摘要
Using an established finite-element simulation software suite developed in Tianjin, the authors analysed some factors which influenced the sensing field of an electrical resistance tomography (ERT) system. In order to improve the space evenness of the sensing field and 'focus'its effective measurement space, the authors described a guard electrode scheme, which improved both the quality of the reconstructed image and the delineation of conductive regions within the vessel.
