Abstract
Longitudinal shear waves (LSW) are waves with longitudinally polarized displacement that travel at the shear wave speed through depth when generated at the surface of tissues. In this study, we explore LSW generated by a circular glass plate in contact with the sample. Results demonstrated the potential of LSW in detecting an elasticity gradient along axial (resolution < 0.13 mm) and lateral (resolution < 0.78 mm) directions simultaneously. Finally, LSWs are used for the elastography of ex vivo mouse brain and demonstrated differentiated LSW speed values between the cerebral cortex (2.91 m/s) and cerebellum/midbrain (1.18 m/s) regions.
