Abstract

This paper represents a reconstruction algorithm using a direct sensitivity matrix (DSM) approach for fast 3D image reconstruction in electrical impedance imaging. The boundary element method (BEM) is used in the construction of this matrix. The first images of a conductivity perturbation inside a sphere are reconstructed, using theoretical data.

摘要

本文提出了一种在电阻抗成像中使用直接灵敏度矩阵（DSM）方法进行快速三维图像重建的算法。在构建该矩阵时采用了边界元法（BEM）。利用理论数据重建了球体内部电导率扰动的首批图像。
