Figure 6: Reconstructed conductivity images of 5, 7.5, 10, and 15 mm diameter tumor-like anomalies having complex structures. The conductivity value of the angiogenic tumor region was two times higher than normal tissues and that of the necrotic region was 0.01 S/m. Conductivity images were obtained at different numbers of averages   (top to bottom) and current amplitudes (left to right). Noise was added to the simulated voxel data, based on experimental measurements of noise in 3 T MR system.
