心电仿真中人体躯干计算机图形的建立及离散化处理

Establishm entand Discretization of Human Torso Computer Images for ECGSimulation

人体躯干计算机图形的建立及其离散化是心电仿真研究的一个重要方面。本文介绍一种快速有效的方案，通过曲线拟合的方法，并引入“虚点”的概念，比较精确地建立了人体躯干离散化图形。另外这种方法对于解决电磁场数值求解过程中的场域剖分问题也具有一定的实用价值。

The establishm ent and discretization of hum an torso com puter im age is an im portantas pect in studying of ECG sim ulation. A rapid and effective m ethod is presented in this paper, w hich es tablishes and discretes im age ofhum an torso exactly by curve fitting and by introducing concept of “ni hility point”. It also has som e value for solving problem of discreting field region in num ericalcalcula tion of electrom agnetic field.
