3D fan-beam model implimentation in a Hybrid Digital-Breast-Tomosynthesis Microwave Radar Imaging breast cancer detection algorithm

A 3D Fan-Beam model is presented to reduce computation time for Hybrid Digital-Breast-Tomosynthesis Microwave Radar Imaging breast cancer detection and imaging algorithms. The physical justifications for this model are described as well as the class of problems for which it is appropriate. A numerical experiment is presented using the new model in a breast cancer imaging algorithm to successfully reconstruct the location of a cancerous lesion in three dimensions.
