Dear CASToR users
I simulated a long axial FOV PET and now I want to reconstruct my ROOT file that includes huge data. Is CASToR capable of doing it?
Any help I would really appreciate it.
Best regards
Hi Hadi,
The datafile size should not be a problem for CASToR, but it mostly depends on the computing power of your machine/cluster, and on your patience 
Long axial FOV PET system will result in a huge number of lines of response that CASToR will have to process, not only for the reconstruction itself, but also for the generation of the sensitivity image. Currently there is no GPU support in CASToR, only parallel CPU implementation with MPI and OpenMP, so the processing of this kind of dataset will take quite some time.
Best regards,
