摘要
在心内膜定位与标测系统中,三维心腔模型的构建起着重要的作用。本文介绍了一种利用凸包算法,从心腔内导管电极的位置信息中提取心腔的表面数据,以此构建心腔舒张期的三维模型,并成功地用于基于VTK的心腔三维重建。
In this paper, a method based on the convex hull algorithm is presented for extracting modelling data from the locations of catheter electrodes within a cardiac chamber, so as to create a 3-D model of the heart chamber during diastole and to obtain a good result in the 3-D reconstruction of the chamber based on VTK.
