However, the measured histogram is affected by inter-crystal scatterings (ICS) which occur in a whole detector. Peaks with projected each crystal in the histogram are blurred, and it causes ICS's mispositioning. A depth of interaction (DOI) detector has been developed for the small animal PET scanner: jPET-RD. This DOI detector uses 32 x 32 crystals with four layers and a 256-channel multi-anode flat panel photomultiplier tube (FP-PMT) was developed by Hamamatsu Photonics K.K. Each crystal element is 1.45 x 1.45 x 4.5 mm3. The FP-PMT has a large detective area (49 x 49 mm2) and small anode pitch (3.04 mm). Therefore, the FP-PMT can extensively trace the behavior of incident gamma rays in the crystals including ICS. We therefore propose a novel method for ICS estimation using a statistical pattern recognition based on the support vector machine (SVM). In this study, we applied the SVM for discriminating photoelectric events from ICS events generated from multiple-anode outputs. The SVM was trained by uniform irradiation events generated from a detector simulator using Monte Carlo calculation. Initial result of ICS identification is about 78 % for non-training data. This method can archive a true subtraction of ICS from measured events, and it is also useful for random correction in 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":"1st European Conference on Molecular Imaging Technology","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":"673477","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Keishi"}],"nameIdentifiers":[{"nameIdentifier":"673478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kimura, Yuichi"}],"nameIdentifiers":[{"nameIdentifier":"673479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"673480","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Kengo"}],"nameIdentifiers":[{"nameIdentifier":"673481","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"673482","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"673483","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673484","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 圭司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673485","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木村 裕一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673486","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673487","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"澁谷 憲悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673488","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673490","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":"Inter-crystal scatter identification for a depth-sensitive detector using support vector machine for small animal PET","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Inter-crystal scatter identification for a depth-sensitive detector using support vector machine for small animal PET"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-08-18"},"publish_date":"2006-08-18","publish_status":"0","recid":"68625","relation_version_is_last":true,"title":["Inter-crystal scatter identification for a depth-sensitive detector using support vector machine for small animal PET"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:24:02.515000+00:00"}
