Linear energy transfer (LET) of energy scanning, accuracy of spot depth, position, and dose were evaluated using an in-house built jig.\n Imobilization devices, position confirmation and beam control systems were also checked for treatment.\nResults\n Evaluation of dose distribution showed improvement in doses to risk tissues compared to passive scattering beams, but with higher maximum dose. The higher maximum dose was evaluated clinically insignificant.\n Lower LET was observed in energy scanning. Dose converting for lower energies were offset by XX%. Spot position accuracy was obtained by using rescanning techniques.\n Imobilization devices were confirmed to fit in the new treatment room. Position confirmation was possible using a head phantom. Patient monitoring and beam control systems functioned properly with minor modifications. \nConclusion\n Energy scanning with the rotating gantry showed to be equal to superior compared to passive scattering. We have successfully constructed a workflow for QA / QC and is ready for clinical application.","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":"H29年度HIMAC共同利用研究成果発表会","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":"牧島, 弘和"}],"nameIdentifiers":[{"nameIdentifier":"656888","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻, 比呂志"}],"nameIdentifiers":[{"nameIdentifier":"656889","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"粕谷, 吾朗"}],"nameIdentifiers":[{"nameIdentifier":"656890","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"早乙女, 直也"}],"nameIdentifiers":[{"nameIdentifier":"656891","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂間, 誠"}],"nameIdentifiers":[{"nameIdentifier":"656892","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"米内, 俊介"}],"nameIdentifiers":[{"nameIdentifier":"656893","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼松, 伸幸"}],"nameIdentifiers":[{"nameIdentifier":"656894","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田, 正"}],"nameIdentifiers":[{"nameIdentifier":"656895","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"牧島 弘和","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656896","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻 比呂志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656897","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"粕谷 吾朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656898","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"早乙女 直也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656899","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂間 誠","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656900","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼松 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656901","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田 正","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656902","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"脈絡膜悪性黒色腫における回転ガントリーの有用性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"脈絡膜悪性黒色腫における回転ガントリーの有用性に関する研究"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-11"},"publish_date":"2018-05-11","publish_status":"0","recid":"66808","relation_version_is_last":true,"title":["脈絡膜悪性黒色腫における回転ガントリーの有用性に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:44:40.675527+00:00"}
