Abstract
A vibro-acoustography imaging system that generates a map of the mechanical response of a target to an acoustic radiation force, usually in low kHz range by a confocal geometry. The system generates two focused sinusoidal beams to produce a stress field at the beat frequency, which is a function of vibration and acoustic emissions field in terms of mechanical properties. A highly sensitive hydrophone is then used for detection of the acoustic emissions field, the amplitude of which may be correlated to the mechanical properties of the target tissue.
