摘要: 本文提出了电阻抗成象的图象重建算法中一种新的电导率分布函数逼近方法连续插值函数逼近法.它充分利用有限元方法计算上的特点,在计算量不增加甚至有所减少的情况下,获得了比传统的分片常数逼近法更好的图象重建效果.Abstract: A new approximation method to distribution function of conductivity for electrical impedance tomography image reconstruction algorithm is proposed in this paper. This method is called continuous interpolation function method. Compared with the conventional piecewise constant method, the image reconstructed by this method is much better, while the amount of computation is not increased or even decreased because the good property of finite element method has been used sufficently.
