Pseudo electrodes driven patterns for electrical impedance tomography

Electrical impedance tomography (EIT) is a powerful tool for mapping the electrical property of the estimated objects. The quality of impedance image is limited by the number of electrodes. In this paper we proposed a pseudo electrode driven patterns for electrical impedance tomography. By changing the measuring sites of the physical electrodes we can obtain the expanded pseudo electrodes. The modified adjacent method is also proposed to increase more independent measurement. The singular value plot of the adjacent method and pseudo electrode is provided to show the improvement of pseudo electrode scheme. The result shows that the pseudo provides the better image quality in EIT data collection. We hope the pseudo electrode scheme will bring some help in electrical impedance tomography.
