Saelig has introduced the new Sciospec ISX-3 Electrical Impedance Tomography System for medical and industrial applications.

EIT is a noninvasive 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 Sciospec ISX-3 EIT 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 allows in-depth insights into complex cell and non-uniformity interactions using customised application-specific sensor adapters. 

Sciospec’s EIT systems (EIT16/32/64/128+) are specifically designed for electrical impedance tomography measurements, offering true parallel measurements and tightly synchronised switching for fast frame rates.
