Practical Design and Implement of Electrical Impedance Scanning Prototype for Clinical Breast Detection

摘要

Practical research is very important for breast electrical impedance scanning (EIS) system industrialization. To satisfy the requirement of clinical application, some practical researches on EIS system were conducted, which included the real-time detection mode, multi-frequency parameter analysis and hardware system design. Based on a standard resister network, the performance of EIS hardware system was evaluated and some satisfying results were got. Further, an initial clinical experiment was performed in the new EIS system. The results showed that the detection-time can be shorten about 4 minutes, DFR of the measuring data was decreased from (-14.1%～16.6%) to (-12.8%～15.0%), and the detection accuracy was improved about 8%. These demonstrated that the practical researches can effectively improve the performance of the EIS system.
