Abstract:An electrical impedance tomography imaging method incorporated with inhomogeneously-distributed skull resistivity was put forward in the paper, which made use of the anatomical information segmented from brain CT as well as the statistical parameter model of the diploe thickness and skull resistivity to establish a two dimensional brain finite element model containing inhomogeneously-distributed skull resistivity. A novel damped least squares incorporated with this model was used for simulation studies. According to the preliminary simulation experimental results, this imaging method showed its effectiveness in improved quality of reconstructed images and enhanced positioning accuracy of the imaging target.
