Constructive shearwave imaging: Feasibility and improvements in SNR

Conference Paper

Shear wave elasticity imaging (SWEI) measures mechanical properties of tissues and has been used to characterize tissue stiffness, but SWEI is limited by low displacement SNR in stiff media such as skin. A method for repeatable measurement of skin elasticity is critical for longitudinal monitoring of sclerotic diseases such as morphea. Constructive Shearwave Interference (CSI) overcomes the SNR limitations of conventional SWEI in skin by generating greater shear wave displacements at the constructive center of an acoustic radiation force ring of excitation. The objective of this study is to characterize the increase in displacement SNR from constructively-interfering shear waves.
