Electrical Impedance Tomography (EIT) isa non-invasive medical imaging technique which estimates
the electrical impedance distribution within tissue. The basic principle of EIT isa mapping of the
immittance distribution (tomography) usingthe measurement of some passive electrical properties of
tissue named bioimpedance.The study aimed to assess the performance of the EIT system in
detectingan anomaly in thorax imaging with varying different frequencies, by analysis of sensitivity
distribution. Sensitivity distribution was visualized using COMSOL Multiphysics simulation in a
human thorax represented as an elliptic cylinder phantom consisting ofan inhomogeneous medium
within and without an anomaly represented by a sphere. Current density distribution was collected for
sensitivity analysis using the neighboring method with current injection at 1 mA for each pair of
electrodes with frequencies 70, 100, and 130 kHz. Results indicate that the modeled two dimensional
EIT detected changes in the inhomogeneous media with and without anomaly inside the modeled
thorax phantom very well
