Background:

  • Multifrequency electrical impedance tomography (EIT) requires precise calibration.
  • Accurate phantoms are essential for testing and comparing EIT data collection systems.

Purpose of the Study:

  • To design and construct a phantom for evaluating multifrequency EIT systems.
  • To simulate complex tissue impedance using the Cole equation.

Main Methods:

  • A cylindrical phantom with 16 drive and 16 receive electrodes was created.
  • Resistors and capacitors simulated tissue impedance obeying the Cole equation (Z*).
  • Four distinct spectroscopic parameter sets were implemented for testing.

Main Results:
