The X'tal cube is based on a segmented 3D crystal block for which all surfaces are covered with photo-detectors. We have shown that the X'tal cube can achieve isotropic intrinsic resolution with the Anger-type calculation even at the block edges. In this work, we developed a new one pair prototype system to simulate a ring-type scanner, and evaluated imaging performance of the X'tal cube detector.\nMethods: The developed system consisted of two X'tal cube detectors, two rotating stages, and a 192-channel data acquisition system. The X'tal cube consisted of the LYSO cubic crystal block of (18 mm)3 in which the 3D grids of 2 mm pitch were fabricated by the internal laser processing. 4 x 4 arrays of multi pixel photon counters (MPPCs) were optically coupled to each surface of the crystal block. The detector positions were automatically controlled to simulate a ring-type PET of 14.6 cm in diameter. Data were collected for assumed all detector positions and then a sinogram was obtained. The data were reconstructed using the filtered backprojection.\nResults: We successfully obtained uniform spatial resolution less than 2 mm over the FOV. \nConclusion: We developed one pair prototype system for the X'tal cube detector, and we confirmed its potential for high-resolution imaging","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":"SNM2012　Annual Meeting","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":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"637038","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirano, Yoshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"637039","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tashima, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"637040","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Mitsuo"}],"nameIdentifiers":[{"nameIdentifier":"637041","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"637042","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"637043","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"637044","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"637045","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637046","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平野 祥之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637047","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島 英朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637048","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637049","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637050","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637051","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"637052","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":"Impact of the X'tal cube detector with isotropic resolution on imaging resolution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Impact of the X'tal cube detector with isotropic resolution on imaging resolution"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-06-28"},"publish_date":"2012-06-28","publish_status":"0","recid":"64643","relation_version_is_last":true,"title":["Impact of the X'tal cube detector with isotropic resolution on imaging resolution"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:09:17.018156+00:00"}
