Abstract :
Using the full Maxwell Equations model (full model) as a forward model for Electrical Impedance Tomography (EIT) in the mammography geometry instead of an approximation may be more desirable if the approximations introduce large errors. This paper examines the full model, and the relative errors between the full model and the approximations. We show that at high frequencies there are large relative errors between the full model and the approximations, and thus it may be more appropriate to use the full Maxwell equations as a forward model for EIT in the mammography geometry.
