In addition, we have proposed real-time imaging system for the OpenPET which is expected to be used in PET-guided tumor tracking radiation therapy. The tracking ability of the system has been demonstrated using a point source and a small OpenPET prototype. However, tumor tracking in human body still remains as a challenging task when we use PET tracer for tumors because the number of counts in short time frame is small and noises from background activity, scatter and attenuation are unavoidable. In this study, we assess conditions under which tumor tracking is feasible in the human body by using the 4D XCAT phantom which is a realistic 4D human whole body phantom. We conducted Monte Carlo simulation of a human-sized OpenPET geometry by using GATE toolkit assigning typical SUVs in 18F-FDG study to normal organs based on the literature. As a result, we showed that tumor tracking by the OpenPET is feasible even in the human body scale and for realistic conditions when the tumor contains enough radioactivity.","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":"2nd SNU-NIRS workshop on nuclear medicine imaging science and technology","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":"640348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"640349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinaji, Tetsuya"}],"nameIdentifiers":[{"nameIdentifier":"640350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirano, Yoshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"640351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"640352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Haneishi, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"640353","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"640354","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"640355","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島 英朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640356","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640357","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"品地 哲弥","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640358","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平野 祥之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640359","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640360","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽石 秀昭","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640361","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤 浩","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640362","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"640363","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":"Monte Carlo simulation of real-time tumor tracking by the OpenPET using the 4D XCAT phantom with a realistic 18F-FDG distribution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Monte Carlo simulation of real-time tumor tracking by the OpenPET using the 4D XCAT phantom with a realistic 18F-FDG distribution"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-02"},"publish_date":"2013-05-02","publish_status":"0","recid":"64986","relation_version_is_last":true,"title":["Monte Carlo simulation of real-time tumor tracking by the OpenPET using the 4D XCAT phantom with a realistic 18F-FDG distribution"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:05:20.804974+00:00"}
