A new symmetric semi-parallel Electrical Impedance Tomography system has been developed and calibrated for physiological process monitoring. This article explains and demonstrates the advantages of the symmetric structure for bandwidth expansion. The wide frequency range, 1 kHz to 1 MHz, provides flexibility for different application purposes. The system performance tests show that, its Signal-to-Noise...
Electrical Impedance Tomography (EIT) is a kind of functional imaging technology which has great potential for tumor diagnosis, and physiological process monitoring. This article introduces a prototype design of a semi-parallel EIT data acquisition system with the purpose of ease of hardware upgrades and scalability. The system consists of one control module and an expandable number of independent...
