In this study, an ultra-sensitive SQUID magnetic sensor, which has extremely high sensitivity in low frequency range, which correspond to Larmor frequency in ULF, was used in the ULF NMR/MRI system. Using the system, we showed that the signal amplitude and line width of NMR signal in ULF increased and decreased with the static field intensity, respectively. Achievement of MRI in ULF was also demonstrated. We also studied possibility of realization of ULF NMR/MRI in normal environment, by combining robust SQUID and noise cancelling techniques.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2013～2015;   課題番号：25420406;   研究分野：計測工学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25420406/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"連携研究者"},{"subitem_text_value":"連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"HATSUKADE, Yoshimi"},{"subitem_text_language":"en","subitem_text_value":"TANAKA, Saburo"},{"subitem_text_language":"en","subitem_text_value":"YOSHIDA, Sachiko"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学工学部; 准教授"},{"subitem_text_value":"豊橋技術科学大学工学（系）研究科（研究院）; 教授"},{"subitem_text_value":"豊橋技術科学大学工学（系）研究科（研究院）; 講師"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"廿日出, 好"},{"creatorName":"ハツカデ, ヨシミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"田中, 三郎"},{"creatorName":"タナカ, サブロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"吉田, 祥子"},{"creatorName":"ヨシダ, サチコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-15"}],"displaytype":"detail","filename":"25420406seika.pdf","filesize":[{"value":"363.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25420406seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18149/files/25420406seika.pdf"},"version_id":"86ac5e66-7b5e-4341-981e-03b762317355"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超低磁場","subitem_subject_scheme":"Other"},{"subitem_subject":"NMR","subitem_subject_scheme":"Other"},{"subitem_subject":"MRI","subitem_subject_scheme":"Other"},{"subitem_subject":"SQUID","subitem_subject_scheme":"Other"},{"subitem_subject":"磁場耐性","subitem_subject_scheme":"Other"},{"subitem_subject":"ノイズ除去","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"超低磁場を用いた機能的MRIマイクロスコピー","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超低磁場を用いた機能的MRIマイクロスコピー"},{"subitem_title":"Functional MRI microscopy in ultra-low field","subitem_title_language":"en"}]},"item_type_id":"8","owner":"29","path":["4296"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-15"},"publish_date":"2016-10-15","publish_status":"0","recid":"18149","relation_version_is_last":true,"title":["超低磁場を用いた機能的MRIマイクロスコピー"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2023-06-20T22:06:47.410129+00:00"}
