Non-linear image reconstruction methods are desirable for applications in electrical impedance tomography (EIT) such as brain or breast imaging where the assumptions of linearity are violated. We present a novel non-linear Newton-Krylov method for solving large-scale EIT inverse problems, which has the potential advantages of improved robustness and computational efficiency over previous method...

We introduce fractal Newton methods for solving f(x)=0 that generalize and improve the classical method. compare theoretical efficacy of illustrate theory with examples.
