Time-difference phantom experiment

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

Time-difference EIT(tdEIT) is to recover the time change of conductivity distribution using the time change of voltage data.

User made java GUI can control Sciospec EIT device to perform tdEIT experiments. The following figure is the picture of the device control panel in the GUI made by EIT group in Yonsei University. To perform tdEIT, we put insulating glass in the circular saline tank. The reference voltage data is measured in the absence of the glass. The author made reconstruction algorithm is used to locate the position of the glass.
