For the real-time imaging system, we are intending to use one-pass list-mode dynamic row-action\nmaximum likelihood algorithm (DRAMA) and implement it using general-purpose computation on graphics processing\nunit techniques. However, it is difficult to consistently reconstruct in real-time because the amount of data acquired in PET\nscan can be large depending on the activity. In this study, we developed a system to control the data used in the\nreconstruction step keeping quantitative performance. In the proposed system, data transfer control system limits the event\ncount to be used in the reconstruction step according to the reconstruction speed, and the reconstructed images are properly\nintensified by using ratio of the used count to the total count. We implemented the system on a small OpenPET prototype\nsystem and evaluated the performance in terms of the real-time tracking ability by displaying projection images in which the\nintensity was compensated. The intensity of the displayed image was properly correlated with the original event number\nwithout delay. By the conference, we will incorporate real-time reconstruction system using one-pass list-mode DRAMA to\ndisplay 3D images in real-time.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"2010IEEE NSS&MIC","subitem_description_type":"Other"}]},"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":"Tashima, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"690579","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"690580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kinouchi, Shoko"}],"nameIdentifiers":[{"nameIdentifier":"690581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suga, Mikio"}],"nameIdentifiers":[{"nameIdentifier":"690582","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"690583","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"690584","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"690585","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"690586","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島 英朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690587","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690588","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木内 尚子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690589","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅 幹生","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690590","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690591","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690592","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690593","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"690594","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Real-Time Imaging System for a Small OpenPET Prototype","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Real-Time Imaging System for a Small OpenPET Prototype"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-15"},"publish_date":"2010-11-15","publish_status":"0","recid":"70325","relation_version_is_last":true,"title":["Real-Time Imaging System for a Small OpenPET Prototype"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:04:14.399669+00:00"}
