Elastography Method for Reconstruction of Nonlinear Breast Tissue Properties
Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. In this paper a nonlinear elastography method is introduced for reconstruction of complex breast tissue properties. The elastic parameters are estimated by optimally minimizing the difference between the computed forces and experimental measures. A nonlinear adjoint ...
متن کاملNonlinear Elasto-Mammography for Characterization of Breast Tissue Properties
Quantification of the mechanical behavior of normal and cancerous tissues has important implication in the diagnosis of breast tumor. The present work extends the authors' nonlinear elastography framework to incorporate the conventional X-ray mammography, where the projection of displacement information is acquired instead of full three-dimensional (3D) vector. The elastic parameters of normal ...
متن کاملConstrained Non-linear Elasticity Reconstruction Technique for Breast MRI Elastography
A. Samani, I. Sack, D. Plewes University of Toronto, Sunnybrook and Women's College Health Sciences Centre, Toronto, Ontario, Canada Synopsis To increase the displacement SNR in breast MR elastography, tissues are compressed significantly. As a result, breast tissues undergo large deformations. This leads to significant geometric and material nonlinearities. In this study, methods for treating ...
متن کاملA method for characterization of tissue elastic properties combining ultrasonic computed tomography with elastography.
OBJECTIVE The correlation between various diseases and the change in the local mechanical properties of soft tissues has been long known. Over the past 20 years, there have been increasing research efforts to characterize mechanical properties of biological tissues using ultrasonic elastography. However, most of these works were based on characterization of only 1 type of waves (longitudinal or...
متن کاملInvestigation of Shape Functions Role on the Mesh-free Method Application in Soft Tissue Elastography
In current study, The Mesh-free method based on weak-form formulation coupled with the ultrasound imaging technique is developed. This problem consists in computing the deformation of an elastic non-homogenous phantom by numerical methods (both Mesh-free and Finite Element) and converge their results to the measured deformation by the ultrasound. The shape functions of Mesh-free are approximate...
