Shear wave construction with laterally moving radiation force excitations

Shear wave-based elasticity methods which quantify shear wave speed, c_s, are becoming clinically relevant as many pathological conditions change values of c_s in soft tissue. Reliable measurements require shear waves with high signal-to-noise ratio that propagate far enough to measure c_s. Push tonebursts must have long duration and/or high intensity, but ultrasound exposure regulations limit deposited energy so trade-offs must be made to find new solutions for creating shear waves for clinically reliable measurements.
