However, the presence of a metal prosthesis, such as dental fillings, leads to metal artifacts in the CT images that degrade the segmentation accuracy. In our previous study, we developed a musculoskeletal segmentation method applied to metal artifact-reduced CT images and evaluated it based on the manual trace produced from metal artifact-reduced CT images. In this research, instead, we simulated metal artifacts in the CT images and evaluated the segmentation accuracy using labels produced from CT images without metal artifact. In addition, we proposed an improvement of the conventional Normalized Metal Artifact Reduction (NMAR) method, and compared the impact of three metal artifact reduction methods on the segmentation accuracy.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10007_description_14":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"・2018(平成30)年度 科学研究費補助金 基盤研究(C) 研究成果報告書","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究期間 (年度)：2016-04-01 – 2019-03-31","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究分野：補綴学","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究成果の学術的意義や社会的意義 : 歯科補綴は，補綴装置により欠損した顔面形態，顎骨や歯を補い機能を回復することにあるが，その環境は様々であり，固有の形態に合致し，良好な機能を回復することは難しい．本研究では，顎顔面頭蓋や歯列，歯の形態の様々なデジタル情報を用いて統計解析（計算解剖学的手法）を行うことにより患者個別に最適な解剖学的形態を算出，CAD/CAM技術に応用し，機能に即した顎顔面補綴装置や口腔内の修復装置を設計・製作することが目的である．これは個々に存在している多種多様な情報を効果的（有機的）に統合する手法であり，様々な研究へ展開可能である．","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10007_description_9":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号 : 16K11615","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10007_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-16K11615/","subitem_relation_type_select":"URI"}}]},"item_10007_version_type_20":{"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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-03-16"}],"displaytype":"detail","filename":"16K11615.pdf","filesize":[{"value":"657.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"16K11615","url":"https://tsurumi-u.repo.nii.ac.jp/record/1045/files/16K11615.pdf"},"version_id":"1d46faac-8a36-4413-a2db-ff90706181fa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"計算解剖学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"CADCAMシステム","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"デジタルデンティストリー","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"セグメンテーション","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_researcher":{"attribute_name":"研究代表者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"IKAWA, Tomoko","creatorNameLang":"en"},{"creatorName":"井川, 知子","creatorNameLang":"ja"},{"creatorName":"イカワ, トモコ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"IKAWA","familyNameLang":"en"},{"familyName":"井川","familyNameLang":"ja"},{"familyName":"イカワ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tomoko","givenNameLang":"en"},{"givenName":"知子","givenNameLang":"ja"},{"givenName":"トモコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"791","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70552389","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70552389"},{"nameIdentifier":"791","nameIdentifierScheme":"WEKO著者ID"}]}]},"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":"補綴治療に応用できる計算解剖学的手法に基づいた顎顔面統計アトラスの構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"補綴治療に応用できる計算解剖学的手法に基づいた顎顔面統計アトラスの構築","subitem_title_language":"ja"},{"subitem_title":"Construction of the maxillofacial statistics atlas based on Computational anatomy technique to apply to prosthodontic treatment","subitem_title_language":"en"}]},"item_type_id":"10007","owner":"10","path":["160"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-03-16"},"publish_date":"2022-03-16","publish_status":"0","recid":"1045","relation_version_is_last":true,"title":["補綴治療に応用できる計算解剖学的手法に基づいた顎顔面統計アトラスの構築"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-08-01T23:06:50.434843+00:00"}
