In this paper, a new capacitive tomography (ECT) algorithm based on the sensitive field transform is proposed. The formula of sensitive field transform and the new formula of determining threshold are given. The results of computer simulation show that the improved algorithm has obvious improvement on the imaging results of various phase concentration distributions, which proves that the algorithm is more advanced than before.
