Overview

This approach improves induced electric field accuracy in anatomical models, suggesting better EMF exposure limits.

Key Points

  • The tensor-based SPFD method reduced RMSE by up to 65%, enhancing accuracy in estimating electric fields.
  • In realistic head models, numerical artifacts were suppressed by the new method, reducing peak electric field by up to 22%.
  • The computational efficiency was improved by a 25-fold speedup using a multigrid method, maintaining accuracy.
  • This method could refine EMF exposure limits, improving simulation reliability for medical uses.
