FIG. 1.

(Color online) Ultrasound based surface wave model for measuring elastic properties of tissue. The surface wave is generated noninvasively by the piston-like localized radiation force of ultrasound. The surface wave is measured noncontact with a laser vibrometer.

FIG. 2.

(Color online) Experimental setup for measurement of the surface wave in an ultrasound phantom. The ultrasound transducer is behind the phantom which generates a force on the front surface of the phantom. The surface vibration on the front surface with paint is measured with a laser vibrometer.
