Dear all,
I used CASToR to recon simulation CT, it looks good with MLTR. But if there is offset in real detectors, the recon image looks terrible with the same .geom. Cuz there is offset in the horizontal and vertical directions in real detectors and source. How can I set the horizontal and vertical offset value in CASToR? Or any method to improve image quality?

I am grateful for any reply.
Best,
Hannah
