Multi-Frequency Electrical Impedance Tomography: Complex Sensitivity Matrix Performability Evaluation for Image Reconstruction

Electrical Impedance Tomography (EIT) is a noninvasive medical technique for imaging the conductivity distribution of body section. In multi-frequency EIT many factors affect the image reconstruction results. Among them are number of electrodes, the values of the complex of the sensitivity matrix.In this paper an appropriate complex sensitivity matrix is shown, performability of the matrix is evaluated and image reconstruct is given.

I. INTRODUCTION:

The first Biomedical using of electrical impedance tomography was in the late of 1970s [1], where it used to image the lung. safe current is applied with electrodes on surface of the body, then measure the resulted voltage and Computes conductivity then reconstruct image depending on some protocols.
