The Development of Crawling Waves
In a recent discovery by Wu et al. (Z Wu, LS Taylor, DJ Rubens, KJ Parker "Sonoelastographic imaging of interference patterns for estimation of the shear velocity of homogeneous biomaterials" Ultrasound Med Biol 20(2)161-168, 2004), it was found that interfering shear waves could produce slowly propagating interference patterns with an apparent velocity much less than (but proportional to) the underlying true shear velocity. Termed 'crawling waves,' they are generated using a pair of mechanical sources vibrating at slightly offset frequencies. More importantly, these shear wave (interference) patterns can be visualized in real-time using sonoelastographic imaging techniques. In general, crawling wave images describe shear wave propagation patterns and allow for estimation of the spatial elastic properties in tissue, namely, shear velocity distributions.
