Figure 3. — Measurement of wave speed using ultrasound surface wave elastography. A, Ultrasound B-mode image of the eye. B, Several points in the central 6 mm of the cornea were selected (blue dots) to measure wave propagation by using ultrasound tracking. C, The wave phase change with position, in response to a 0.1 second excitation at 100 Hz, was used to measure the wave speed.
