  • Abstract
    Shear wave-based elasticity methods which quantify shear wave speed, cs, are becoming clinically relevant as many pathological conditions change values of cs in soft tissue. Reliable measurements require shear waves with high signal-to-noise ratio that propagate far enough to measure cs. 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.
