We investigated the effects of measurement uncertainty on the image reconstructions for different breast models. Three different contrast levels between the background tissue and tumor were chosen. It was shown that the reconstruction of lower contrast breast model was more sensitive to the measurement uncertainty. For a breast model with contrast as low as 1.1 : 1, an amplitude uncertainty of 0.2 dB or a phase uncertainty of 2 degrees would result in an unsuccessful reconstruction.
