Cubic hermite bezier spline based reconstruction of implanted aortic valve stents from CT images


Gessat, M; Altwegg, L; Frauenfelder, T; Plass, A; Falk, V (2011). Cubic hermite bezier spline based reconstruction of implanted aortic valve stents from CT images. IEEE Engineering in Medicine and Biology Society. Conference Proceedings, 2011:2667-2670.

Abstract

Mechanical forces and strain induced by tran-scatheter aortic valve implantation are usually named as origins for postoperative left ventricular arrhythmia associated with the technique. No quantitative data has been published so far to substantiate this common belief. As a first step towards quantitative analysis of the biomechanic situation at the aortic root after transapical aortic valve implantation, we present a spline-based method for reconstruction of the implanted stent from CT images and for locally measuring the deformation of the stent.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
