In diagnostic medical imaging, ultrasound waves traveling through tissue are longitudinal waves, whereas shear waves produced during transient elastography to assess liver stiffness are transverse waves.
Describe how the direction of oscillation in these shear waves differs from that in ultrasound waves, relative to the direction of energy propagation.
