The present text introduces the concept of data collecting (voltages and currents) from a phantom connected to electrical impedance tomography. The concept involves a method for signal multiplexing from up to 256 electrodes and the current source for such probes. Considering the high number of electrodes and the estimated extended distances between the probes and the measuring card, the method recommends using probes to convert the measured voltage to a current loop, making them suitable for measuring small voltage levels in the millivolt range.
