    The simulation package Abersim

    On November 1st 2008 the open source ultrasound simulation package Abersim 2.0, a Matlab-base toolkit for simulation of 3D nonlinear forward propagation ultrasound fields, was released. This is a complete tool for investigating nonlinear (and linear) properties of forward propagating ultrasound fields, and is ideal for studying linear and nonlinear beam profiles from ultrasound arrays.
    See ntnu.no\abersim for more details.
