Abstract. An electrical impedance tomography (EIT) system images internal
conductivity from surface electrical stimulation and measurement. Such systems
necessarily comprise multiple design choices from cables and hardware design to
calibration and image reconstruction. In order to compare between EIT systems and
to study the consequences of changes in system performance, this paper describes a
systematic approach to evaluate the performance of the EIT systems. The system
to be tested is connected to a saline phantom in which calibrated contrasting test
objects are systematically positioned using a position controller. A set of evaluation
