Numerical Simulations of MREIT Conductivity Imaging for Brain Tumor Detection
Figure 2
Axial slice of single anomaly model showing (a) voltage , (b) current density magnitude , and (c) magnetic flux density values without anomaly present; and changes caused in the same slice with the anomaly having a 200% conductivity contrast from the brain background as (d) , (e) , and (f) Δ distributions. Results are shown for LR current flow only. The injected current had 3 mA amplitude and a total current pulse width of 30 ms.
