An electrical impedance tomography system for gynecological application GIT with a tiny electrode array.

The paper describes the development of an electrical impedance tomography (EIT) system for gynecologic research. The GIT (gynecological impedance tomography) system has 48 electrodes and is embedded on a small space (30 mm diameter and 20 mm height) inside of the vaginal probe. The system provides real-time (one shot per second) 3D visualization of the spatial distribution of the static electrical properties of the cervix tissue.

Experimental demonstration of electric field tomography.

Electric field tomography (EFT) has recently been introduced in theory. It is a new kind of quasistatic tomography suitable for contactless imaging of biological tissues. Single-channel measurements have already proven the theory.

Phase measurement for electric field tomography.

The basic principles of electric field tomography (EFT) are briefly explained. EFT system numerical simulation results are given. The comparison of images reconstructed by systems with planar and round electrode arrays is presented.

Electric field tomography: setup for single-channel measurements.

Results of experiments on electric field tomography, which were carried out to test the theoretical model suggested previously, are described in this paper. The theoretical foundation of the electric field tomography and substantiation of the possibility of its biomedical application are briefly presented. An experimental setup and test samples used for measurements are described.
