The experiment was repeated with\nall most common radiation treatment types (photons, protons and carbon ions) and delivery techniques\n(Intensity Modulated Radiation Therapy, passive modulation and spot scanning). The measurements\nwere performed with active diamond detector and passive thermoluminescence (TLD) detectors to investigate the out-of-field dose both inside and outside the phantom.\nResults: The highest out-of-field dose values both on the surface and inside the phantom were measured\nduring the treatment with 25 MV photons. In the proximity of the Planned Target Volume (PTV), the lowest lateral dose profile was observed for passively modulated protons mainly because of the presence of\nthe collimator in combination with the chosen volume shape. In the far out-of-field region (above\n100 mm from the PTV), passively modulated ions were characterized by a less pronounced dose falloff in comparison with scanned beams. Overall, the treatment with scanned carbon ions delivered the\nlowest dose outside the target volume.\nConclusions: For the selected PTV, the use of the collimator in proton therapy drastically reduced the dose\ndeposited by ions or photons nearby the tumor. Scanning modulation represents the optimal technique\nfor achieving the highest dose reduction far-out-of-field.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.radonc.2012.04.004","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0167-8140","subitem_source_identifier_type":"ISSN"}]},"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":"Latessa, Chiara"}],"nameIdentifiers":[{"nameIdentifier":"464909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Berger, Thomas"}],"nameIdentifiers":[{"nameIdentifier":"464910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kaderka, Robert"}],"nameIdentifiers":[{"nameIdentifier":"464911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsufuji, Naruhiro"}],"nameIdentifiers":[{"nameIdentifier":"464912","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Reitz, Gunther"}],"nameIdentifiers":[{"nameIdentifier":"464913","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Durante, Marco"}],"nameIdentifiers":[{"nameIdentifier":"464914","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"464915","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｌａｔｅｓｓａ Ｃｈｉａｒａ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464916","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｋａｄｅｒｋａ Ｒｏｂｅｒｔ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464917","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松藤 成弘","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464918","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Out-of-field dose studies with an anthropomorphic phantom: comparison of X-rays and particle therapy treatments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Out-of-field dose studies with an anthropomorphic phantom: comparison of X-rays and particle therapy treatments"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-11-26"},"publish_date":"2013-11-26","publish_status":"0","recid":"46633","relation_version_is_last":true,"title":["Out-of-field dose studies with an anthropomorphic phantom: comparison of X-rays and particle therapy treatments"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:49:26.898189+00:00"}
