Numerical Simulations of MREIT Conductivity Imaging for Brain Tumor Detection
Figure 7
Nomogram showing predicted noise levels compared to the estimated signal size at different pixel sizes using a fixed slice thickness of 4 mm and assuming a 10 mm anomaly diameter in both (a) white and (b) gray matter. Three different values of averaging NEX at of 30 ms and three different values of total current injection time at were used. The values of average Δ are compared for a simulated conductivity contrast of 200% and for an anomaly diameter of 10 mm.
