Reconstructing microwave near-field image based on the discrepancy of radial distribution of dielectric constant

Abstract

Based on the difference of dielectric properties between normal breast tissues and malignant tumors, microwave scatter-sounding method is used to detect the breast then get the projection reconstruction data. With the characteristics of radial distribution of the data, dielectric property of the detected space is reconstructed. In this paper, not only the microwave near-field imaging model is discussed in detail, but also the reconstruction result. The effectiveness of this method has been approved by the reconstruction result of some typical detected spaces. © 2009 Springer Berlin Heidelberg.
