Simulation method of electrode structure design for intraoperative margin assessment of breast cancer focus

The intraoperative margin assessment of breast cancer based on impedance measurement technology could relieve the physical and psychological discomfort of patients. The optimization of electrode structure is important while designing the facility used in the assessment, which requires simulation of sensitivity distribution of the electrode. The simulation analysis method using ANSYS is studied in this paper. In the process of model building, it had been found and validated that the meshing mode influenced simulation results. In order to eliminate the influence, a new model building method is presented. The symmetry of the new approach had been certificated, which was used to reduce the simulation process.
