However, in this paper we propose improving the time-domain response of a conventional thermistor using a signal processing technique composed of a series of first-order high-pass filters which is known as the natural observation system. We considered the rise time of the thermistor in response to a step temperature change to effect correction for the measurement of the ejection fraction. The coefficients of the natural observation system were calculated by minimizing the square error between the step-response signal of the thermistor and the band-limited reference signal. In an experiment using a model ventricle, the thermodilution curve obtained from a conventional thermistor was improved using the proposed technique, thus enabling successful measurement of the ejection fraction of the ventricles.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/trans_online/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110003215808","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyright@1994 IEICE"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826239","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168508","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hori, Jun'ichi"}],"nameIdentifiers":[{"nameIdentifier":"6251","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saitoh, Yoshiaki"}],"nameIdentifiers":[{"nameIdentifier":"6252","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kiryu, Tohru"}],"nameIdentifiers":[{"nameIdentifier":"6253","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"110003215808.pdf","filesize":[{"value":"989.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110003215808.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1924/files/110003215808.pdf"},"version_id":"63fa0405-147f-4cfd-98a0-9740a6580054"}]},"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":"Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)"},{"subitem_title":"Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-24"},"publish_date":"2012-10-24","publish_status":"0","recid":"1924","relation_version_is_last":true,"title":["Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:45.052569+00:00"}
