Thanks! I'll have a good look at it sometime in the next couple of weeks :) |

Hi AnderBiguri, I added a new pull request here as I further modified the .cu code of backprojection and fixed some bugs in the last pull request.
I checked the modified code and added a demo named "d025_OffsetSource" in the demo dir. The results of the demo looks good. For example, the difference image between the projection with and without source offset is:
And the reconstruction images are similar:( Left: reference image without source offset; Right: reconstruction image with 60 mm source offset)
Just recompile the code and run the demo you can also get these results. Do you think this is correct? Because it is hard for me to check all the cuda code, so I'm not sure if there is still minor but import parts I need to consider.
