FREE acoustics toolbox for MATLAB

Features

k-Wave is a freely available 3rd party toolbox for MATLAB developed for the time-domain simulation of acoustic wave propagation. It is based on a grid-based iterative k-space pseudospectral solution method to coupled first-order acoustic equations. The software has been designed to make tissue realistic simulations of acoustics, ultrasound, and photoacoustics fast and easy to use. The toolbox was developed by Bradley Treeby, now at the Australian National University, and Ben Cox, from the Photoacoustic Imaging Group in the Department of Medical Physics and Bioengineering at University College London (UCL), and includes:

1
An advanced time-domain model of acoustic wave propagation that can account for nonlinearity, acoustic heterogeneities, and power law absorption (1D, 2D, and 3D)
2
The ability to model arbitrary pressure and velocity sources, arbitrary detection surfaces with directional elements, and diagnostic ultrasound probes.
3
The option to use the forward model as a flexible time reversal image reconstruction algorithm for photoacoustic tomography with an arbitrary measurement surface
4
A fast, one-step, photoacoustic image reconstruction algorithm for data recorded on a linear (2D) or planar (3D) measurement surface
5
Optional input parameters to adjust visualisation and performance, including options to generate movies and to run the simulations on a graphics processing unit (GPU)
6
Many simple to follow tutorial examples to illustrate the capabilities of the toolbox
