Each detector module consists of a 32 X 32 X 4 LYSO (Lu: 98%, Y: 2%) crystal array and a 256-channel flat panel position sensitive photomultiplier tube. The size of each crystal element is 1.46 mm X 1.46 mm X 4.5 mm. The crystal block (46.5 mm X 11.6 mm X 18.0 mm) is placed on the central area of a 256ch FP-PMT (49 mm X 49 mm useful area) and coupled with silicone rubber. \nIn the previous study, we succeeded at crystal identification for the detector module composed of the four layer crystal array and achieved the good performance as a detector for a small animal PET with a 32 X 8 X 4 LYSO array corresponding with a quarter of the full size crystal array. We evaluated the spatial resolution of reconstructed images with the one pair system of the two 4-Layer DOI detectors for jPET-RD.  The spatial resolutions of smaller than 2 mm in whole field of view by FBP algorithm were achieved. In addition, the spatial resolution of 1.5mm at the center of FOV was achieved.","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":"IEEE 2006 Nuclear Science Symposium and Medical Imaging Conference","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":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"674712","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuda, Tomoaki"}],"nameIdentifiers":[{"nameIdentifier":"674713","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"674714","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"674715","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Kei"}],"nameIdentifiers":[{"nameIdentifier":"674716","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Kengo"}],"nameIdentifiers":[{"nameIdentifier":"674717","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"674718","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Keishi"}],"nameIdentifiers":[{"nameIdentifier":"674719","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"674720","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674721","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"津田 倫明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674722","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674723","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674724","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 慧","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674725","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"澁谷 憲悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674726","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674727","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 圭司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674728","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"674729","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":"Spatial Resolution Measured by a Prototype System of Two 4-Layer DOI Detectors for jPET-RD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spatial Resolution Measured by a Prototype System of Two 4-Layer DOI Detectors for jPET-RD"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-11-07"},"publish_date":"2006-11-07","publish_status":"0","recid":"68753","relation_version_is_last":true,"title":["Spatial Resolution Measured by a Prototype System of Two 4-Layer DOI Detectors for jPET-RD"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:22:31.480509+00:00"}
