Saelig Introduces Sciospec ISX-3 Electrical Impedance Tomography System


The ISX-3 EIT system allows for simultaneous acquisition of impedance or potential signals on up to 256 electrodes over a broad frequency range of up to 1 MHz

Saelig Company, Inc. has introduced the Sciospec ISX-3 Electrical Impedance Tomography System. 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.

Sciospec ImageDesigned 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 customized 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 synchronized switching for fast frame rates.

  • 16 to 256 channels in standard configurations
  • simultaneous sampling of all channels
  • Measurements at 100 mHz to 10 MHz, mOhm…Tohm
  • Configurable injection patterns
  • Broad frequency range (e.g. 100 Hz to 1 MHz)
  • Spectral measurements with sweeps with up to 128 frequencies
  • Current excitation from 100 nA … 10 mA
  • Frame rates up to 100 fps
  • Imaging algorithm software provided
  • Advanced features like ECG synchronization, synchronous complex stimulation, etc.
