To overcome the difficulty, we newly developed an X-ray CT system using multi-pixel photon counters (MPPCs), instead of photodiodes which have been used for conventional X-ray CT. We found that the MPPC CT system can drastically reduce the radiation dose by a factor of ~100 compared with the conventional X-ray CT, thereby indicating great potential for low-dose CT imaging. Furthermore, we demonstrated the multi-color X-ray CT imaging and successfully developed a multi-channel MPPC array system. These results show that we succeeded in establishment of the core technology for future low-dose and multi-color X-ray CT using MPPCs.","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:16H07266, 研究期間(年度):2016-08-26 - 2018-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「低被ばく多色X線CTシステムへ向けた基盤技術の確立」課題番号16H07266\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-16H07266/16H07266seika/)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":"金沢大学理工研究域数物科学系 / 早稲田大学","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00056625","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=40467014"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=40467014","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16H07266/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16H07266/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16H07266/16H07266seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-16H07266/16H07266seika/","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"有元, 誠"}],"nameIdentifiers":[{"nameIdentifier":"91121","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40467014","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40467014"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-27"}],"displaytype":"detail","filename":"SC-PR-ARIMOTO-M-kaken 2018-5p.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-ARIMOTO-M-kaken 2018-5p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/50316/files/SC-PR-ARIMOTO-M-kaken 2018-5p.pdf"},"version_id":"9f306da8-f052-46c4-a022-3d78b8bfd842"}]},"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":"低被ばく多色X線CTシステムへ向けた基盤技術の確立","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低被ばく多色X線CTシステムへ向けた基盤技術の確立"},{"subitem_title":"Establishment of core technology for low-dose and multi-color X-ray CT system","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2816"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-01-27"},"publish_date":"2020-01-27","publish_status":"0","recid":"50316","relation_version_is_last":true,"title":["低被ばく多色X線CTシステムへ向けた基盤技術の確立"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T05:32:34.643224+00:00"}
