Flat Panel Detector システムの画質特性の 観点からみた撮影条件の検討","item_type_id":"10002","owner":"12","path":["91"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-04-08"},"publish_date":"2021-04-08","publish_status":"0","recid":"325","relation_version_is_last":true,"title":["【資料】間接変換型Flat Panel Detector システムの画質特性の 観点からみた撮影条件の検討"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-04-26T06:36:08.898346+00:00"}
