In recent years, Iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) using 3-points Dixon technique become used as the useful method for uniform fat suppression at the magnetic field inhomogeneity. However, misregistration artifact appeared under some conditions. Purpose of this study is searching for conditions of misregistration artifact on IDEAL method.\n We have created the phantom which had contained oil, water and the titanium. The relation of misregistration artifact and seed-point of region growing technique was analyzed by shifting the position of metal, changing the position of FOV. Misregistration artifact on IDEAL method was sometimes occurred to existence the metal at center of phantom under the  each conditions.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_15_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"熊本大学","subitem_publisher_language":"ja"}]},"item_15_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-7151","subitem_source_identifier_type":"PISSN"}]},"item_15_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12010572","subitem_source_identifier_type":"NCID"}]},"item_15_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"492.1","subitem_subject_scheme":"NDC"}]},"item_15_version_type_19":{"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":"坂本, 崇","creatorNameLang":"ja"},{"creatorName":"サカモト, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"Sakamoto, Takashi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"栗栖, 健郎","creatorNameLang":"ja"},{"creatorName":"クリス, ケンロウ","creatorNameLang":"ja-Kana"},{"creatorName":"Kurisu, Kenro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"上田, 新也","creatorNameLang":"ja"},{"creatorName":"ウエダ, シンヤ","creatorNameLang":"ja-Kana"},{"creatorName":"Ueda, Shinya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"竹村, 信房","creatorNameLang":"ja"},{"creatorName":"タケムラ, ノブフサ","creatorNameLang":"ja-Kana"},{"creatorName":"Takemura, Nobufusa","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"肥合, 康弘","creatorNameLang":"ja"},{"creatorName":"ヒアイ, ヤスヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"Hiai, Yasuhiro","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-03-02"}],"displaytype":"detail","filename":"MH0008_023-030.pdf","filesize":[{"value":"793.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"MH0008_023-030.pdf","url":"https://kumadai.repo.nii.ac.jp/record/26285/files/MH0008_023-030.pdf"},"version_id":"9d4be30c-966b-48ac-857a-9db319a4b436"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"MRI","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"artifact","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fat suppression","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dixon","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"IDEAL","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":"IDEAL法における計算不良アーチファクトについての検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"IDEAL法における計算不良アーチファクトについての検討","subitem_title_language":"ja"},{"subitem_title":"IDEALホウ ニ オケル ケイサン フリョウ アーチファク ト ニ ツイテ ノ ケントウ","subitem_title_language":"ja-Kana"},{"subitem_title":"Examination of Misregistration Artifact on Iterative Decomposition of Water and Fat with Echo Asymmetry and Least-Squares Estimation (IDEAL) Method","subitem_title_language":"en"}]},"item_type_id":"15","owner":"128","path":["414","1261"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-05-16"},"publish_date":"2012-05-16","publish_status":"0","recid":"26285","relation_version_is_last":true,"title":["IDEAL法における計算不良アーチファクトについての検討"],"weko_creator_id":"128","weko_shared_id":-1},"updated":"2025-12-11T06:16:10.787227+00:00"}
