In this work, we developed the DOI-TOF detector based on our original singleended readout scheme with the continuous layered gadolinium fine aluminum garnet (GFAG) array. The size of each GFAG crystal is 1.45×1.45×20 mm3. The multi-pixel photon counter (MPPC) used as a photo-sensor has a surface area of 3.0×3.0 mm2. One pair of crystals coupled with a partial optical window is arranged across two MPPCs. Boundaries without the partial optical window are covered with optical reflectors. Each pair is coupled with paired MPPCs of different patterns. Crystal identification is obtained from paired MPPCs of different patterns and output rates. By limiting the spread of scintillation light, the proposed DOI detector based on the local centroid calculation was expected to improve crystal response including the edge. For performance comparison, we prepared three discrete layers of the GFAG array with the same total thickness. For the continuous layer, the DOI resolution, the energy resolution and the timing resolution of the pair of detectors are 4.7 mm, 14% and 402 ps, respectively. Their respective values are 29%, 20% and 33% better than those with the three discrete layers.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1109/TRPMS.2020.3032466","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ieeexplore.ieee.org/document/9233261","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2469-7311","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":"Eiji, Yoshida"}],"nameIdentifiers":[{"nameIdentifier":"1013729","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujino, Obata"}],"nameIdentifiers":[{"nameIdentifier":"1013730","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamada, Kei"}],"nameIdentifiers":[{"nameIdentifier":"1013731","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taiga, Yamaya"}],"nameIdentifiers":[{"nameIdentifier":"1013732","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Eiji, Yoshida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013733","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujino, Obata","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013734","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Taiga, Yamaya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013735","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":"A Crosshair Light Sharing PET Detector With DOI and TOF Capabilities Using Four-to-One Coupling and Single-Ended Readout","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Crosshair Light Sharing PET Detector With DOI and TOF Capabilities Using Four-to-One Coupling and Single-Ended Readout"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-24"},"publish_date":"2021-02-24","publish_status":"0","recid":"81972","relation_version_is_last":true,"title":["A Crosshair Light Sharing PET Detector With DOI and TOF Capabilities Using Four-to-One Coupling and Single-Ended Readout"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:51:13.754911+00:00"}
