In this respect there are few studies using both filtered back projection (FBP) and ordered subsets expectation maximization (OSEM) methods for the digital phantom.\nFirst we reconstructed the SPECT images by FBP and OSEM for the digital phantom.  The present study was made for (1) cutoff frequencies by　different pre-treatment filtering, (2) partial volume effects, (3) spatial resolution by different collimators, and (4) evaluation of spatial resolution by different rotary radii. We made the above evaluations by making visual evaluation, conducting measurement of counts, and calculating full width at half maximum (FWHM) and normalized mean square error (NMSE). \nAs a result, (1) by visual evaluation, OSEM images were stable.  (2) OSEM showed lower values in the optimal cutoff frequency using NMSE.  (3) The digital phantom for physical performance evaluation showed clearer, partial volume effect.  (4) FWHM showed slightly lower values in FBP images.  These results were found to correspond well with those of phantom experiments using radiopharmaceuticals and those of clinical SPECT images.\nFrom the above findings, it was suggested that the digital phantom was considerably excellent in deepening the understanding of the effect of SPECT image reconstruction by FBP and OSEM on the image quality.\n","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"純真学園大学"}]},"item_10002_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40020087092","subitem_relation_type_select":"NAID"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12581584","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2186-6481","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KAWAMURA, Seiji"},{"creatorName":"KAWAMURA, Seiji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"144","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000250171749","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000250171749"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-11"}],"displaytype":"detail","filename":"純真学園大学雑誌-03号_p091-097.pdf","filesize":[{"value":"962.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"純真学園大学雑誌-03号_p091-097","url":"https://junshin.repo.nii.ac.jp/record/94/files/純真学園大学雑誌-03号_p091-097.pdf"},"version_id":"f78e8736-6c96-4671-9ea3-3d45d121d339"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"OSEM","subitem_subject_scheme":"Other"},{"subitem_subject":"MLEM","subitem_subject_scheme":"Other"},{"subitem_subject":"FBP","subitem_subject_scheme":"Other"},{"subitem_subject":"subset","subitem_subject_scheme":"Other"},{"subitem_subject":"iteration","subitem_subject_scheme":"Other"},{"subitem_subject":"NMSE","subitem_subject_scheme":"Other"},{"subitem_subject":"OSEM","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MLEM","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"FBP","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"subset","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"iteration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"NMSE","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Fundamental Examination of SPECT Images using Digital Phantom for Physical Performance Evaluation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fundamental Examination of SPECT Images using Digital Phantom for Physical Performance Evaluation"},{"subitem_title":"Fundamental Examination of SPECT Images using Digital Phantom for Physical Performance Evaluation","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["15"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-11"},"publish_date":"2016-10-11","publish_status":"0","recid":"94","relation_version_is_last":true,"title":["Fundamental Examination of SPECT Images using Digital Phantom for Physical Performance Evaluation"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2023-05-15T15:41:55.179401+00:00"}
