Abstract
Abstract: High-resolution image reconstruction of interest region is one of the research hotspots of electrical capacitance tomography (ECT) technology. The ECT model with uniform electrode distribution only has a high sensitivity coefficient at the boundary position of the reconstructed field and is not suitable for imaging regions of interest. In order to improve the sensitivity distribution in the region of interest and improve image resolution, a high-resolution image reconstruction method of ECT region of interest based on finite element simulation is proposed, and the electrode distribution is optimized according to the conformal transformation theory. Simulation experiments are conducted, and the sensitivity matrices of uniform electrodes and optimized electrode distribution are substituted into the Tikhonov, Landweber, and ART algorithms. Reconstruction results show that the above method can effectively improve image reconstruction accuracy of interest region.
