Abstract
In one aspect the invention relates to a shear wave generator. The shear wave generator includes a first piezoelectric element having a first polarity in electrical communication with a first electrode; a second piezoelectric element having a second polarity in electrical communication with a second electrode, wherein the second polarity is an inverse of the first polarity; a boundary layer disposed behind both the first piezoelectric element and the second piezoelectric element; and an excitation signal generator in electrical communication with the first electrode and the second electrode, wherein the first piezoelectric element vibrates in a first direction and the second piezoelectric element vibrates in a second direction in response to an excitation signal. In one embodiment, the piezoelectric elements are disposed within an ultrasound imaging probe.
