Better scanner sensitivity enables not only quantitative imaging but also shorter scan time, reduced radiation dose and shorter time-frame intervals. In conventional PET scanners, however, detectors which are arranged closer to the field-of-view (FOV) degrade the peripheral spatial resolution due to the parallax error. Some research groups have concentrated on depth-of-interaction (DOI) measurement, which suppresses the parallax error. Among them, dual layer DOI detectors based on the pulse shape discrimination of two types of crystals have been developed and practically installed in a human brain PET scanner and small animal PET scanners. \nIn order to achieve not only higher spatial resolution but also higher scanner sensitivity, we have proposed a novel detector which provides 4-layer DOI information of multi-layered thin crystals based on the coded reflector insertion, and we are developing a prototype scanner, jPET-D4. At this stage, we have developed a full-ring prototype scanner and 3D image reconstruction software. \nIn this work, we present imaging performance of the jPET-D4 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":"The 11th Conference of Peace through Mind / Brain Science","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":"701737","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"701738","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":"Image Reconstruction of the jPET-D4: A Novel 4-Layer Depth-of-Interaction PET Scanner","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Image Reconstruction of the jPET-D4: A Novel 4-Layer Depth-of-Interaction PET Scanner"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-11-18"},"publish_date":"2013-11-18","publish_status":"0","recid":"71367","relation_version_is_last":true,"title":["Image Reconstruction of the jPET-D4: A Novel 4-Layer Depth-of-Interaction PET Scanner"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:52:04.436111+00:00"}
