An Interdisciplinary Workshop on Mathematical Methods in Biomedical Imaging and Intensity-Modulated Radiation Therapy (IMRT)

seminar: Time Reversal Based Direct Imaging Algorithms

speaker: Hongkai Zhao (Department of Mathematics, University of California, Irvine, USA)

abstract: I will introduce a few direct imaging algorithms which are based on a physical factorization of the scattered wave field. Singular value decomposition and a resolution based thresholding strategy is used to extract principlal components of the shape space. These principal components are used to match appropriately chosen illumination vectors in the imaging function. Our algorithm does not need any iterations nor forward solver. I will demonstrate our algorithms for both near field and far field data as well as well for different material properties.
