A Data Focusing method for Microwave Imaging of Extended Targets
This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...
متن کاملInverse scattering problem for the Impulsive Schrodinger equation with a polynomial spectral dependence in the potential
In the present work, under some di¤erentiability conditions on the potential functions , we rst reduce the inverse scattering problem (ISP) for the polynomial pencil of the Scroedinger equation to the corresponding ISP for the generalized matrix Scrödinger equation . Then ISP will be solved in analogy of the Marchenko method. We aim to establish an e¤ective algorithm for uniquely reconstructin...
متن کاملStudy of the Compton scattering effect of soft tissue in PET imaging by Monte Carlo method
Introduction:In PET imaging, one or both of two annihilation photons may change the direction before reaching the detector due to Compton scattering interaction in body. .Methods:This article, a Monte Carlo simulation study, examined the effect of soft tissue on this error.In this work, the PET BiographTM 6 scanner, a simple geometry of soft tissue -including a sphere of soft tissue in center ...
متن کاملNonlinear diffraction tomography: The use of inverse scattering for imaging
Our recent inverse scattering work has been to derive inverse scattering theory and algorithms that can be used to process practical experimental data. The theory makes use of computation of the forward scattering solution. Therefore, an eecient forward solver is instrumental to the rapid solution of the inverse scattering problem. The advantage of the more sophisticated theory over a linear th...
متن کاملAn Evaluation of Computational Imaging Techniques for Heterogeneous Inverse Scattering
Inferring internal scattering parameters for general, heterogeneous materials, remains a challenging inverse problem. Its difficulty arises from the complex way in which scattering materials interact with light, as well as the very high dimensionality of the material space implied by heterogeneity. The recent emergence of diverse computational imaging techniques, together with the widespread av...
متن کاملCompressive inverse scattering using ultrashort pulses
Inverse scattering refers the retrieval of the unknown constitutive parameters from measured scattered wave fields, and has many applications such as ultrasound imaging, optics, T-ray imaging, radar, and etc. Two distinct imaging strategies have been commonly used: narrow band inverse scattering approaches using a large number of transmitters and receivers, or wideband imaging approaches with s...
