| Summary: | The electrical impedance tomography (EIT) is a non-invasive, no ionization radiation, low power consumption and low-cost imaging technique. The design and development of the EIT system by using 16 by 3 electrodes has been proposed to be evaluated on the cylindrical phantom. The design consisted of hardware and software parts. The development of the hardware part includes the specification of the power supply, direct digital synthesis (DDS), instrumentation amplifier (IA), multiplexer, RMS to DC converter, 24-bit analog to digital converter (ADC), control unit and phantom design. The data was collected using the neighboring technique. The reconstruction of the image was then performed using pyEIT based on the collected data. The result from this system could display the image inside the phantom location and shape. |
