三维可视化显示心外膜电生理参数的方法

A Method to Display 3D Visualization of Cardiac Electrophysiologic Parameters

利用一种三维可视化显示心外膜电生理参数的方法,巧妙地将空间三维曲面变换到平面上并用Delaunay三角剖分进行图像处理,用重心坐标系进行插值,从而重建出一个较光滑的心外膜模型及其上的电生理参数分布。此方法提供了心外膜电生理参数直观且快速的显示方法。

This paper proposes a method to display 3D visualization of cardiac electrophysiologic parameters. In this method, a 3D surface is transformed with Delaunay triangulation to a plane. The values are interpolated in the barycentric coordinate system. Then a smooth epicardial model is reconstructed with a distribution of electrophysiological parameters on its surface. This method provides an intuitive and fast way to display epicardial electrophysiologic parameters.
