This paper will discuss the inclusion of anatomical constraints and an
isotropy in static Electrical Impedance Tomography (EIT) using a two-s
tep approach to EIT. In the first step, the boundaries between regions
of different conductivities are anatomically constrained using Magnet
ic Resonance Imaging (MRT) data, In the second step, the conductivity
values in different regions are determined, Anisotropic conductivity r
egions are included to allow better modeling of the muscle regions (e.
g., skeletal muscle) which exhibit a greater conductivity in the direc
tion parallel to the muscle fiber, This two-step approach is used to r
econstruct the conductivity profile of a canine torso, illustrating it
s potential application in extracting conductivity values for bioelect
ric modeling.
