WebJan 26, 2024 · The distorted Born iterative method reduces a nonlinear inverse scattering problem to a sequence of (ill-posed) linear inverse scattering problems that can be solved using a regularized least-squares formulation. This method was originally applied to two-dimensional electromagnetic problems but has been implemented to solve acoustic and ... WebAbstract: The inversion of induction tool measurements using the distorted Born iterative method (DBIM) and the conjugate gradient-fast Fourier-Hankel transform (CG-FFHT) is described. The inverse problem is formulated in terms of an integral equation of scattering where the unknown to be sought is the conductivity in the rock formation, …

WebN2 - One of the most powerful approach in ultrasound tomography (UT) is making use of distorted Born iterative (DBI) method to reconstruct high quality image in order to help locate and identify tumors more precisely. Due to its iterative nature, it begins with Born approximation as the initial guess. firefly optical transceiver
A New Inversion Method Based on Distorted Born …
WebJun 13, 2024 · Distorted born iterative method. In the previous sections we discussed the forward and the inverse model. Since the scattering function and the total field are unknown, we need an iterative algorithm to estimate them. The DBI solves the problem by using Born approximation to estimate the two parameters and solve for the inverse and forward ... Webgradient method [13], Born iterative method [14], subspace optimization method [15], and the distorted Born iterative method (DBIM) [16, 17] are the most popular deterministic algo-rithms. Among them, DBIM is awidely used regularized iterative algorithm because of its abil-ity to reconstruct high-resolution images with a faster rate of convergence. WebDec 4, 2024 · The distorted Born iterative method (DBIM) is used to solve two-dimensional inverse scattering problems, thereby providing another general method to solve the two-dimensional imaging problem when ... firefly optimization algorithm python code
