Lung ventilation imaging using EIT with Sciospec

Dr. Kyounghun Lee, Computional Science & Engineering, Yonsei University Seoul, South Korea

Pulmonary activity can be visualized with Sciospec 16-channel EIT device by using time-difference imaging technique.

Software can easily control Sciospec device to perform real-time image reconstruction.  The following images are of the software made by C#.

FER algorithm is used for the image reconstruction. See the paper ‘A fidelity-embedded regularization method for robust electrical impedance tomography’ for details.

Key Features of Sciospec EIT system

  • Fast Data acquisition - up to 100 frames per second

  • Wide Frequency range - from 100 Hz to 1 MHz

  • Provides user-defined Current injection and Voltage measure pattern
