Abstract
Electrical Impedance Tomography is a soft-field technique able to generate images for several applications where a safe, non-intrusive and non-invasive approach is mandatory. This paper presents the study of a hardware implementation of an Electrical Impedance Tomography System, suitable for data acquisition and image reconstruction to microtomography applications, characterizing MicroEIT in the context of the different applications of existing tomography techniques, as well as highlights the temporal problem encountered in the approaches already developed. The concepts and elements of a MicroEIT system are shown in a proposal of hardware and software implementation using our measurement and excitation hardware, integrated to a CompactRIO and LabVIEW data acquisition system. Finally, it discusses the possibility of applications of this approach in cell culture studies.
