Özet

In this study, development of a microcontroller controlled multifrequency electrical impedance tomography system is aimed. In this system, current injection and voltage measurements are both performed by the surface electrodes, which are microcontroller controlled. Data acquisition system process the measured signal using continuous time quadrature demodulator. After that, it converts analog information to digital and transfers it to the PC.
