We are developing a PET detector which consists of a scintillation crystal array and a silicon photomultiplier array. In addition, the capability of the depth-of-interaction (DOI) is required to high performance PET to reduce the parallax error degrading the uniformity of spatial resolution. We are studying the four-layer DOI PET detector wit a silicon photomultiplier array.\n The four-layer DOI detector consists of a 6x6x4 LYSO crystal array and the SPMArray (SPMsrray3035G16, SensL, Ireland) of the array of sixteen silicon photomultiplier detectors (each 3mm x 3mm). The size of each crystal element is 1.46 mm x 1.46 mm x 4.5 mm. The DOI encoding method was applied the previously presented methods which can identify crystals of four layers with only one photo detector and crystal array by the arrangement of the reflector inserted between crystals. We measured the performance of the four-layer DOI PET detector. Additionally, the related characteristics of SPMArray in the case of being used in the four-layer DOI PET detector were measured.\n As a result, the crystal identification was as similar as the detector which consisted of the same crystal array and the position sensitive photomultiplier tube we typically used. Sufficient energy resolution as a PET detector was obtained. We will present more detail results of the experiment.","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":"2008 Nuclear Science Symposium, 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":"682552","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"682553","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Kengo"}],"nameIdentifiers":[{"nameIdentifier":"682554","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"682555","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"682556","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Ichiro"}],"nameIdentifiers":[{"nameIdentifier":"682557","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Keishi"}],"nameIdentifiers":[{"nameIdentifier":"682558","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"682559","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682560","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682561","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"澁谷 憲悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682562","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682563","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682564","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 圭司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682565","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"682566","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":"Four-Layer DOI-PET Detector with a Silicon Photomultiplier Array","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Four-Layer DOI-PET Detector with a Silicon Photomultiplier Array"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-28"},"publish_date":"2008-10-28","publish_status":"0","recid":"69544","relation_version_is_last":true,"title":["Four-Layer DOI-PET Detector with a Silicon Photomultiplier Array"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:13:15.473344+00:00"}
