17.09: Brad Treeby: Simulating wave propagation in ultrasonics and photoacoustics

Bradley Treeby, University College of London 

The accurate simulation of wave propagation in tissue realistic media has many applications in ultrasonics and photoacoustics. In this talk, I will give an overview of the open-source k-Wave Toolbox and it's application to time-domain simulations. The governing equations and numerical methods will be introduced, including the use of spatial fractional derivatives to account for acoustic absorption. Finally, I will discuss applications of the models in photoacoustic image reconstruction and exposimetry for high-intensity focused ultrasound.
