Among these, development of the 2D detector is one of the main tasks because it should have as wide a dynamic range and as high a data acquisition speed (view rate) as present CT detectors.  We are now developing a 4D CT scanner together with the key components.  It will take one volume image in 0.5 sec with a 3D matrix of 512x512x512.  This paper describes the concepts and designs of the 4D CT system, as well as preliminary development of the 2D detector.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0288-2043","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":"Endo, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"440376","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsunoo, Takanori"}],"nameIdentifiers":[{"nameIdentifier":"440377","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kandatsu, Susumu"}],"nameIdentifiers":[{"nameIdentifier":"440378","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanada, Shuji"}],"nameIdentifiers":[{"nameIdentifier":"440379","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aradate, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"440380","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saito, Yasuo"}],"nameIdentifiers":[{"nameIdentifier":"440381","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"遠藤 真広","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440382","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"角尾 卓紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440383","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神立 進","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440384","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"棚田 修二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440385","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":"Four-dimensional computed tomography (4D CT) - Concepts and preliminary development","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Four-dimensional computed tomography (4D CT) - Concepts and preliminary development"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-23"},"publish_date":"2006-06-23","publish_status":"0","recid":"44333","relation_version_is_last":true,"title":["Four-dimensional computed tomography (4D CT) - Concepts and preliminary development"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:16:41.702741+00:00"}
