The Research of ECT system based on rotational electrodes array

Owing to the number limit of electrodes, the resolution is low in ECT system currently. But increasing the number of electrode plates will lead to decrease the area of electrodes and lower the SNR. In this paper, with the method of electrodes subdividing and rotational combination, the ECT measurement system of rotational capacitor electrodes array is built, which can increase projection data and improve reconstruction image resolution without decreasing the area of electrodes.
