For example, magnetic resonance imaging and computed tomography, etc., are those already established imaging techniques. Accordingly many related image processing techniques have been developed and reported in medical imaging fields. In the field of X-ray CT images, to segment of liver region several approaches are reported in the past. Many of them are needs knowledge-based schemes based on fuzzy logic or 3-D structural such as a blood vessel. It is therefore, for numerical representation automatic extraction of the liver region and classification of shadow candidate is required. In this paper, we propose a technique for automatic extraction of liver areas and its classification of shadow by computer employing a set of abdominal CT images. In the first stage, we extract a region of liver area from the given 2-D CT images. In the next stage, abnormal area is extracted employing subtraction technique. The technique was applied to three abdominal CT image sets and satisfactory results were obtained.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"バイオメディカル・ファジィ・システム学会","subitem_publisher_language":"ja"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.24466/jbfsa.6.1_42","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","attribute_value_mlt":[{"subitem_rights":"バイオメディカル・ファジィ・システム学会. 本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA1145146X","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2424-2578","subitem_source_identifier_type":"EISSN"},{"subitem_source_identifier":"1345-1537","subitem_source_identifier_type":"PISSN"}]},"item_21_text_64":{"attribute_name":"業績ID","attribute_value_mlt":[{"subitem_text_value":"ECB49D2212470F244925756700091944"}]},"item_21_version_type_58":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAlternatives":[{"creatorAlternative":"Kamiya, Tohru","creatorAlternativeLang":"en"},{"creatorAlternative":"神谷, 亨","creatorAlternativeLang":"ja"},{"creatorAlternative":"カミヤ, トオル","creatorAlternativeLang":"ja-Kana"}],"creatorNames":[{"creatorName":"Kim, Hyungseop","creatorNameLang":"en"},{"creatorName":"金, 亨燮","creatorNameLang":"ja"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"萩原, 圭太","creatorNameLang":"ja"},{"creatorName":"Hagiwara, Keita","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"Ishikawa, Seiji","creatorNameLang":"en"},{"creatorName":"石川, 聖二","creatorNameLang":"ja"},{"creatorName":"イシカワ, セイジ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"四宮, 孝史","creatorNameLang":"ja"},{"creatorName":"Shinomiya, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佃, 正明","creatorNameLang":"ja"},{"creatorName":"Tsukuda, Masaaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2009-02-24"}],"displaytype":"detail","filename":"kim_03.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kim_03.pdf","url":"https://kyutech.repo.nii.ac.jp/record/1128/files/kim_03.pdf"},"version_id":"0c0235d8-0ceb-400d-a65c-0a39d98428bf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CT画像","subitem_subject_scheme":"Other"},{"subitem_subject":"肝臓領域","subitem_subject_scheme":"Other"},{"subitem_subject":"CT image","subitem_subject_scheme":"Other"},{"subitem_subject":"CAD","subitem_subject_scheme":"Other"},{"subitem_subject":"liver Area","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":"腹部CT像からの肝臓領域と異常陰影候補領域の抽出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"腹部CT像からの肝臓領域と異常陰影候補領域の抽出","subitem_title_language":"ja"},{"subitem_title":"Automatic extraction of liver regions and classification of shadow candidate from abdominal CT images","subitem_title_language":"en"}]},"item_type_id":"21","owner":"14","path":["24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-02-24"},"publish_date":"2009-02-24","publish_status":"0","recid":"1128","relation_version_is_last":true,"title":["腹部CT像からの肝臓領域と異常陰影候補領域の抽出"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-10-26T05:05:18.412289+00:00"}
