The evaluation metrics were calculation speed and image quality with various slice thicknesses. The results showed that GPU-based DRR computation was an average of 50 times faster than the CPU-based methodology, whereas the image quality was very similar. This excellent performance may increase the accuracy of patient positioning and improve the patient treatment-throughput time.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1865-0333","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":"Mori, Shinichiro"}],"nameIdentifiers":[{"nameIdentifier":"451067","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Masanao"}],"nameIdentifiers":[{"nameIdentifier":"451068","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kumagai, Motoki"}],"nameIdentifiers":[{"nameIdentifier":"451069","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Minohara, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"451070","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森 慎一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"451071","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林 正直","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"451072","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊谷 始紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"451073","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":"Development of GPU-based Multi-threaded Software Application to Calculate Digitally Reconstructed Radiographs for Radiotherapy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of GPU-based Multi-threaded Software Application to Calculate Digitally Reconstructed Radiographs for Radiotherapy"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-02-02"},"publish_date":"2009-02-02","publish_status":"0","recid":"45412","relation_version_is_last":true,"title":["Development of GPU-based Multi-threaded Software Application to Calculate Digitally Reconstructed Radiographs for Radiotherapy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:04:02.090702+00:00"}
