Description
Computationally-efficient single-frequency acoustic solvers have many applications. Our interest is in therapeutic and diagnostic biomedical ultrasound. I will describe recent work on a class of numerical acoustic models of wave propagation through heterogeneous soft tissue media based on unconditionally convergent Neumann series, made efficient through the use of the Fast Fourier Transform. Comparisons will be give to the well-validated pseudospectral time domain model k-Wave, and the factors affecting the rate of convergence will be discussed.
