Our detection method is based on the definition of lacunar infarcts. After inputted images were binarized, we used feature values such as area, circularities and the center of gravity of candidate regions to extract isolated lacunar infarct regions. We also developed and used a new filter to enhance the signals of lacunar infarcts adjacent to some high intensity regions. 10 cases involving 81 sectional images were applied to our experiment. As a result, the sensitivity was 100％ with approximately 1.77 false-positives per image. Our results are promising on the first stage, although it remains to improve on problems that to eliminate false-positives and automatically establish threshold value.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"47604","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yokoyama, Ryujiro"}]},{"nameIdentifiers":[{"nameIdentifier":"9","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Lee, Yongbum"}]},{"nameIdentifiers":[{"nameIdentifier":"47606","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hara, Takeshi"}]},{"nameIdentifiers":[{"nameIdentifier":"47607","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fujita, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"47608","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Asano, Takahiko"}]},{"nameIdentifiers":[{"nameIdentifier":"47609","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hoshi, Hiroaki"}]},{"nameIdentifiers":[{"nameIdentifier":"47610","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Iwama, Toru"}]},{"nameIdentifiers":[{"nameIdentifier":"47611","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakai, Noboru"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本放射線技術学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00197773","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03694305","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"横山, 龍二郎"}],"nameIdentifiers":[{"nameIdentifier":"47596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"李, 鎔範"}],"nameIdentifiers":[{"nameIdentifier":"9","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"原, 武史"}],"nameIdentifiers":[{"nameIdentifier":"47598","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤田, 広志"}],"nameIdentifiers":[{"nameIdentifier":"47599","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅野, 隆彦"}],"nameIdentifiers":[{"nameIdentifier":"47600","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"星, 博昭"}],"nameIdentifiers":[{"nameIdentifier":"47601","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩間, 亨"}],"nameIdentifiers":[{"nameIdentifier":"47602","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂井, 昇"}],"nameIdentifiers":[{"nameIdentifier":"47603","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-30"}],"displaytype":"detail","filename":"jrst_58_3_399_405_2002.pdf","filesize":[{"value":"124.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jrst_58_3_399_405_2002.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/4127/files/jrst_58_3_399_405_2002.pdf"},"version_id":"8fef3e76-91ff-440c-89c8-fe2ab0c8b3f4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Brain MR image","subitem_subject_scheme":"Other"},{"subitem_subject":"Lacunar infarct","subitem_subject_scheme":"Other"},{"subitem_subject":"Automated detection","subitem_subject_scheme":"Other"},{"subitem_subject":"Laplacian filter","subitem_subject_scheme":"Other"},{"subitem_subject":"Computer-aided diagnosis(CAD)","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"脳MR画像におけるラクナ梗塞領域の自動検出の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"脳MR画像におけるラクナ梗塞領域の自動検出の試み"},{"subitem_title":"脳MR画像におけるラクナ梗塞領域の自動検出の試み","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","508"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-05-29"},"publish_date":"2007-05-29","publish_status":"0","recid":"4127","relation_version_is_last":true,"title":["脳MR画像におけるラクナ梗塞領域の自動検出の試み"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:37:08.780856+00:00"}
