A MATLAB-Based Boundary Data Simulator for Studying the Resistivity Reconstruction Using Neighbouring Current Pattern

Figure 6

Image reconstruction of a simulated domain with a circular inhomogeneity (𝑅_𝑝=75mm, 𝑟_𝑖=30mm, 𝜎_𝑖=0.005S/m, and 𝜎_𝑏=0.21S/m) at different positions (𝑟,𝜃): (a) simulated domain with inhomogeneity at 𝑟=0mm and 𝜃=0^∘, (b) reconstructed image of the domain shown in Figures (a) and (c) simulated domain with inhomogeneity at 𝑟=37.5mm and 𝜃=0^∘, and (d) reconstructed image of the domain shown in Figure (c).
