The PET detectors are placed close to a head to achieve both high sensitivity and high spatial resolution even at the edge of the field of view (FOV). We constructed a new RF-coil for a second prototype of add-on PET, which is combined with 24 DOI-PET detectors and evaluated performance.\n[Methods] The second prototype consisted of an RF-coil and 24 PET detector units with two PET detectors each. The detector units were shielded with carbon fiber shielding boxes. Each PET detector consisted of a 14 x 14 x 4-layer array of lutetium fine silicate (LFS) crystals (1.9 mm x 1.9 mm x 4.0 mm), an 8 x 8 multi-pixel photon counter (MPPC, S12641PA-050) array and a readout circuit board with an ASIC. The RF coil was dedicated to a 3T MRI (MAGNETOM Verio, Siemens). \nIn the evaluation, PET detector performances in simultaneous measurement and spatial resolutions of PET images were measured with a 22Na point-like source and a mini Derenzo phantom. Spin echo (SE) and echo planer imaging (EPI) techniques were used in the evaluation experiment of the simultaneous measurements. \n[Results] The influence of the simultaneous measurements with MRI on the PET performance was negligible. All of 1.6 mm hot rods were distinguished in the phantom ezperiment. \n[Conclusion] The influence of the simultaneous measurements with MRI on the PET performance was negligible. In addition, the superior spatial resolution of the PET images was obtained.","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":"第113回医学物理学会学術大会","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":"錦戸, 文彦"}],"nameIdentifiers":[{"nameIdentifier":"652587","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤原, 理伯"}],"nameIdentifiers":[{"nameIdentifier":"652588","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩男, 悠真"}],"nameIdentifiers":[{"nameIdentifier":"652589","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島, 英朗"}],"nameIdentifiers":[{"nameIdentifier":"652590","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田, 英治"}],"nameIdentifiers":[{"nameIdentifier":"652591","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅, 幹生"}],"nameIdentifiers":[{"nameIdentifier":"652592","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"清水, 啓司"}],"nameIdentifiers":[{"nameIdentifier":"652593","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小畠, 隆行"}],"nameIdentifiers":[{"nameIdentifier":"652594","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷, 泰賀"}],"nameIdentifiers":[{"nameIdentifier":"652595","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤原 理伯","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652597","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩男 悠真","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652598","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島 英朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652599","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652600","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅 幹生","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652601","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小畠 隆行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652602","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"652603","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"Development of second add-on PET/MRI prototype: Evaluation of PET imaging performance","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of second add-on PET/MRI prototype: Evaluation of PET imaging performance"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-18"},"publish_date":"2017-05-18","publish_status":"0","recid":"66324","relation_version_is_last":true,"title":["Development of second add-on PET/MRI prototype: Evaluation of PET imaging performance"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:50:13.112500+00:00"}
