Abstract：Objective To study a construction method of the fine breast electrical impedance simulation model. Methods Based
on mammary MRI enhanced scanning sequence, a fine breast three-dimensional geometric model was constructed using
Mimics, Geomagic and CAD software. After assigning electrical impedance parameters to this model, COMSOL software was
used to perform the finite element simulation analysis of the model. Results This method could construct a fine breast electrical
impedance simulation model containing distribution information of mammary electrical impedance. The simulation results, which
could show whether a high conductivity target was in a setting position of the model, were obtained by the electromagnetic finite
element simulation of the model and were consistent with the results of clinical impedance scanning detection. Conclusion The
simulation results provide a physical basis for clinical impedance scanning detection of breast cancer.
