Abstract: 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.
Keywords: Electrical impedance tomography; current source; output resistance; experiment.
