Methods: To assess the actual TR of helical acquisition modes of a 128-slice dual source CT (DSCT) scanner and a 320-row area detector CT (ADCT) scanner, we assessed the TRs of various acquisition combinations of a pitch factor (P) and gantry rotation time (R). Results: The TR of the helical acquisition modes for the 128-slice DSCT scanner continuously improved with a shorter gantry rotation time and greater pitch factor. However, for the 320-row ADCT scanner, the TR with a pitch factor of <1.0 was almost equal to the gantry rotation time, whereas with pitch factor of >1.0, it was approximately one half of the gantry rotation time. The maximum TR values of single- and dual-source helical acquisition modes for the 128-slice DSCT scanner were 0.138 (R/. P = 0.285/1.5) and 0.074. s (R/. P = 0.285/3.2), and the maximum TR values of the 64. ×. 0.5- and 160. ×. 0.5-mm detector configurations of the helical acquisition modes for the 320-row ADCT scanner were 0.120 (R/. P = 0.275/1.375) and 0.195. s (R/. P = 0.3/0.6), respectively. Conclusion: Because the TR of a CT scanner is not accurately depicted in the specifications of the individual scanner, appropriate acquisition conditions should be determined based on the actual TR measurement. © 2016 Associazione Italiana di Fisica Medica.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Associazione Italiana di Fisica Medica / Elsevier"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ejmp.2016.02.015","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.elsevier.com/locate/issn/11201797","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © Elsevier (CC-BY NC ND)"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11064306","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1120-1797","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hara, Takanori"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Urikura, Atsushi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ichikawa, Katsuhiro"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Hoshino, Takashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishimaru, Eiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Niwa, Shinji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-ICHIKAWA-K-625.pdf","filesize":[{"value":"628.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-ICHIKAWA-K-625.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/14226/files/ME-PR-ICHIKAWA-K-625.pdf"},"version_id":"b7a27274-0d81-4186-b2ce-2256c0e4de75"}]},"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":"Temporal resolution measurement of 128-slice dual source and 320-row area detector computed tomography scanners in helical acquisition mode using the impulse method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temporal resolution measurement of 128-slice dual source and 320-row area detector computed tomography scanners in helical acquisition mode using the impulse method"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"14226","relation_version_is_last":true,"title":["Temporal resolution measurement of 128-slice dual source and 320-row area detector computed tomography scanners in helical acquisition mode using the impulse method"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T00:50:52.402891+00:00"}
