Originally, our design consisted of a crystal block for which all six surfaces were covered with arrays of multi-pixel photon counters (MPPCs). In this paper, we examined the feasibility of reducing the number of surfaces on which a MPPC array must be connected with the aim of reducing the complexity of the system. We evaluated two kinds of laser-processed X'tal cubes of 3 mm and 2 mm pitch segments while varying the numbers of the 4 * 4 MPPC arrays down to two surfaces. The sub-surface laser engraving technique was used to fabricate 3D grids into a monolithic crystal block. The 3D flood histograms were obtained by the Anger-type calculation. Two figures of merit, peak-to-valley ratios and distance-to-width ratios, were used to evaluate crystal identification performance. Clear separation was obtained even in the 2-surface configuration for the 3 mm X'tal cube, and the average peak-to-valley ratios and the distance-to-width ratios were 6.7 and 2.6, respectively. Meanwhile, in the 2 mm X'tal cube, the 6-surface configuration could separate all crystals and even the 2-surface case could also, but the flood histograms were relatively shrunk in the 2-surface case, especially on planes parallel to the sensitive surfaces. However, the minimum peak-to-valley ratio did not fall below 3.9. We concluded that reducing the numbers of MPPC readout surfaces was feasible for both the 3 mm and the 2 mm X'tal cubes.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/0031-9155/58/5/1361","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-9155","subitem_source_identifier_type":"ISSN"}]},"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":"Hirano, Yoshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"465218","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inadama, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"465219","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Eiji"}],"nameIdentifiers":[{"nameIdentifier":"465220","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikido, Fumihiko"}],"nameIdentifiers":[{"nameIdentifier":"465221","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Hideo"}],"nameIdentifiers":[{"nameIdentifier":"465222","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Mitsuo"}],"nameIdentifiers":[{"nameIdentifier":"465223","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaya, Taiga"}],"nameIdentifiers":[{"nameIdentifier":"465224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平野 祥之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"稲玉 直子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465227","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸 文彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465228","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村山 秀雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山谷 泰賀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465230","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Potential for reducing the numbers of SiPM readout surfaces of laser-processed X'tal cube PET detectors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Potential for reducing the numbers of SiPM readout surfaces of laser-processed X'tal cube PET detectors"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-12-06"},"publish_date":"2013-12-06","publish_status":"0","recid":"46665","relation_version_is_last":true,"title":["Potential for reducing the numbers of SiPM readout surfaces of laser-processed X'tal cube PET detectors"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:49:04.302666+00:00"}
