Summary:An electrical impedance scanning (EIS) system was studied to meet the requirement of clinical breast screening. A quick examination, easy operation, safe electrical isolation and obvious diagnosis results are four main factors to a screening system. Basing on these considerations, a multi-frequency signal sampling system controlled by ARM chip was setup and the measuring data were transmitted to PC by an ethernet interface. For the measuring probe, three types of electrodes array were designed to adapt the different sizes of breast. Additionally, an imaging post-process algorithm was developed to assist the radiologist to have an obvious diagnosis results. Based on a saline-tank phantom and some satisfying results were got. The system has a character of high precision, real-time imaging and obvious results and can be used in the clinical study of EIS breast screening.
