Figure 1

Cylinder shaped metallic electrodes (Electrode) are mounted on a thin plastic catheter, which was intraluminal introduced (Wall). Each neighboring electrode pair is connected to an impedance voltage transducer outside the body (Zn = measured impedance of an electric field between two electrodes at the moment, which is the ratio between the applied voltage (U) and the resulting current (I). The instantaneous output voltage of each transducer represents the average electrical impedance of the volume conductor around the catheter.
