Abstract :
We propose a variant of the Newton method that uses a fast solution of the direct problem and a dual mesh. Using this method, we are able to obtain good quality images of high contrast experimental phantoms. Our computational experiments show that a full scaled image of a two-dimensional mathematical model of a human torso can be obtained with this method.
