Determination of the characteristic curve is essential for a quantitative evaluation of radiography as is X-ray film radiographic imaging process. Plotting the density measured against the log of exposure given makes a typical X-ray film characteristic curve. The shape of the curve represents the contrast response of the X-ray film to a wide range of exposures. When it is not practical to generate the entire\ncurve through a variation of a single exposure parameter, bootstrap methods can be used. For the bootstrap method used here, a three-exposure parameter (X-ray radiation time：1min, 2min, 3min) generates curve segments.\n In this study the characteristic curves of a mammography film (UM-MA HC, AD-M) and IX-FR film are compared. As a result, fine density was obtained for UM-MA HC in irradiation time of 1 min and for IX-FR in irradiation time of 3 min. The authors conclude that UN-MA HC provides a wide range of characteristics in a short time. However, it is known that the density of the image increases with the energy of radiation and IX-FR usually has more density than UM-MA HC. Therefore, the subject and the type of investigation should influence the choice of film.","subitem_description_type":"Abstract"}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18953/00003685","subitem_identifier_reg_type":"JaLC"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松島, 朝秀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三浦, 定俊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomohide, MATSUSHIMA","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sadatoshi, MIURA","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-07-31"}],"displaytype":"detail","filename":"04609.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"04609.pdf","url":"https://tobunken.repo.nii.ac.jp/record/3695/files/04609.pdf"},"version_id":"bcdd51c9-23d2-47d9-9ed1-9af1fe1ef766"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"X線フィルム","subitem_subject_scheme":"Other"},{"subitem_subject":"特性曲線","subitem_subject_scheme":"Other"},{"subitem_subject":"マンモグラフィ","subitem_subject_scheme":"Other"},{"subitem_subject":"透過X線撮影","subitem_subject_scheme":"Other"},{"subitem_subject":"Radiography; X-ray film; Mammography; Characteristic Curve","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"〔報文〕文化財の透過X線撮影におけるマンモグラフィ用フィルムの特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"〔報文〕文化財の透過X線撮影におけるマンモグラフィ用フィルムの特性"},{"subitem_title":"Comparison of the Characteristic Curves of a Mammography Film and an IX-FR Film in Radiography","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["520"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-31"},"publish_date":"2017-07-31","publish_status":"0","recid":"3695","relation_version_is_last":true,"title":["〔報文〕文化財の透過X線撮影におけるマンモグラフィ用フィルムの特性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T15:20:45.254426+00:00"}
