Time domain simulation of harmonic ultrasound images and beam patterns in 3d using the k-space pseudospectral method

Treeby, Bradley; Tumen, Mustafa; Cox, Benjamin

Description

A k-space pseudospectral model is developed for the fast full-wave simulation of nonlinear ultrasound propagation through heterogeneous media. The model uses a novel equation of state to account for nonlinearity in addition to power law absorption. The spectral calculation of the spatial gradients enables a significant reduction in the number of required grid nodes compared to finite difference methods. The model is parallelized using a graphical processing unit (GPU) which allows the...[Show more]
