Software
Requirements
The code was tested with Matlab 7.9 (R2009b). Please feel free to contact us if you get any trouble with other versions. As some parts of the code use compiled executables, it might not be straightforward to run the code with free alternatives like Octave or Freemat.
Some scripts require the IRT toolbox [TGZ archive, 8.1 MB] of Jeff Fessler for NUFFT routines. Install this toolbox in your matlab path.
Download and install
The code is available here [ZIP archive, 270 KB]. Add the folder containing this code in your matlab path. Some C++ sources are distributed with the code. To compile them as MEX binaries, simply run 'make' in matlab prompt.
