We introduce a light output correction procedure to compensate for variations among the crystal elements in the DOI detector. Under uniform irradiation with 511 keV gamma rays, we estimate the light output of each crystal element by identifying each crystal, and generate a look-up table (LUT) for light output correction. The variation of light output of each crystal element is 18%. We evaluate the energy resolution of all crystal elements. The energy resolution before light output correction was 40%. Using DOI information, an energy resolution of 18% has been achieved after light output correction. We present and analyze the crystal position dependence of energy spectra due to inter-crystal scattering among the multiple crystal elements in the DOI detector.","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":"Medical Image Conference","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":"667085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"667086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 英治","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"667087","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":"Energy spectra and their calibration of four-layer DOI detector for brain PET scanner: jPET-D4","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Energy spectra and their calibration of four-layer DOI detector for brain PET scanner: jPET-D4"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-10-29"},"publish_date":"2004-10-29","publish_status":"0","recid":"67917","relation_version_is_last":true,"title":["Energy spectra and their calibration of four-layer DOI detector for brain PET scanner: jPET-D4"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:32:13.800452+00:00"}
