Journal ArticleDOI
Solution of inverse problems in elasticity imaging using the adjoint method
TL;DR: In this article, the problem of determining the shear modulus of a linear-elastic, incompressible medium given boundary data and one component of the displacement field in the entire domain is considered.
Journal ArticleDOI
Evaluation of the adjoint equation based algorithm for elasticity imaging
TL;DR: This paper examines the performance of a new adjoint equation based iterative method for evaluating the spatial distribution of the elastic modulus of tissue based on the knowledge of its displacement field under a deformation, and concludes that it is robust and accurate, and a good candidate for clinical application because of its computational speed and efficiency.
Journal ArticleDOI
Elastic modulus imaging: on the uniqueness and nonuniqueness of the elastography inverse problem in two dimensions
TL;DR: In this paper, the uniqueness of an N-field generalization of a 2D inverse problem associated with elastic modulus imaging is examined, where given?linearly independent displacement fields in an incompressible elastic material, determine the shear modulus.
Journal ArticleDOI
Solution of the nonlinear elasticity imaging inverse problem: the compressible case
TL;DR: A new strain energy density function with an exponential stress-strain behavior that yields a deviatoric stress tensor, thereby simplifying the interpretation of pressure when compared with other exponential functions is presented.
Journal ArticleDOI
Special transformations for pentamode acoustic cloaking
TL;DR: This paper defines desirable material properties and then deriving the appropriate transformations which guarantee the cloaking effect, resulting in acoustic cloaks with special properties such as constant density and minimal elastic anisotropy.
