In electrical impedance imaging, several proposed reconstruction algorithms have employed the concept of a sensitivity matrix, which can be used to relate the magnitude of a boundary voltage change of a 2D object to the change in conductivity inside the object that has given rise to it. The search for an appropriate inversion of the sensitivity matrix is the key to these algorithms. In this work, a method called the direct sensitivity matrix (DSM) approach for fast image reconstruction is proposed. Both theoretical and experimental results showing the efficiency of this proposed method are also presented.
在电阻抗成像中，几种已提出的重建算法采用了灵敏度矩阵的概念，该矩阵可用于将二维物体边界电压变化的幅度与引起该变化的物体内部电导率变化联系起来。寻找灵敏度矩阵的合适求逆方法是这些算法的关键。在这项工作中，提出了一种称为直接灵敏度矩阵（DSM）方法的快速图像重建方法。还给出了表明该方法有效性的理论和实验结果。
