This 3D computed tomography (CT) system is based on a cone beam and video-fluoroscopic system and yields data that is amenable to 3D image processing. An X-ray tube and a large area two-dimensional detector were mounted on a single frame and rotated around objects in 12 seconds. The large area detector consisted of a fluorescent plate and a charge coupled device (CCD) video camera. While tha X-ray tube was rotated around the object, a pulsed X-ray was generated (30 pulses per second) and 360 projected images were collected in a 12-second scan. A 256x256x256 matrix image was reconstructed using a high-speed parallel processor. Reconstruction required approximately 6 minutes. Two volunteers under-went scans of the head or chest. High-contrast objects such as bronchial, vascular, and mediastinal structures in the thorax, or bones ans air cavities in the head were delineated in a \"real\" 3D format. Our 3D CT-scanner appears to produce data useful for clinical imaging and 3D image processing.","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":"遠藤, 真広"}],"nameIdentifiers":[{"nameIdentifier":"440922","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田, 勝哉"}],"nameIdentifiers":[{"nameIdentifier":"440923","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"日下部, 正宏"}],"nameIdentifiers":[{"nameIdentifier":"440924","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"舘野, 之男"}],"nameIdentifiers":[{"nameIdentifier":"440925","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"その他"}],"nameIdentifiers":[{"nameIdentifier":"440926","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"遠藤 真広","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440927","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 勝哉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"日下部 正宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"舘野 之男","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440930","nameIdentifierScheme":"WEKO"}]}]},"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":"Development of a 3D CT-Scanner Using a Cone Beam and Video-Fluoroscopic System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a 3D CT-Scanner Using a Cone Beam and Video-Fluoroscopic System"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-29"},"publish_date":"2006-06-29","publish_status":"0","recid":"44373","relation_version_is_last":true,"title":["Development of a 3D CT-Scanner Using a Cone Beam and Video-Fluoroscopic System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:16:12.870686+00:00"}
