1C-2. Rapid Shear Wave Measurement for SDUV with Broadband Excitation Pulses and Non-Uniform Sampling

We propose a method using broadband tone burst excitation pulses with non-uniform sampling for Shearwave Dispersion Ultrasound Vibrometry (SDUV). The method allows long excitation pulses with a high PRF of detection pulses to induce a strong tissue motion and obtain strong detection signal. The method also simultaneously estimates all harmonics of tissue motion induced by the broadband excitation pulses so that the shear wave can be rapidly estimated with minimized bias and distortion.
