We approximated body tissues to binary mixtures out of muscle, air, fat, and bone. Consequently, the relationship can be calibrated only with a CT scan of their substitutes, for which we chose water, air, ethanol, and potassium phosphate solution, respectively. With simple and specific corrections for non-equivalencies of the substitutes, the calibration accuracy of 1% will be achieved. The proposed method would offer accuracy, simplicity, and specificity required for a standard in radiotherapy treatment planning, in particular, with heavy charged particles.","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":"14th International Conference on the Use of Computers in Radiation Therapy","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":"Kanematsu, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"599645","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsufuji, Naruhiro"}],"nameIdentifiers":[{"nameIdentifier":"599646","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kohno, Ryosuke"}],"nameIdentifiers":[{"nameIdentifier":"599647","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Minohara, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"599648","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanai, Tatsuaki"}],"nameIdentifiers":[{"nameIdentifier":"599649","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼松 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"599650","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松藤 成弘","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"599651","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河野 良介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"599652","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"蓑原 伸一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"599653","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金井 達明","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"599654","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":"A simple and accurate CT number to density calibration method for radiotherapy treatment planning","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A simple and accurate CT number to density calibration method for radiotherapy treatment planning"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-05-17"},"publish_date":"2004-05-17","publish_status":"0","recid":"60381","relation_version_is_last":true,"title":["A simple and accurate CT number to density calibration method for radiotherapy treatment planning"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:54:23.759887+00:00"}
