Step 1: |
Defining the filtering method to eliminate the muscle’s conductivity distribution and unexpected noise background |
Obtain: Equation (4) |
Step 2: |
Using voltage data t = 0 as an initial conductivity distribution, selecting the mesh of SAT on the forward problem mesh condition, calculating the fat weighted threshold value
\overline {{{\hat \sigma}_{fat}}} + std\left({{{\hat \sigma}_{fat}}} \right)
|
Obtain: the fat weighted threshold value
\overline {{{\hat \sigma}_{fat}}} + std{\left({{{\hat \sigma}_{fat}}} \right)_s}
|
Step 3: |
Applying the filter on equation (4) to experimental data |
Obtain:σabs and σ |
Step 4: |
Using voltage data t = 30, 60, and 90 mins to evaluate the varying water content to obtain the conductivity distribution, applying equation (5) |
Obtain: σdiff |
