The regular ifanbeam function discards part of the sinogram data generated by fanbeam : it keeps only a 180° + fanAngle angular range, and reconstructs like a short scan.

This was mentioned and proved by a piece of test code on the forum http://www.mathworks.fr/matlabcentral/answers/53299-can-ifanbeam-use-all-the-sinogram-generated-by-fanbeam

This modified version contains just a few tweaks, which make ifanbeam use all the data and exploit its redundancy.

Hi I ran the modified version but it gives me some errors. Apparently some of the modified sub functions are not included in the download links. Can you please include those as well. Tanx
