The probe current source is an essential component of equipment in electrical impedance tomography (EIT). This article discusses the development of a current source for an EIT - from a block diagram to a hardware implementation. A methodology for determining the output resistance of a current source is described, an experimental bench and the results of an experimental evaluation of the source output resistance - the most important parameter of current sources determining its characteristics - are presented.
