However, the results are not immediately available, it takes from several hours to 24 h, and expensive. We aimed to develop a novel film with diarylethene (DAE) as one of photochromic molecules, which could visualize the radiation dose by chemical reaction, to overcome the disadvantages of the RCF. The DAE film was found to achieve the sensitivity to the kV X-ray with a range suitable for clinical uses. It can be analyzed immediately after irradiation. It is anticipated the DAE film can be used in clinical practice, such as radiation diagnostics and brachytherapy, employing either kV X-rays or γ-rays. For MV X-ray and electron beams used in radiotherapy, the DAE film could not achieve the sensitivity to those radiation, while it was found that the liquid DAE could have the sensitivity to the radiation dose.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：若手研究; 研究期間：2019～2021; 課題番号：19K17213; 研究分野：医学物理, 放射線技術学; 科研費の分化・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tamura, Mikoto"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学医学部; 助教"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田村, 命"},{"creatorName":"タムラ, ミコト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43223","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60810968","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=60810968"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-05"}],"displaytype":"detail","filename":"19K17213seika.pdf","filesize":[{"value":"635.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19K17213seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23284/files/19K17213seika.pdf"},"version_id":"4339a458-19ac-4c20-a7d7-2b08941c730e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"フォトクロミック化合物","subitem_subject_scheme":"Other"},{"subitem_subject":"ジアリールエテン","subitem_subject_scheme":"Other"},{"subitem_subject":"医用放射線","subitem_subject_scheme":"Other"},{"subitem_subject":"放射線線量計","subitem_subject_scheme":"Other"},{"subitem_subject":"フィルム線量測定","subitem_subject_scheme":"Other"},{"subitem_subject":"X線","subitem_subject_scheme":"Other"},{"subitem_subject":"電子線","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"フォトクロミックフィルム放射線線量計の開発と医療応用への実践","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フォトクロミックフィルム放射線線量計の開発と医療応用への実践","subitem_title_language":"ja"},{"subitem_title":"Development of a novel photochromic dosimetry film","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4819"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-05"},"publish_date":"2022-12-05","publish_status":"0","recid":"23284","relation_version_is_last":true,"title":["フォトクロミックフィルム放射線線量計の開発と医療応用への実践"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-02T01:01:33.836410+00:00"}
