Exact analytical expressions for the spatial impulse response are available for certain transducer geometries. These exact expressions for the spatial impulse response, which are only available for lossless media, analytically evaluate the Rayleigh i

When applied to compressional waves, the Caputo time-fractional wave equation describes power law attenuation in soft tissue. However, when applied to shear waves, the Caputo wave equation produces some unexpected behavior. To demonstrate examples of

An exact analytical time-domain Green’s function is obtained for the van Wijngaarden wave equation when two of the constant coefficients satisfy a certain equality. This analytical expression enables numerical assessments demonstrating that lossy t

Time-domain estimates of the shear wave speed are obtained by performing cross-correlations or by evaluating the time-to-peak for two laterally separated shear wave particle velocity waveforms, where the distance divided by the propagation time yield

The Chen-Holm and Treeby-Cox wave equations are space-fractional partial differential equations that describe power law attenuation of the form α ( ω ) ≈ α 0 | ω | y. Both of these space-fractional wave equations are causal, but the phase veloc
