Numerical Simulations of MREIT Conductivity Imaging for Brain Tumor Detection

Figure 5

Reconstructed conductivity images of 5, 7.5, 10, and 15 mm diameter tumor-like anomalies having simple structures obtained using noisy data. 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.
