K-edge subtraction (KES) technique is a new technique for identifying a low-density material. This technique is needed to a large difference of attenuation coefficients for a target material, that is seen in two energy regions on little-lower and little-higher energy for K-absorption edge of a target material. By imaging of those different attenuation, the KES technique shows the image of only target material by subtracting between two images obtained by x rays with lower and higher energies than K-edge energy. Then, we attempted a diffraction method for generating monochromatic x rays with special energy sift. The diffracted monochromatic x rays are produced by Bragg diffraction on a silicon single crystal and are imaged as Laue spot on the reflected position. If the incident x rays are completely parallel, the Laue spot is imaged by a single energy of diffracted x rays. However, x rays irradiated from an x-ray tube are shaped as a conically cone beam. Therefore, depending on the angles between the cone-beamed x rays and a silicon atomic layer, the spatial energy shift are shown on the Laue spot. Moreover, in case of acquitting high-energy monochromatic diffracted x rays, diffracted and translated x rays are closed a distance. In this study, we focused on the Nth-harmonic diffraction and tried to obtain platinum K-absorption edge images.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者（英）","attribute_value_mlt":[{"names":[{"name":"Yokote, Hiroki","nameLang":"en"}]},{"names":[{"name":"Yoshimura, Kanata","nameLang":"en"}]},{"names":[{"name":"Maeda, Koji","nameLang":"en"}]}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.60172/00000326","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"広島国際大学大学院医療・福祉学研究科"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-9265","subitem_source_identifier_type":"PISSN"}]},"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":"横手, 大輝","creatorNameLang":"ja"},{"creatorName":"ヨコテ, ヒロキ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"吉村, 哉汰","creatorNameLang":"ja"},{"creatorName":"ヨシムラ, カナタ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"前田, 浩志","creatorNameLang":"ja"},{"creatorName":"マエダ, コウジ","creatorNameLang":"ja-Kana"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-11"}],"displaytype":"detail","filename":"jme16_019.pdf","filesize":[{"value":"3.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jme16_019.pdf","url":"https://hirokoku-u.repo.nii.ac.jp/record/332/files/jme16_019.pdf"},"version_id":"aeb15612-52b5-49c2-829c-9fbeb8916ad0"}]},"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":"空間的エネルギー変化を有するn次高調波回折X線のスペクトル評価およびK吸収端画像の取得","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"空間的エネルギー変化を有するn次高調波回折X線のスペクトル評価およびK吸収端画像の取得","subitem_title_language":"ja"},{"subitem_title":"Evaluation of x-ray spectra and K-absorpotion edge images for Nth-harmonic diffracted x rays with spatial energy shift","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"4","path":["71"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-11"},"publish_date":"2023-03-11","publish_status":"0","recid":"332","relation_version_is_last":true,"title":["空間的エネルギー変化を有するn次高調波回折X線のスペクトル評価およびK吸収端画像の取得"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2024-02-05T04:04:31.742835+00:00"}
