Abstract :
We study the effect of noise on microwave breast imaging by numerical simulations. A high contrast breast model is considered and the image reconstructions are carried out in time domain using a nonlinear inversion algorithm. A relative reconstruction error is defined in order to quantitatively evaluate the image distortion due to noise. The relative reconstruction errors of noisy reconstructions are obtained when different levels of amplitude and phase errors are taken into account.
