With a series of processing steps in the four-dimensional medical images, the feature points of ventricular inner and outer wall are obtained. A B-spline surface is then used to build the dynamic deformation model of the myocardial walls. With such a surface model, a hexahedron control mesh can be constructed by sweeping the cloud data, and the ventricular solid model is built by fitting the trivariate B-spline parameters. Based on these models, a method of isogeometric analysis can be applied to calculate the stress and strain continuously distributed in the ventricle. The model is represented smoothly in the cylindrical coordinate system and is easy to measure myocardium dynamics for finding abnormal motion. Experiments are carried out for comparing the stress and strain distribution. It is found that the solid model can determine ventricular dynamics which can well reflect the deformation distribution in the heart and imply early clues of cardiac diseases.<\/jats:p>","DOI":"10.1155\/2012\/634534","type":"journal-article","created":{"date-parts":[[2012,2,12]],"date-time":"2012-02-12T16:01:39Z","timestamp":1329062499000},"page":"1-6","source":"Crossref","is-referenced-by-count":1,"title":["Solid Dynamic Models for Analysis of Stress and Strain in Human Hearts"],"prefix":"10.1155","volume":"2012","author":[{"given":"Qiu","family":"Guan","sequence":"first","affiliation":[{"name":"College of Computer Science and Technology, Zhejiang University of Technology, Hangzhou 310023, China"},{"name":"College of Information Engineering, Zhejiang University of Technology, Hangzhou 310023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miaomiao","family":"Lu","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Zhejiang University of Technology, Hangzhou 310023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Zhejiang University of Technology, Hangzhou 310023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cao","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Zhejiang University of Technology, Hangzhou 310023, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.3390\/s101211428"},{"issue":"5","key":"2","first-page":"404","volume":"21","year":"2002","journal-title":"Chinese Journal of Biomedical Engineering"},{"issue":"8","key":"3","first-page":"1028","volume":"19","year":"2007","journal-title":"Journal of Computer-Aided Design and Computer Graphics"},{"year":"2009","key":"4"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TNS.2009.2016196"},{"key":"8","first-page":"765","volume":"1","year":"2008","journal-title":"BioMedical Engineering and Information"},{"issue":"12","key":"9","first-page":"2221","volume":"22","year":"2010","journal-title":"Journal of Computer-Aided Design and Computer Graphics"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1002\/nme.2864"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2010.2070062"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/416963"},{"issue":"1","key":"14","first-page":"71","volume":"39","year":"2007","journal-title":"Journal of Nanjing University of Aeronautics and Astronautics"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1049\/el:20070576"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/634534.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/634534.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2012\/634534.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,2]],"date-time":"2016-08-02T18:52:21Z","timestamp":1470163941000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2012\/634534\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":12,"alternative-id":["634534","634534"],"URL":"https:\/\/doi.org\/10.1155\/2012\/634534","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"type":"print","value":"1748-670X"},{"type":"electronic","value":"1748-6718"}],"subject":[],"published":{"date-parts":[[2012]]}}}
