Therefore, a conventional CT, which is now clinically available, has a limited resolution. On the other hand, although a micro CT significantly improved the resolution, extension of the scanning time and in-accurate CT number were concerns. In order to improve the spatial resolution and overcome these shortcomings, we developed an ultrahigh-resolution (UHR) CT system constructed by adding a high-resolution CMOS detector with a 0.1-mm pixel pitch to a 16-row multislice CT scanner. This UHR-CT with contact geometry showed superior performance than conventional CT. It is expected that fine anatomical structures of bones and inner ear, which have not been sufficiently visualized by conventional CT scanners, can be clearly visualized by this system.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:17K16431, 研究期間(年度):2017-04-01 - 2020-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「近接ジオメトリ型超高解像度CTの開発」研究成果報告書　課題番号17K16431\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所））\n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-17K16431/17K16431seika/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域保健学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00057548","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=70775577"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=70775577","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17K16431/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17K16431/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-17K16431/17K16431seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-17K16431/17K16431seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-04-19"}],"displaytype":"detail","filename":"ME-PR-KAWASHIMA-H-kaken 2020-7p(2).pdf","filesize":[{"value":"260.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-KAWASHIMA-H-kaken 2020-7p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/51245/files/ME-PR-KAWASHIMA-H-kaken 2020-7p(2).pdf"},"version_id":"97696592-208d-4f33-8301-6e7e004f951e"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"近接ジオメトリ型超高解像度CTの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"近接ジオメトリ型超高解像度CTの開発"},{"subitem_title":"Development of ultra-high-resolution CT with contact geometry","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["3929"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-19"},"publish_date":"2021-04-19","publish_status":"0","recid":"51245","relation_version_is_last":true,"title":["近接ジオメトリ型超高解像度CTの開発"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:01:45.863793+00:00"}
