The jPET-RD is designed with two detector rings. Each detector ring is composed of six DOI detectors arranged hexagonally. The diameter of the field-of-view (FOV) is 8.8 cm, which is smaller than typical small animal PET scanners on the market now. Each detector module consists of a crystal block and a 256-channel flat panel position-sensitive photomultiplier tube. The crystal block, consisting of 32 x 32 x 4 crystal (4096 crystals, each 1.46 mm x 1.46 mm x 4.5 mm) and a reflector, is mounted on the 256ch FP-PMT.\n\\nIn this study, we evaluated the spatial resolution of reconstructed images with the evaluation system of two four-layer DOI detectors which consist of 32 x 32 x 4 LYSO (Lu: 98%, Y: 2%) crystals coupled on the 256ch FP-PMT by using RTV rubber. The spatial resolution of 1.5 mm was obtained at the center of the FOV by the filtered back projection. The spatial resolution, better than 2 mm in the whole FOV, was also achieved with DOI while the spatial resolution without DOI was degraded to 3.3 mm.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.nima.2007.10.001","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-9002","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":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"448544","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuda, Tomoaki"}],"nameIdentifiers":[{"nameIdentifier":"448545","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"448546","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"448547","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Kengo"}],"nameIdentifiers":[{"nameIdentifier":"448548","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"448549","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Keishi"}],"nameIdentifiers":[{"nameIdentifier":"448550","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Kei"}],"nameIdentifiers":[{"nameIdentifier":"448551","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohmura, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"448552","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"448553","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448554","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"津田 倫明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448555","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448556","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448557","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"澁谷 憲悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448558","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448559","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 圭司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448560","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 慧","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448561","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大村 篤史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448562","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"448563","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":"Spatial resolution evaluation with a pair of two four-layer DOI detectors for small animal PET scanner: jPET-RD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spatial resolution evaluation with a pair of two four-layer DOI detectors for small animal PET scanner: jPET-RD"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-24"},"publish_date":"2008-05-24","publish_status":"0","recid":"45165","relation_version_is_last":true,"title":["Spatial resolution evaluation with a pair of two four-layer DOI detectors for small animal PET scanner: jPET-RD"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:06:54.180675+00:00"}
