Electrical impedance tomography system introduced

Saelig Company, Inc. now offers the Sciospec ISX-3 Electrical Impedance Tomography System. EIT is a non-invasive medical and industrial imaging modality in which the electrical impedance of a part of a body or object is measured by surface electrode measurements and converted in software to display a tomographic, sliced image of that part to reveal anomalies. Electrical conductivity varies in biological tissues and other non-uniform objects. Small alternating currents applied to some, or all of the electrodes allow potentials to be recorded from the other electrodes in varying electrode configurations. A two-dimensional tomogram can then be constructed using appropriate imaging algorithms. These measurements at multiple frequencies also allow for Electrical Impedance Spectroscopy.

Designed for researchers, the system allows for fully simultaneous acquisition of impedance or potential signals on up to 256 electrodes. This opens up new possibilities for monitoring highly dynamic and spatially distributed electro-physiological phenomena and enables in-depth insights into complex cell and non-uniformity interactions using customised application-specific sensor adapters.

The EIT systems (EIT16/32/64/128+) are specifically designed for electrical impedance tomography measurements. They offer true parallel measurements and tightly synchronised switching for fast frame rates.

The system is ideal for researchers and industrial users in applications where Electrical Impedance Spectroscopy and Electrical Impedance Tomography are useful.
