摘要：

A preliminary assessment for the development of a two-dimensional amplitude-only tomography approach is described in this work. An iterative inversion strategy is adopted, which is based on the contrast source scheme, but avoiding any intermediate phase retrieval stage. The presented method does not consider a priori information on the nature of the scatterer, while all the measured data are exploited within the starting guess. Some validation reconstructions are proposed in the field of breast imaging, by considering a simulated breast model with a malignant portion as test case. The proposed phaseless tomography scheme reveals the potential extension to biomedical applications, supporting the current cutting-edge bio-imaging techniques.
