This paper describes a method for creating a patient specific replica of the whole aorta. Methods: Computed tomography angiography (CTA) DICOM-data was converted to a three-dimensional computer aided design-model (CAD) of the inner wall of the aorta representing the lumen where the calcified plaque contribution was removed in a multi-step editing-manoeuvre. The edited CAD-model was used for creating a physical plaster model of the true lumen in a 3D-printer. Elastic and transparent silicon was applied onto the plaster model, which was then removed leaving a silicon replica of the aorta. Results: The median (interquartile range) difference between diameters obtained from CTA- and RP plaster-model at 19 predefined locations was 0.5 mm (1 mm) which corresponds to a relative median difference of 4.6% (7.0%). The average wall thickness of the silicone model was 3.5 mm. The elasticity property and performance during intervention was good with an acceptable transparency. Conclusions: The integration of RP-techniques with CAD based reconstruction of 3D-medical imaging data provides the needed tools for making a truly patient specific replica of the whole aorta with high accuracy. Plaque removal postprocessing is necessary to obtain a true inner wall configuration. <\/jats:p>","DOI":"10.1024\/0301-1526\/a000148","type":"journal-article","created":{"date-parts":[[2013,2,2]],"date-time":"2013-02-02T02:21:08Z","timestamp":1359771668000},"page":"453-459","source":"Crossref","is-referenced-by-count":37,"title":["Patient specific biomodel of the whole aorta - the importance of calcified plaque removal"],"prefix":"10.1024","volume":"40","author":[{"family":"H\u00e5kansson","sequence":"first","affiliation":[{"name":"Divisions of Industrial Design, Lule\u00e5 University of Technology, Lule\u00e5, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Rantatalo","sequence":"additional","affiliation":[{"name":"Division of Operation and Maintenance Engineering, Lule\u00e5 University of Technology, Lule\u00e5, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Hansen","sequence":"additional","affiliation":[{"name":"Departments of Radiology, Uppsala University Hospital, Uppsala, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Wanhainen","sequence":"additional","affiliation":[{"name":"Department of Surgical Sciences, Section of Vascular Surgery, Uppsala University Hospital, Uppsala, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"101","container-title":["Vasa"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526\/a000148","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T11:52:14Z","timestamp":1652010734000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526\/a000148"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,11,1]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2011,11,1]]}},"alternative-id":["10.1024\/0301-1526\/a000148"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526\/a000148","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"value":"0301-1526","type":"print"},{"value":"1664-2872","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,11,1]]}}}
