Abstract

Diffraction tomography theory describes both the forward and inverse problems in media where electromagnetic radiation propagation must be modeled in terms of its wave nature. In general, this theory assumes media in which the radiation is not attenuated. We have recently extended this theory to include the attenuating media case. Here, we apply this newly-developed theory to analyze a tumor localization algorithm which permits three-dimensional tumor localization from a single two-dimensional measurement. We demonstrate that this algorithm can be viewed as a backpropagation algorithm. With this insight, show how tumor localization occurs.
