An Indirect Measurement Method for Electrical Impedance Scanning

When the phenomena that conductance of breast cancerous tissue is higher than which of normal tissue around was found, researches using impedance imaging for breast cancer detection come forth. Electrical impedance scanning (EIS) acquires more applications in clinic for its simple hardware design and image reconstruction. However, EIS is more easily influenced by noises because of its geometrical settings. After an analysis of EIS principle, a novel measurement method-Indirect Measurement Method (IMM) is brought forward. Simulation experiments demonstrate that IMM could be used in image noises suppression with a reference image and improve performance of EIS effectively.
