Although physical methods are generally well established, psychological methods （in which the influence of the visual characteristics of diagnostic images is also taken into consideration） often suffer from difficulties in quantification.\nOne psychological evaluation method involves the use of a C-D diagram with a Burger phantom. However, this method is not applicable to modalities other than X-ray systems and parameter setting is difficult.\nIn the present study, a virtual Burger phantom was constructed on a PC based on the MTF and Wiener spectrum data of the imaging system which is the physical characteristic of image evaluation.\nThe validity of this method was confirmed by comparing phantom image data against actually acquired image data using X-ray systems.\nFurther research will be needed to confirm that this virtual Burger phantom should be applicable to other modalities than X-ray system.","subitem_description_type":"Other"}]},"item_10002_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"SUGIYAMA, Naoki"}]},{"nameIdentifiers":[{}],"names":[{"name":"IINUMA, Kazuhiro"}]}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国際医療福祉大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1059280X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13424661","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-21"}],"displaytype":"simple","filename":"10(7-18p).pdf","filesize":[{"value":"813.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文(PDF)","url":"https://iuhw.repo.nii.ac.jp/record/124/files/10(7-18p).pdf"},"version_id":"1fdf1e35-551d-408b-91bc-4c7d561e6b24"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"医用画像","subitem_subject_scheme":"Other"},{"subitem_subject":"画質評価","subitem_subject_scheme":"Other"},{"subitem_subject":"ファントム","subitem_subject_scheme":"Other"},{"subitem_subject":"medical image","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image quality evaluation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phantom","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":"仮想Burgerファントムの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"仮想Burgerファントムの開発"},{"subitem_title":"Development of virtual burger phantom","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"15","path":["18"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-06-07"},"publish_date":"2012-06-07","publish_status":"0","recid":"124","relation_version_is_last":true,"title":["仮想Burgerファントムの開発"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-05-15T09:27:43.258327+00:00"}
