*"Current Density Impedance Imaging of an Anisotropic Conductivity in a 
Known Conformal Class"*

**

/Abstract: /

/We present recent results on determining anisotropic conductivities 
from current density and diffusion tensor measurements which can be 
obtained using Magnetic Resonance Imagers. The mathematical problem is 
to recover an anisotropic conductivity in a known conformal class from 
knowledge of one current. We show that the corresponding electric 
potential is the unique solution of a constrained minimization problem 
with respect to a weighted total variation functional defined in terms 
of the physical data. Further, we show that the associated equipotential 
surfaces are area minimizing with respect to a Riemannian metric 
obtained from the data. This is joint work with Robert Jerrard, Nicholas 
Hoell and Amir Moradifam. Experimental results are joint work with 
Weijing Ma, Nahla Elsaid, Michael Joy and Tim DeMonte./
