Abstract
An ultrasound system visualizes shear wave propagation in real time by slowing down the propagation of the shear wave as seen by the ultrasound probe. The shear wave source propagates shear waves into the medium at a frequency ω. The ultrasound probe is vibrated by a vibrator at the frequency ω−Δω, where Δω is much smaller than ω. The wave propagation as seen by the ultrasound probe is slowed down by a factor Δω/ω. An appropriate value of Δω allows real-time visualization of the wave propagation. Variations include electronically producing a virtual vibration and the use of multiple shear wave sources.
