There are no reflectors within the block, and the areas among MPPCs on the surface are covered with reflector. Each MPPC is thin and light solid-state photo-detector so that the crystal block can be closely placed on the PET detector ring.\n To study the characteristics of the Xtal cube, we constructed a crystal block consisting of six layers of a 6 x 6 segmented crystal array with Lu2xGd2(1-x)SiO5 (LGSO) crystals. Each crystal is 3.0 x 3.0 x 3.0 mm3. We examined crystal identification performance for different MPPC arrangements on the block surfaces, where we used 3-dimensional (3D) Anger-type position calculation. The preliminary experiments showed the possibility of a 3D detector having isotropic resolutions for PET.","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":"2009 IEEE 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":"Yazaki, Yujiro"}],"nameIdentifiers":[{"nameIdentifier":"686568","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"686569","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"矢崎 祐次郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"686570","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":"The Xtal Cube PET Detector: 3D Scintillation Photon Detection by a 3D Crystal Array Using MPPCs","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Xtal Cube PET Detector: 3D Scintillation Photon Detection by a 3D Crystal Array Using MPPCs"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-05"},"publish_date":"2009-11-05","publish_status":"0","recid":"69921","relation_version_is_last":true,"title":["The Xtal Cube PET Detector: 3D Scintillation Photon Detection by a 3D Crystal Array Using MPPCs"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:08:53.738853+00:00"}
