We experimentally obtained a three-dimensional (3D) isotope-selective CT image based on a NRF transmission method (3D NRF-CT) for the enriched lead isotope distribution of 208Pb in a previous study. Since the NRF-CT imaging technique requires a considerable data accumulation time, it took 48 h to obtain an image with a resolution of 4 mm/pixel in the horizontal plane and 8 mm/pixel in the vertical plane for a cylindrical sample with a diameter of 25 mm and a height of 20 mm using a laser Compton scattering (LCS) gamma-ray beam with a beam size of 2 mm and a flux density of 10 photons/s/eV. Improving the NRF-CT image resolution with the existing hardware is challenging. Therefore, we proposed an alternative method to improve the NRF-CT image quality using the fusion visualization (FV) technique by combining the NRF-CT image including isotopic information with a gamma-CT image, which provides better pixel resolution. The 3D gamma-CT image for the same sample was measured at the same beamline BL1U in the UVSOR-III synchrotron radiation facility under similar experimental conditions except for the LCS gamma-ray beam flux and beam size. Obtaining a 3D gamma-CT image with a resolution of 1 mm/pixel took 5 h using an LCS gamma-ray beam with a beam size of 1 mm and a flux density of 0.7 photons/s/eV. The data processing of the FV technique has been developed, and the 3D NRF-CT image quality was im-proved.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/app112411866","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.mdpi.com/2076-3417/11/24/11866","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2076-3417","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ali, Khaled"}],"nameIdentifiers":[{"nameIdentifier":"1040922","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zen, Heishun"}],"nameIdentifiers":[{"nameIdentifier":"1040923","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohgaki , Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"1040924","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kii, Toshiteru"}],"nameIdentifiers":[{"nameIdentifier":"1040925","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayakawa, Takehito"}],"nameIdentifiers":[{"nameIdentifier":"1040926","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shizuma, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"1040927","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katoh, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"1040928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taira, Yoshitaka"}],"nameIdentifiers":[{"nameIdentifier":"1040929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujimoto, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"1040930","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toyokawa, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"1040931","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takehito, Hayakawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1040932","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toshiyuki, Shizuma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1040933","nameIdentifierScheme":"WEKO"}]}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Fusion Visualization Technique to Improve a Three-Dimensional Isotope-Selective CT Image Based on Nuclear Resonance Fluo-rescence with a Gamma-CT Image","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fusion Visualization Technique to Improve a Three-Dimensional Isotope-Selective CT Image Based on Nuclear Resonance Fluo-rescence with a Gamma-CT Image"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-25"},"publish_date":"2021-11-25","publish_status":"0","recid":"84906","relation_version_is_last":true,"title":["Fusion Visualization Technique to Improve a Three-Dimensional Isotope-Selective CT Image Based on Nuclear Resonance Fluo-rescence with a Gamma-CT Image"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:24:18.033633+00:00"}
