In 1998, Digital Imaging Communications in Medicine (DICOM) proposed a calibration tool, the grayscale standard display function (GSDF), to obtain output consistency of radiographs. To our knowledge, there have been no previous reports of investigating the relation between perceptual linearity and detectability on a calibration curve. Materials and methods. To determine a suitable calibration curve for diagnostic liquid crystal display (LCD) monitors, the GSDF and Commission Internationale de l'Eclairage (CIE) curves were compared using psychophysical gradient δ and receiver operating characteristic (ROC) analysis for clinical images. Results. We succeeded in expressing visually recognized contrast directly using δ instead of the just noticeable difference (JND) index of the DICOM standard. As a result, we found that the visually recognized contrast at low luminance areas on the LCD monitor calibrated by the CIE curve is higher than that calibrated by the GSDF curve. On the ROC analysis, there was no significant difference in tumor detectability between GSDF and CIE curves for clinical thoracic images. However, the area parameter Az of the CIE curve is superior to that of the GSDF curve. The detectability of tumor shadows in the thoracic region on clinical images using the CIE curve was superior to that using the GSDF curve owing to the high absolute value of δ in the low luminance range. Conclusion. We conclude that the CIE curve is the most suitable tool for calibrating diagnostic LCD monitors, rather than the GSDF curve. © Japan Radiological Society 2006.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院医学系研究科量子医療技術学","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Verlag"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s11604-006-0085-3","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0288-2043","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uemura, Masanobu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Asai, Yoshiyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Michihiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita, Hideki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shintani, Yuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sanada, Shigeru"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-SANADA-S-653.pdf","filesize":[{"value":"235.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-SANADA-S-653.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/12981/files/ME-PR-SANADA-S-653.pdf"},"version_id":"7c1de0f1-c0df-4566-9ce6-2dcac470e9fd"}]},"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":"Psychophysical evaluation of calibration curve for diagnostic LCD monitor","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Psychophysical evaluation of calibration curve for diagnostic LCD monitor"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"12981","relation_version_is_last":true,"title":["Psychophysical evaluation of calibration curve for diagnostic LCD monitor"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T12:22:40.763945+00:00"}
