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 N  (top to bottom) and current amplitudes (left to right). Noise was added to the simulated B _z voxel data, based on experimental measurements of B _z noise in 3 T MR system.
