Welcome to the home page for Field II! Here you will find all the information about the program along with executables and examples that you can download.

The Field IIpro parallel version has now been released for use. It is found in versions for both Matlab and Octave and it also exist in a C library version usable for buidling stand-alone executables. More information about the program can be found at: Field IIpro in the left menu. Here you can also find a paper about the performance of Field IIpro.

Version 3.24 of Field II for widows has been released for Matlab 8.10. This mex file is compiled using the GNU gcc compiler and should hopefully fix the problem with Field II under windows. You can find the code at: Download/For Matlab 8.20 in the left menu.

You can now follow Field II on LinkedIn and post comments and discussions. You can freely join the group named: Field II Ultrasound Simulation Program, where news about new version of Field II will be posted.

Field II is a program for simulating ultrasound tranducer fields and ultrasound imaging using linear acoustics. The programs uses the Tupholme-Stepanishen method for calculating pulsed ultrasound fields. The program is capable of calculating the emitted and pulse-echo fields for both the pulsed and continuous wave case for a large number of different transducers. Also any kind of linear imaging can be simulated as well as realistic images of human tissue. The program is running under Matlab on a number of different operating system (Windows, Linux, Mac OS X), and the programs are currently free to use under certain restrictions (see copyright).

The latest release of the program is version 3.24 of May 12, 2014. Note that this code will work with Matlab 8.20 under Linux, Mac and Windows in 64 bits versions.

Note that for the Windows 64 bits version you have to have the Microsoft Visual Studio 2012 run-time libraries for this version to work. This you can either get by installing the compiler and using mex -setup or download the Microsoft Visual Studio 2012 run-time libraries from the link: http://www.microsoft.com/en-us/download/details.aspx?id=30679

The latest News is from May 24, 2014 about version 3.24 of Field II for windows compiled with the GNU gcc compiler.

Why a new web-site? The University have decided to close down the Linux server running this site in May 2012, and I had to find an alternative. I was also increasingly getting tired of having yet another web-addres that people should search to find. I have therefore decided to privately host this web-address, and I hope to keep it alive as long as there is any interest in Field II, which I hope will be for a very long time. If you have any comments or suggestions you can contact me at j.arendt.jensen@gmail.com.

Sincerely

Jørgen Arendt Jensen
