The system adopts AD5933 as the impedance sensor, realizes the data communication between AD5933 and S3C2440 processor by using I / 2C communication protocol, develops the QT user interface to display the measurement results, and realizes the collection and display of impedance parameters by operating the touch screen. Save and curve drawing function. The experimental results show that the image reconstruction quality is good, and the signal-to-noise ratio (SNR) of 65.6 dB, verifies the reliability and stability of the software and hardware design of the system. This research is helpful to promote the development of impedance measurement technology in digital medical and clinical applications.
