reconstruct my sino

[rasad-hub]

Hello, let me ask my question clearly. I have a sinogram matrix with dimensions of 180*300. Can I reconstruct this sinogram with your algorithms? If yes, with which geometry and are there any changes needed, or can I simply reconstruct it by placing my own sinogram?

Yes, that is the entire thing TIGRE does :)

The geometry you need to define is the one that was used to create the sinogram, its information you must have to do CT recon.
Once you have it, just load it in python/MATLAB and use TIGRE as explained in the demos. You can "simply reconstruct" if you use TIGRE appropiately, so do check the demos, particularly the one related to 2D tomography.
