Practically, however, it is not easy to do an accurate absorbed dose correction. We made a basic experiment for absorbed dose correction of heterogeneity tissue of lungs using thorax phantom for 10 MV X-rays, and evaluated the accuracy of depth dose calculation algorithms for its tissue which are available in conventional, commercial-based treatment-planning systems. Depth dose on the central axis in lung for small field of 5×5(cm)^2 was reduced by about 10% due to loss of lateral electronic equilibrium. Dose correction factor of heterogeneity was insensitive to the thickness of the build-up layer of this phantom if there was a longitudinal electronic equilibrium. The equivalent TAR (tissue-air ratio) method gave the greatest accuracy for dose calculation algorithms, of lungs whose error was within about 3% compared to the measured values. However, for the smaller field of 5×5(cm)^2, all our methods did not consider the effects of electron scattering, so that the equivalent TAR method and the ratio of TAR method gave errors of about 15% and the power law TAR method about 6%.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"http://ci.nii.ac.jp/naid/110003465509","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人日本放射線技術学会"}]},"item_16_relation_16":{"attribute_name":"情報源(ISSN)","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"03694305"}]}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"公益社団法人日本放射線技術学会"}]},"item_16_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00197784","subitem_source_identifier_type":"NCID"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"492.4","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"493159 bytes"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_text_78":{"attribute_name":"コメント","attribute_value_mlt":[{"subitem_text_value":"本文データは学協会の許諾に基づきCiNiiから複製したものである"},{"subitem_text_value":"荒木不次男\n現：熊本大学医学部保健学科教授（医用画像学）"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"荒木, 不次男"}],"nameIdentifiers":[{"nameIdentifier":"111728","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊谷, 孝三"}],"nameIdentifiers":[{"nameIdentifier":"111729","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-03-02"}],"displaytype":"detail","filename":"110003465509.pdf","filesize":[{"value":"493.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110003465509.pdf","url":"https://kumadai.repo.nii.ac.jp/record/24829/files/110003465509.pdf"},"version_id":"94563652-88ae-41ae-980b-68f56034ee8b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lung correction factor","subitem_subject_scheme":"Other"},{"subitem_subject":"Dose alculation algorithms","subitem_subject_scheme":"Other"},{"subitem_subject":"10 MV X-rays","subitem_subject_scheme":"Other"},{"subitem_subject":"Electronic equilibrium","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":"リニアック 10 MV X 線における肺の線量補正","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"リニアック 10 MV X 線における肺の線量補正"}]},"item_type_id":"16","owner":"1","path":["443"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-06-22"},"publish_date":"2011-06-22","publish_status":"0","recid":"24829","relation_version_is_last":true,"title":["リニアック 10 MV X 線における肺の線量補正"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-09-04T23:52:54.887696+00:00"}
