Abstract
Ultrasound vibroacoustography is a new medical imaging technique that relies on the nonlinear interaction of high-frequency fields to produce a low-frequency acoustic emission. Combining the resolution obtained by using a high-frequency focused source with the clean (free of artifacts from multiple scattering) images obtained with low-frequency fields yields a clearer image of abnormal tissue than does traditional ultrasound. A modeling strategy for this imaging modality is presented that overcomes the traditional difficulties in modeling over the range of frequencies present in these experiments. Through a combination of appropriate approximations and exact methods, it is possible to obtain images that capture the basic structure of experimental data despite the use of a simplified physical model.

Abstract
Ultrasound vibro-acoustography is a novel medical imaging modality that combines the high resolution of high-frequency ultrasound with the speckle-free images obtained using low-frequency methods. This imaging modality relies on the non-linear interaction of two high frequency beams at slightly different frequencies. We describe the physics of ultrasound vibro-acoustography and outline a strategy for its modeling, simulation, and optimal design.
