In this study, we try to build the fractional derivative PDE model for broadband ultrasound propagation through human tissues.Computational Engineering, Finance, and ScienceComputational ComplexityG1.2, G1.8A note on fractional derivative modeling of broadband frequency-dependent absorption: Model IIItext
