[A simulation study of electrical impedance scan-imaging based on a phantom].

OBJECTIVE To testify the feasibility of electrical impedance scanning (EIS) imaging and to classify the factors influencing EIS imaging at the early stage of electrical impedance scanning breast imaging study. METHOD Based on the EIS experiment workplace, a phantom to simulate the distribution of breast tissue was designed. Using NaCl solution and agar block with different conductance, three kinds of electric fields disturbances were simulated. RESULT Different electric fields disturbance induced by different conductance distributions bring different imaging effects. CONCLUSION The imaging based on the theory of EIS is feasible. Initiative factors influencing EIS imaging are confirmed.
