The attenuation of ultrasound propagation in soft tissue follows a frequency-dependent power law. To model the power law attenuation while also accounting for the dispersion in soft tissue, Treeby and Cox proposed a space-fractional wave equation. Calculating the time-domain Green's function of the Treeby-Cox wave equation requires numerical evaluations of an inverse Fourier transform in the spatial...
The attenuation of ultrasound propagating in human tissue follows a power law with respect to frequency. Several different models for power law attenuation have been developed, where many of these are partial differential equations that contain fractional derivatives in time or space. Some of these models are causal, and some are noncausal, yet all of these models describe attenuation that follows...
