Global Maxwell Tomography (GMT) is a recently introduced technique that estimates tissue
electrical properties from magnetic resonance measurements by solving an inverse
scattering problem. In this work, we propose a new implementation of GMT that uses a
Projected Newton method to minimize the cost function, instead of the quasi-Newton method
employed by the original GMT. We demonstrated the new approach with two numerical
experiments, using a four--compartment phantom and a realistic head model. Compared to …
