Journal ArticleDOI
Magnetic resonance electrical impedance tomography (MREIT): simulation study of J-substitution algorithm
TL;DR: A new image reconstruction algorithm called J-substitution algorithm produces cross-sectional static images of resistivity (or conductivity) distributions that are comparable to that of MRI.
Journal ArticleDOI
Reconstruction of conductivity and current density images using only one component of magnetic field measurements
TL;DR: This paper proposes a way to eliminate the requirement of subject rotation by careful mathematical analysis of the MRCDI problem, which needs to measure only one component of the induced magnetic flux density and reconstruct both cross-sectional conductivity and current density images without any subject rotation.
Journal ArticleDOI
Unique identifiability of elastic parameters from time-dependent interior displacement measurement
TL;DR: In this paper, the stiffness distribution of biological tissue from indirect measurements is determined using an inverse problem for the identification of coefficients in the second-order hyperbolic system that models the propagation of elastic waves.
Journal ArticleDOI
Interior elastodynamics inverse problems: shear wave speed reconstruction in transient elastography
TL;DR: In this article, a Lipschitz continuous arrival time satisfies the eikonal equation and two numerical algorithms, simulation results, and a reconstruction example using a phantom experiment accomplished by Mathias Fink's group (the Laboratoire Ondes et Acoustique, ESPCI, Universite Paris VII).
Journal Article
A numerical method for cauchy problem using singular value decomposition
June-Yub Lee,Jeong-Rock Yoon +1 more
TL;DR: In this paper, the singular values of the ill-posed Cauchy operator decay exponentially, which means that a small error is exponentially amplified in the solution of the problem, and the decaying rate is dependent on the geometry of the domain, which provides information on the choice of numerically meaningful modes.
