Thus, similar to dualMRI, knowledge of the stress distribution within the tissue or accurate determination of the boundary conditions is critical to solve for the modulus using inverse methods e. Would you please look and see if there is a C: Magnetic resonance elastography of brain tumors: Strain transfer characterization of multilayer agar phantom with different stiffness. Spatial characterization of corneal biomechanical properties with optical coherence elastography after UV cross-linking. Elastography is a powerful noninvasive mechano-imaging technique that can provide spatial pixel-by-pixel maps of mechanical parameters and behavior throughout a material, including strain, elastic and shear moduli, or viscoelasticity.

The stiffness of a tissue, or its ability to resist deformation when subjected to an applied force, is often indicative of the pathologic, regenerative or aging state in most organs in the body, including heart, liver, and brain.

Shear wave in heterogeneous material is difficult to analyze. This, in turn, allows use of a wider range of noninvasive microscopic excitation methods e. SYS The system cannot find the file specified. Click Continue and the page will refresh.
