In the research on the brain functional changes observation with the EIT method, because the skull has a higher resistance, much of the applied current pass the scalp between electrodes instead of entering the brain. The signal resulted from the changes in the brain is substantially attenuated this decrease the sensitivity to the central resistance change. In this paper, measurements of human skull impedance were made quantitatively by the two-electrode method in the frequency range from 0.1 Hz to 1 MHz with a Solartron 1255B frequency response analyzer. The impedance-frequency response curves of human skull were obtained, and the impedance frequency response curves of human skull with different anatomic structures are compared as well. By analyzing the curves, it is found that: (1) The characteristic frequency of human skull should be in the frequency range 1 KHz∼100 KHz. (2) The capillary vessel in the skull is a key factor affecting skull impedance.

Tang M, Dong X, Qin M, et al., 1998, [Implementing a relatively rigorous algorithm of dynamic EIT problem on the modified FEM model]., Sheng Wu Yi Xue Gong Cheng Xue Za Zhi, Vol: 15, Pages: 158-162, ISSN: 1001-5515
We deduced a relatively rigorous algorithm of dynamic EIT problem-general inverse algorithm, and implemented it on the computer FEM model. Images which can show the changing of the resistivity(i.e. dynamic resistivity images) were gained. Also we modified the ordinary FEM model according to the characteristic of the EIT problem and implemented the general inverse algorithm on the modified model. The ill-posed condition of the forward matrix based on the modified model was fairly improved. It can be seen from the results that the general inverse algorithm with modified FEM model is an algorithm better than the back-projection algorithm in terms of object locating, image definition, and the ability of dealing with complex object and noise.
