The same month after the publication of our work, Ref. [1], in Magnetic Resonance in Medicine, we released our software to two different sites, Matlab Central and Wolfram Library Archive. Matlab Central and Wolfram Library Archive are two very wonderful sites for sharing software. Since software development is a on-going process, it is not convenient to share ideas, comments and to update/upload the software on these sites. Hence, only major releases will be made on these sites and I shall use this google site for sharing ideas and comments. Of course, your comments or questions are welcome.

The archive file, STBBFolder, is basically the same as the one on the Matlab Central. Thanks to Christine, a student from Germany, whose questions dated Aug 11, 2009 have led me to add a few lines of MATLAB codes to illustrate the steps needed to perform FFT on the k-space signals of the 3D Shepp-Logan phantom. The transformed image domain signals are then compared with the analytical image domain signals, refer to the Matlab file below. In the revised SampleTest.m, I used imtool. So, please make sure that you click on a menu that allows you to change contrast (min=0.0 and max=3.0 should be fine and these values should be applied to both imtool panels), see the screen shot here.    

Finally, if you find the software useful and use the software in your research work, please spread the words by citation or word of mouth. Thanks.
