However, an EP Navigator allows seamless integration of 3D anatomy obtained through 3D rotational angiography (3D-ATG) into an electroanatomical mapping system. We hypothesized that 3D-ATG can be used during AF ablation while significantly reducing the effective dose (ED) and without compromising image morphology compared to a 3D-CT image. Organ dose was measured at 37 points with a radiophotoluminescence glass dosimeter inserted in an anthropomorphic Rando Phantom. The ED was calculated by multiplying the organ dose by the tissue weighting factor. The dose-area product (DAP)-to-ED conversion factor was calculated by measuring the DAP during radiation exposure. The ED for the CT examination was estimated from the dose-length product with a conversion factor of 0.014. ED was calculated from DAP measurements in 114 patients undergoing AF ablation using 3D-ATG. The DAP-to-ED conversion factor for 3D-ATG was 2.4 × 10-4 mSv/mGy cm2 in our hospital. The mean DAP for all patients was 7777 ± 1488 mGy cm2 for the 3D-ATG of the left atrium. The corresponding ED for 3D-ATG was 1.9 ± 0.4 mSv. The ED for CT examinations was 13.6 ± 4.2 mSv (P < 0.001). 3D-ATG can be used during AF ablation while significantly reducing the ED and without compromising image morphology.","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文 /  Department of Cardiology and Nephrology, Mie University Graduate School of Medicine, 2-174 Edobashi, Tsu, Mie, 514-8507, Japan","subitem_description_type":"Other"},{"subitem_description":"8p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙医学第1022号"}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00380-018-1180-y","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Heart Vessels November 2018,Volume 33,Issue 11,1373–1380 に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"item_7_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fujita, Satoshi","creatorNameLang":"en"},{"creatorName":"フジタ, サトシ","creatorNameLang":"ja-Kana"},{"creatorName":"藤田, 聡","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-19"}],"displaytype":"detail","filename":"2018DM0912.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2018DM0912.pdf","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/12300/files/2018DM0912.pdf"},"version_id":"4d00aaab-1fff-4d97-8312-7f90c283f095"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Atrial fibrillation","subitem_subject_scheme":"Other"},{"subitem_subject":"Catheter ablation","subitem_subject_scheme":"Other"},{"subitem_subject":"Rotational angiography","subitem_subject_scheme":"Other"},{"subitem_subject":"Seamless integration of 3D anatomy","subitem_subject_scheme":"Other"},{"subitem_subject":"Effective dose","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"The seamless integration of three-dimensional angiography images into electroanatomical mapping systems to guide catheter ablation of atrial fibrillation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The seamless integration of three-dimensional angiography images into electroanatomical mapping systems to guide catheter ablation of atrial fibrillation","subitem_title_language":"en"}]},"item_type_id":"7","owner":"16","path":["915"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-02-19"},"publish_date":"2019-02-19","publish_status":"0","recid":"12300","relation_version_is_last":true,"title":["The seamless integration of three-dimensional angiography images into electroanatomical mapping systems to guide catheter ablation of atrial fibrillation"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-10-31T06:01:42.892822+00:00"}
