One of our targets is in-beam PET, which is a method for <i>in situ</i> monitoring of charged particle therapy. In our initial idea, the OpenPET had a physically opened field-of-view (FOV) between two detector rings separated by a gap. Originally, the OpenPET was proposed to provide a stress-less brain imaging device. For a dedicated in-beam PET scanner, this dual-ring OpenPET is a good candidate, but it is not necessarily the most efficient geometry because it has a wide FOV (i.e., a gap FOV plus two in-ring FOVs) while only a limited FOV around the irradiation field is required in actual use of in-beam PET. At the last conference, therefore, we proposed a single-ring OpenPET (SROP) dedicated for in-beam PET as our 2<sup>nd</sup> generation geometry. The detector ring of the SROP geometry was the cylinder both ends of which were cut by parallel aslant planes. In this paper, we developed a small prototype of the SROP for a proof-of-concept. It consisted of 2 ellipse-shaped detector rings, each of which had 16 detectors. Each ellipse-shaped detector ring had a major axis of 281.6 mm and a minor axis of 207.5 mm. The rings were slanted by 45 deg and staggered to obtain an open space of 74.5 mm width. We carried out initial in-beam imaging tests in the Heavy Ion Medical Accelerator in Chiba (HIMAC) using a <sup>11</sup>C beam as well as a <sup>12</sup>C beam. PET measurement started at the beginning of the irradiation, and continued for 20 min after the irradiation. For about 3Gy irradiation, a 6 mm range difference was clearly detected with the <sup>11</sup>C beam irradiation. Our initial imaging studies showed promising performance of the SROP prototype.","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":"2012IEEE NSS&MIC","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":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"638910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"638911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kinouchi, Shoko"}],"nameIdentifiers":[{"nameIdentifier":"638912","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Yasunori"}],"nameIdentifiers":[{"nameIdentifier":"638913","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"638914","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirano, Yoshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"638915","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tashima, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"638916","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"638917","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suga, Mikio"}],"nameIdentifiers":[{"nameIdentifier":"638918","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Haneishi, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"638919","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satou, Shinji"}],"nameIdentifiers":[{"nameIdentifier":"638920","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inaniwa, Taku"}],"nameIdentifiers":[{"nameIdentifier":"638921","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638922","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638923","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木内 尚子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638924","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中島 靖紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638925","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638926","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平野 祥之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638927","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田島 英朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤 浩","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅 幹生","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638930","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽石 秀昭","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638931","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤 眞二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638932","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲庭 拓","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"638933","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":"A small prototype of a single-ring OpenPET","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A small prototype of a single-ring OpenPET"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-11-13"},"publish_date":"2012-11-13","publish_status":"0","recid":"64835","relation_version_is_last":true,"title":["A small prototype of a single-ring OpenPET"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:07:04.327552+00:00"}
