Registration of anatomical structures between the site of beam entrance on the patient surface and the distal target position is particularly important. Here, to improve patient positional accuracy during set-up for particle beam treatment, we propose a new visualization methodology using digitally reconstructed radiographs (DRRs), overlaid DRRs, and evaluation of overlaid DRR images in clinical cases. The overlaid method overlays two DRR images in different colors by dividing the CT image into two CT sections at the distal edge of the target along the treatment beam direction. Since our hospital uses fixed beam ports, the treatment beam angles for this study were set at 0 and 90 degrees. The DRR calculation direction was from the X-ray tube to the imaging device, and set to 180/270 degrees and 135/225 degrees, based on the installation of our X-ray imaging system. Original and overlaid DRRs were calculated using CT data for two patients, one with a parotid gland tumor and the other with prostate cancer. The original and overlaid DRR images were compared. Since the overlaid DRR image was completely separated into two regions when the DRR calculation angle was the same as the treatment beam angle, the overlaid DRR visualization technique was able to provide rich information for aiding recognition of the relationship between anatomical structures and the target position. This method will also be useful in patient set-up procedures for fixed irradiation ports.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Oxford University Press"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"25678537","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1093/jrr/rrv002","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0449-3060","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":"Yoshino, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"486790","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miki, Kentaro"}],"nameIdentifiers":[{"nameIdentifier":"486791","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakata, Kozo"}],"nameIdentifiers":[{"nameIdentifier":"486792","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakayama, Yuko"}],"nameIdentifiers":[{"nameIdentifier":"486793","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibayama, Kouichi"}],"nameIdentifiers":[{"nameIdentifier":"486794","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mori, Shinichiro"}],"nameIdentifiers":[{"nameIdentifier":"486795","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉野 慎一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"486796","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三木 健太朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"486797","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中山 優子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"486798","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"柴山 晃一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"486799","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 慎一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"486800","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":"Digital reconstructed radiography with multiple color image overlay for image-guided radiotherapy.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Digital reconstructed radiography with multiple color image overlay for image-guided radiotherapy."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-11"},"publish_date":"2018-01-11","publish_status":"0","recid":"48427","relation_version_is_last":true,"title":["Digital reconstructed radiography with multiple color image overlay for image-guided radiotherapy."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:28:13.723786+00:00"}
