In 2010, the audit for the non-reference condition including field size change or wedge insertion was initiated. This study summarizes the latest results of non-reference condition.\nMethods\n Through these 4 years, 458 beams have been measured for different field size from 5 x 5 cm2 to 25 x 25 cm2 and 301 beams have been measured for different wedge angle from 15 to 60 degrees.\nResults\n For the beams with the field size change, the mean differences of measured from stated dose at each field size, 5 x 5 (n = 197), 15 x 15 (n = 55), 20 x 20 (n = 173), and 25 x 25 (n =33) cm2, were -0.3%, 0.3%, 0.4%, and 0.2% respectively. The standard deviations of the distribution at each field size were 1.0%, 1.0%, 1.2%, and 1.5% respectively. For the wedged beam irradiation, the mean of the differences of measured from stated dose with each wedge angles, 15° (n = 112), 30° (n = 102), 45° (n = 45), and 60° (n = 42), were 0.1%, 0.1%, 0.1%, and 0.3% respectively. The standard deviations of the distribution at each wedged angle were 1.0%, 1.3%, 1.2%, and 1.3% respectively. \nConclusion\n The postal dose audit using RGD to non-reference condition has been successfully performed. The mean differences of measured from stated dose were within 0.5% for every field size and wedge angle.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The 7th Korea-Japan Joint Meeting on Medical Physics","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mizuno, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"703089","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamashita, Wataru"}],"nameIdentifiers":[{"nameIdentifier":"703090","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takase, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"703091","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakata, Suho"}],"nameIdentifiers":[{"nameIdentifier":"703092","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukahori, Mai"}],"nameIdentifiers":[{"nameIdentifier":"703093","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukumura, Akifumi"}],"nameIdentifiers":[{"nameIdentifier":"703094","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"水野 秀之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703095","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山下 航","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703096","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高瀬 信宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703097","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐方 周防","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703098","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"深堀 麻衣","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703099","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福村 明史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703100","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Recent results of a postal dose audit for radiotherapy machine in Japan with non-reference condition","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Recent results of a postal dose audit for radiotherapy machine in Japan with non-reference condition"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-30"},"publish_date":"2014-09-30","publish_status":"0","recid":"71504","relation_version_is_last":true,"title":["Recent results of a postal dose audit for radiotherapy machine in Japan with non-reference condition"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:50:29.388663+00:00"}
